mounter or component placement machine, picks electronic components from feeders or trays, checks their position and orientation with a vision system, and places them onto solder-paste-printed PCB pads. The right machine is determined by the real component and product mix, not by headline placement speed alone.<\/p>\n<p>For a first-time buyer, the specification sheet can be deceptive. Two machines may both claim 80,000 components per hour (CPH), yet deliver very different output when they run the same board. Feeder arrangement, component variety, nozzle changes, vision time, board transfer, replenishment, and line balance all affect the result.<\/p>\n<p>This guide explains the machine from the inside out, then gives a practical method for comparing platforms. It is intended for production engineers, maintenance teams, equipment buyers, and companies evaluating a new or used SMT line.<\/p>\n<blockquote class=\"key-answer\">\n<p><strong>Short answer:<\/strong> Choose an SMT pick-and-place machine by studying your board data, component list, production volume, changeover frequency, quality requirements, and local service capability. Treat catalog CPH as a reference measured under specified conditions. Ask each supplier to run the same board and bill of materials before comparing output.<\/p>\n<\/blockquote>\n<h2 id=\"what-is-an-smt-pick-and-place-machine\">What Is an SMT Pick-and-Place Machine?<\/h2>\n<p>An SMT pick-and-place machine is automated assembly equipment that transfers surface-mount devices from packaging to programmed locations on a printed circuit board. It normally operates after solder paste printing and solder paste inspection, and before reflow soldering.<\/p>\n<p>A typical SMT line follows this sequence:<\/p>\n<ol>\n<li>A PCB loader feeds bare boards into the line.<\/li>\n<li>A solder paste printer deposits paste through a stencil.<\/li>\n<li>Solder paste inspection (SPI) checks deposit volume, height, area, and alignment.<\/li>\n<li>One or more pick-and-place machines populate the board.<\/li>\n<li>A reflow oven melts the solder and forms the joints.<\/li>\n<li>Automated optical inspection (AOI), X-ray inspection, or electrical testing checks the result.<\/li>\n<\/ol>\n<p>The placement machine does not create the solder joint. Its job is to put the correct component in the correct location, at the correct angle and placement force, with enough consistency for the reflow process to finish the assembly.<\/p>\n<p>\u201cChip mounter\u201d and \u201cSMT pick-and-place machine\u201d are often used interchangeably. In some factories, however, <em>chip shooter<\/em> refers more narrowly to a high-speed machine optimized for small passive components, while <em>flexible mounter<\/em> refers to a machine that handles ICs, connectors, and a wider component range.<\/p>\n<h2 id=\"how-does-an-smt-pick-and-place-machine-work\">How Does an SMT Pick-and-Place Machine Work?<\/h2><p class=\"related-guide\">See how placement connects with printing, inspection and reflow in the <a href=\"https:\/\/www.smtbase.com\/resources\/complete-smt-production-line-guide\/\">complete SMT production line guide<\/a>.<\/p>\n<figure class=\"smt-article-figure wp-block-image size-full\"><img src=\"https:\/\/smtbase.com\/wp-content\/uploads\/2026\/08\/real-smt-pick-and-place-head-operation.jpg\" alt=\"Real SMT pick-and-place head operating above a printed circuit board\" width=\"1536\" height=\"1024\" class=\"wp-image-846\" loading=\"lazy\" decoding=\"async\"><figcaption>A real placement head working over a PCB. The image shows the enclosed mechanism used to pick, inspect and place components.<\/figcaption><\/figure>\n<p>The machine repeats a coordinated cycle of board positioning, component feeding, pickup, vision correction, placement, and process verification. Each step is fast, but a small weakness in any one of them can reduce output or create intermittent defects.<\/p>\n<h3 id=\"1-the-pcb-enters-and-is-positioned\">1. The PCB enters and is positioned<\/h3>\n<p>The conveyor moves the PCB into the placement area. Board stops, clamps, and support pins hold it steady. The upward-looking or downward-looking camera, depending on machine design, reads fiducial marks to calculate the board&#39;s actual X, Y, and rotational offset.<\/p>\n<p>Good fiducial recognition matters because a PCB is never located in exactly the same mechanical position on every cycle. Local fiducials may also be used around fine-pitch packages when the required placement tolerance is tighter than the board-level correction can provide.<\/p>\n<h3 id=\"2-feeders-present-the-components\">2. Feeders present the components<\/h3>\n<p>Most small components arrive in tape-and-reel packaging. A tape feeder advances the carrier tape by one pocket and exposes the next component for pickup. Other supply methods include trays, tubes, sticks, waffle packs, bulk feeders, and custom odd-form feeders.<\/p>\n<p>Feeding is part of the placement process, not a separate purchasing detail. An inaccurate or poorly maintained feeder can cause pickup errors, damaged cover tape, unstable component position, or repeated machine stops. Feeder availability also determines how many component types can remain loaded and how long a product change takes.<\/p>\n<h3 id=\"3-a-nozzle-picks-the-component\">3. A nozzle picks the component<\/h3>\n<p>The placement head moves over the feeder. A nozzle descends, applies vacuum, and lifts the component from its pocket. Vacuum sensing and side-view cameras may confirm whether the component was picked correctly.<\/p>\n<p>The nozzle must match the component&#39;s top surface, dimensions, weight, and material. A nozzle that is too small may not hold the part securely. One that is too large may touch nearby tape features or cover vision-relevant edges. Worn nozzle tips, blocked air paths, damaged reflectors, and weak vacuum are common causes of unstable pickup.<\/p>\n<h3 id=\"4-the-vision-system-identifies-and-corrects-the-part\">4. The vision system identifies and corrects the part<\/h3>\n<p>Before placement, the machine measures the component&#39;s position and rotation relative to the nozzle. Depending on the component and platform, it may inspect the body, edges, leads, bumps, or other features.<\/p>\n<p>The control system combines component correction with the PCB fiducial correction. It then calculates the motion needed to place the part at its programmed coordinates. Fine-pitch ICs and unusual packages generally require more vision processing than small rectangular chips, so the component mix changes the achievable cycle time.<\/p>\n<h3 id=\"5-the-component-is-placed\">5. The component is placed<\/h3>\n<p>The head moves to the target location, rotates the component, lowers the nozzle, and places the part into the solder paste. Placement height and force need to be controlled. Too much force can damage a fragile component, disturb the paste, flex the PCB, or accelerate nozzle wear. Too little downward travel may leave the component inadequately seated.<\/p>\n<h3 id=\"6-production-data-is-recorded\">6. Production data is recorded<\/h3>\n<p>Modern machines record events such as pickup errors, recognition failures, feeder status, component counts, alarms, and placement results. Factory software may connect these records to material verification, traceability, maintenance, and line monitoring systems.<\/p>\n<p>The data is most useful when the factory has a clear reaction plan. A pickup-error chart has little value if no one checks whether the cause is the tape, feeder, nozzle, vacuum circuit, or component library.<\/p>\n\n<figure class=\"smt-real-photo\"><img src=\"https:\/\/smtbase.com\/wp-content\/uploads\/2026\/08\/juki-smt-pick-and-place-production-line.webp\" alt=\"JUKI modular SMT pick-and-place machines installed with feeder banks in a production line\" width=\"1280\" height=\"853\" loading=\"lazy\" decoding=\"async\"><figcaption>Real production equipment shows why machine configuration matters: the installed heads, feeder banks, conveyors and line arrangement determine what the platform can actually run.

For example, replacing a nozzle may not solve a pickup problem if the feeder&#39;s pickup position is drifting or the vacuum filter is restricted.<\/p>\n<h2 id=\"types-of-smt-pick-and-place-machines\">Types of SMT Pick-and-Place Machines<\/h2>\n<p>Placement machines are usually described as high-speed, flexible, modular, or odd-form systems. The boundaries are less rigid than they once were: current platforms often combine multiple head options and can cover a broad range of components within one product family.<\/p>\n<h3 id=\"high-speed-chip-placement-machines\">High-speed chip placement machines<\/h3>\n<p>These machines prioritize small components and high area productivity. They commonly use multi-spindle or rotary heads and are suited to boards with large quantities of resistors, capacitors, and small ICs.<\/p>\n<p>They are a strong fit when the product mix is stable and small-chip volume is the main constraint. Their catalog speed should still be tested with the actual board. A product containing many feeder locations, multiple nozzle types, or frequent replenishment can perform far below an optimum-condition figure.<\/p>\n<h3 id=\"flexible-or-multifunction-mounters\">Flexible or multifunction mounters<\/h3>\n<p>Flexible mounters handle a broader component range, including larger ICs, connectors, shields, and parts supplied in trays. They may trade some small-chip speed for component capability, placement force control, or higher-accuracy vision functions.<\/p>\n<p>A flexible mounter is often placed after a chip-focused machine, although one capable platform may be enough for low- to medium-volume production.<\/p>\n<h3 id=\"modular-placement-systems\">Modular placement systems<\/h3>\n<p>A modular line uses configurable machines or modules that can be combined around the product mix. This allows a factory to distribute small chips, fine-pitch packages, and larger components across different heads or machines.<\/p>\n<p>The main advantage is line balancing. The main purchasing challenge is that the full result depends on configuration: head type, lane mode, feeder setup, board dimensions, software options, and neighboring equipment all matter.<\/p>\n<h3 id=\"odd-form-and-insertion-capable-systems\">Odd-form and insertion-capable systems<\/h3>\n<p>Some components cannot be handled reliably by a standard vacuum nozzle or ordinary tape feeder. Large connectors, transformers, radial or axial parts, and mechanically inserted components may require grippers, force control, lead inspection, clinching, or dedicated insertion equipment.<\/p>\n<p>Before assuming that a \u201clarge component\u201d specification covers an odd-form part, provide the supplier with a drawing, mass, center of gravity, pickup surface, packaging method, lead geometry, and required insertion force.<\/p>\n\n<h2 id=\"how-is-an-smt-pick-and-place-machine-programmed\">How Is an SMT Pick-and-Place Machine Programmed?<\/h2>\n<p>An SMT pick-and-place machine program converts PCB design data into machine instructions: which feeder supplies each component, which nozzle handles it, where it is placed, its rotation, and which vision checks apply. The exact software differs by brand, but the data and first-board checks are broadly similar.<\/p>\n<ol class=\"program-flow\">\n  <li><strong>Prepare BOM and centroid data.<\/strong> Confirm reference designators, package names, X\/Y coordinates, rotation conventions and board origin.<\/li>\n  <li><strong>Create component library records.<\/strong> Define body dimensions, pickup position, height, polarity, vision method and allowed tolerance.<\/li>\n  <li><strong>Assign feeders and nozzles.<\/strong> Match tape width, pocket pitch, component presentation and nozzle geometry to each part.<\/li>\n  <li><strong>Set board and fiducials.<\/strong> Define the PCB or panel dimensions, conveyor direction, support locations and global or local fiducials.<\/li>\n  <li><strong>Optimize the sequence.<\/strong> Balance heads, reduce unnecessary travel and account for nozzle changes, tray pickups and large components.<\/li>\n  <li><strong>Run a first-board check.<\/strong> Verify polarity, rotation, placement position, pickup stability and program-to-BOM traceability before releasing production.<\/li>\n<\/ol>\n<p>A common failure is treating the centroid file as a finished machine program. It is only a starting point. CAD rotation conventions, package origins and component-library names often differ between design software and placement platforms. A 90-degree rotation error or a mismatched polarity rule can affect every board in the lot.<\/p>\n<div class=\"field-note\"><strong>Data package to request before a machine demonstration<\/strong><span>Send the supplier one representative BOM, centroid file, panel drawing and component list. Ask them to return the proposed feeder setup, nozzle plan, calculated cycle time and any parts the machine cannot handle automatically.<\/span><\/div>\n<h2 id=\"what-do-cph-accuracy-and-cpk-actually-mean\">What Do CPH, Accuracy, and Cpk Actually Mean?<\/h2>\n<p>CPH, placement accuracy, and process capability describe different aspects of a machine. None of them, by itself, predicts whether the complete line will meet a production target.<\/p>\n<h3 id=\"cph-components-per-hour\">CPH: components per hour<\/h3>\n<p>CPH is the number of placements a machine can make in one hour. Manufacturer figures are often measured under optimum or defined conditions. JUKI, for example, describes the RX-8&#39;s 100,000 CPH figure as an installed value under its optimum conditions. That qualifier is essential when comparing machines.<\/p>\n<p>Actual output may be lower because of:<\/p>\n<ul>\n<li>PCB loading, clamping, and fiducial-reading time;<\/li>\n<li>the distance between feeders and placement coordinates;<\/li>\n<li>component-recognition and nozzle-change time;<\/li>\n<li>feeder replenishment and operator response;<\/li>\n<li>rejected pickups and recognition retries;<\/li>\n<li>product changeover and program verification;<\/li>\n<li>imbalance between placement machines or other line equipment.<\/li>\n<\/ul>\n<p>A useful comparison asks each supplier to calculate and then demonstrate the cycle time for the same centroid data, BOM, panel, feeder plan, and quality settings.<\/p>\n\n<h3>Convert nominal CPH into a board-level target<\/h3>\n<p>Start with placements per board and the required boards per hour. A board with 650 placements running at 60 boards per hour needs 39,000 successful placements per hour before allowances for fiducial reading, board transfer, rejected pickups, replenishment and changeover. Compare that requirement with a demonstrated cycle time, not only the catalogue CPH.<\/p>\n<p>For a mixed-product factory, also record changeover minutes, first-board verification time and feeder preparation labor. Those figures often change the business case more than a small difference in theoretical placement speed.<\/p>\n<h3 id=\"placement-accuracy\">Placement accuracy<\/h3>\n<p>Placement accuracy indicates how closely the machine places a component to the target position under specified test conditions. It may be stated in micrometres and paired with a Cpk value. The measurement method, component type, reference material, head, speed mode, and test environment may differ between suppliers.<\/p>\n<p>Do not compare two accuracy numbers until the conditions are understood. A machine can also be highly accurate yet produce defects if the PCB is unsupported, the component data is wrong, the nozzle is worn, or solder paste printing is unstable.<\/p>\n<h3 id=\"cpk-process-capability\">Cpk: process capability<\/h3>\n<p>Cpk expresses how well a process distribution fits within defined limits while accounting for centering. A higher Cpk generally indicates more margin between the process variation and the specification limits. A quoted machine value is not the same as the Cpk of the finished assembly process, which also depends on materials, printing, board design, reflow, inspection, and measurement methods.<\/p>\n<h3 id=\"component-range\">Component range<\/h3>\n<p>The minimum and maximum component dimensions are useful screening criteria, but they do not prove that every part between those limits is supported. Check:<\/p>\n<ul>\n<li>component length, width, and height;<\/li>\n<li>weight and center of gravity;<\/li>\n<li>package and lead type;<\/li>\n<li>available pickup surface;<\/li>\n<li>vision and lighting requirements;<\/li>\n<li>packaging format;<\/li>\n<li>nozzle or gripper availability;<\/li>\n<li>required placement or insertion force.<\/li>\n<\/ul>\n<h3 id=\"feeder-capacity\">Feeder capacity<\/h3>\n<p>Feeder capacity affects both product capability and changeover work. The nominal number of feeder positions is only a starting point because wide feeders, trays, stick feeders, and accessories consume space differently.<\/p>\n<p>Ask for the feeder plan for your BOM. It should identify every component, feeder width, alternate supply method, replenishment frequency, and shared setup opportunity.<\/p>\n<h2 id=\"examples-of-current-placement-platforms\">Examples of Current Placement Platforms<\/h2><p class=\"related-guide\">For a broader comparison of manufacturers, model families and support considerations, see the <a href=\"https:\/\/www.smtbase.com\/resources\/major-smt-equipment-brands-machine-series\/\">major SMT equipment brands and machine series guide<\/a>.<\/p>\n<p>The machines below illustrate different approaches in the current market.

This prevents a sales specification from becoming the factory&#39;s production assumption.<\/p>\n<h3 id=\"step-1-define-the-product-mix\">Step 1: Define the product mix<\/h3>\n<p>Prepare representative products rather than only the easiest or highest-volume board. For each product, collect:<\/p>\n<ul>\n<li>annual and peak demand;<\/li>\n<li>lot size and number of changeovers;<\/li>\n<li>PCB and panel dimensions, thickness, weight, and warpage limits;<\/li>\n<li>centroid or XY placement data;<\/li>\n<li>BOM with package, quantity, and approved alternatives;<\/li>\n<li>component packaging and reel quantities;<\/li>\n<li>fine-pitch, BGA, fragile, tall, heavy, or odd-form parts;<\/li>\n<li>traceability and inspection requirements.<\/li>\n<\/ul>\n<p>If future products are uncertain, define a realistic expansion envelope instead of buying every possible option.<\/p>\n<h3 id=\"step-2-calculate-the-required-line-output\">Step 2: Calculate the required line output<\/h3>\n<p>Convert demand into boards per hour while allowing for planned downtime, breaks, preventive maintenance, material replenishment, and product changeover. Then calculate placements per board and identify which component group will constrain the line.<\/p>\n<p>A simple estimate is:<\/p>\n<p><code>required placements per hour = required boards per hour \u00d7 placements per board<\/code><\/p>\n<p>This is only a starting point. The detailed simulation should include board handling, feeder travel, vision, nozzle changes, and the division of work between machines.<\/p>\n<h3 id=\"step-3-match-the-component-and-feeder-requirements\">Step 3: Match the component and feeder requirements<\/h3>\n<p>Confirm that every component has a qualified supply method, vision method, nozzle or gripper, and placement process. The machine must also have enough practical feeder capacity for the intended setup strategy.<\/p>\n<p>For high-mix production, the cost of feeders and offline preparation can be as important as the machine price. Shared feeder setups, verification systems, and feeder carts may save more production time than a modest increase in catalog CPH.<\/p>\n<h3 id=\"step-4-evaluate-quality-and-process-controls\">Step 4: Evaluate quality and process controls<\/h3>\n<p>Ask how the system handles:<\/p>\n<ul>\n<li>wrong-component prevention;<\/li>\n<li>barcode and material verification;<\/li>\n<li>fiducial and local-fiducial recognition;<\/li>\n<li>pickup and post-placement checks;<\/li>\n<li>component height and placement force;<\/li>\n<li>board warpage and support;<\/li>\n<li>traceability records;<\/li>\n<li>calibration and preventive maintenance.<\/li>\n<\/ul>\n<p>Quality functions should be demonstrated with your difficult parts. A feature listed as optional, under development, or dependent on another software package should be identified before the purchase order.<\/p>\n<h3 id=\"step-5-run-a-representative-acceptance-test\">Step 5: Run a representative acceptance test<\/h3>\n<p>Use the same board, program data, components, feeders, and operating rules for every shortlisted platform. Record:<\/p>\n<ul>\n<li>sustained boards per hour, not only a short peak;<\/li>\n<li>pickup and recognition error rates by component;<\/li>\n<li>replenishment and changeover time;<\/li>\n<li>first-pass yield after printing and reflow;<\/li>\n<li>operator interventions and alarm recovery;<\/li>\n<li>actual air and power requirements;<\/li>\n<li>program preparation and optimization time.<\/li>\n<\/ul>\n<p>Agree on acceptance criteria before the test. If possible, retain the test logs and exact software or machine configuration used.<\/p>\n<h3 id=\"step-6-check-lifetime-support\">Step 6: Check lifetime support<\/h3>\n<p>The lowest purchase price can become expensive if feeders, nozzles, calibration, software support, or critical spares are hard to obtain. Evaluate local service response, training, documentation, remote support, software policy, and parts availability.<\/p>\n<p>For a used machine, confirm whether the original manufacturer or a qualified independent service provider can still support its controller, cameras, servo system, operating software, and proprietary calibration tools.<\/p>\n\n<figure class=\"smt-real-photo\"><img src=\"https:\/\/smtbase.com\/wp-content\/uploads\/2026\/08\/automated-smt-pick-and-place-production-line.jpg\" alt=\"Automated SMT production line with pick-and-place machines, component reels and operator interfaces\" width=\"1920\" height=\"700\" loading=\"lazy\" decoding=\"async\"><figcaption>A placement machine must be evaluated as part of the full line.

They rely on incomplete input data or assume that a headline number represents the complete process.<\/p>\n<h3 id=\"comparing-only-maximum-cph\">Comparing only maximum CPH<\/h3>\n<p>Maximum CPH is useful for screening, but it does not represent sustained output on a mixed-component board. Request a simulation and a physical test using the same product data.<\/p>\n<h3 id=\"ignoring-the-feeder-and-nozzle-ecosystem\">Ignoring the feeder and nozzle ecosystem<\/h3>\n<p>A machine without enough correct feeders and nozzles cannot run the planned products. Include these items, their maintenance tools, and a sensible spare quantity in the total project cost.<\/p>\n<h3 id=\"treating-every-component-within-the-size-range-as-qualified\">Treating every component within the size range as qualified<\/h3>\n<p>Physical dimensions do not describe pickup surface, reflectivity, lead shape, mass distribution, coplanarity, packaging, or placement force. Review unusual parts individually.<\/p>\n<h3 id=\"buying-without-a-defined-acceptance-test\">Buying without a defined acceptance test<\/h3>\n<p>Terms such as \u201chigh speed\u201d and \u201chigh accuracy\u201d are not acceptance criteria. State the product, run conditions, output, quality measures, and allowed interventions in writing.<\/p>\n<h3 id=\"overlooking-line-balance\">Overlooking line balance<\/h3>\n<p>A faster placement machine will not raise output if the printer, oven, inspection system, board handler, or second mounter is the constraint. Evaluate the whole SMT production line.<\/p>\n<h3 id=\"underestimating-support-and-obsolescence\">Underestimating support and obsolescence<\/h3>\n<p>Used machines may appear attractive until a failed controller, camera, drive, or license stops production. Check critical spare availability before purchase, not after the first fault.<\/p>\n<h2 id=\"spare-parts-and-maintenance-what-commonly-needs-attention\">Spare Parts and Maintenance: What Commonly Needs Attention?<\/h2>\n<figure class=\"smt-article-figure wp-block-image size-full\"><img src=\"https:\/\/smtbase.com\/wp-content\/uploads\/2026\/08\/smt-tape-feeder-bank.png\" alt=\"Bank of SMT tape feeders presenting reeled components to a pick-and-place machine\" width=\"1536\" height=\"1024\" class=\"wp-image-848\" loading=\"lazy\" decoding=\"async\"><figcaption>Installed tape feeders advance carrier tape and present each component at a repeatable pickup position.<\/figcaption><\/figure>\n<p>Placement stability depends on small, frequently used parts as well as major assemblies.

A compatible part is made as an alternative intended to fit a stated application.<\/p>\n<p>Compatible parts can offer cost and lead-time benefits for suitable applications, but compatibility must be checked by part number, machine revision, dimensions, material, tolerances, and function. Safety devices, precision calibration components, high-value electronic assemblies, and parts whose failure can damage the machine deserve a stricter risk review.<\/p>\n<p>An independent supplier should state its relationship clearly. It should not imply authorization by JUKI, Hanwha, Panasonic, Fuji, Yamaha, or another manufacturer unless that status is genuine and documented.<\/p>\n<h2 id=\"checklist-for-buying-a-used-pick-and-place-machine\">Checklist for Buying a Used Pick-and-Place Machine<\/h2>\n<p>A used machine should be assessed as a configured production system, not as a cabinet with a model label. Its condition, options, accessories, software, and support path determine its real value.<\/p>\n<p>Check the following before purchase:<\/p>\n<ul>\n<li>serial number, build year, operating hours, and service records;<\/li>\n<li>exact head, camera, conveyor, and feeder-bank configuration;<\/li>\n<li>installed software version, licenses, passwords, and backup media;<\/li>\n<li>calibration status and available calibration tools;<\/li>\n<li>placement repeatability using a representative test board;<\/li>\n<li>condition of spindles, guides, conveyors, cables, fans, and pneumatics;<\/li>\n<li>included feeders, nozzles, tray units, carts, and accessories;<\/li>\n<li>compatibility with local voltage, frequency, air supply, and safety rules;<\/li>\n<li>rigging, shipping locks, installation, training, and restart support;<\/li>\n<li>availability and lead time of critical electronic and mechanical spares.<\/li>\n<\/ul>\n<p>Request a live run rather than only a power-on video. A machine that boots successfully may still have placement, vision, feeder, or software problems that appear only during production.<\/p>\n<h2 id=\"frequently-asked-questions\">Frequently Asked Questions<\/h2>\n<h3 id=\"is-a-chip-mounter-the-same-as-an-smt-pick-and-place-machine\">Is a chip mounter the same as an SMT pick-and-place machine?<\/h3>\n<p>Usually, yes. Both terms describe equipment that places surface-mount components on a PCB. Some factories use \u201cchip shooter\u201d for a machine focused on high-speed passive-component placement and \u201cflexible mounter\u201d for a broader component range.<\/p>\n<h3 id=\"what-does-cph-mean-on-an-smt-machine\">What does CPH mean on an SMT machine?<\/h3>\n<p>CPH means components per hour. It is a placement-speed measure, often recorded under manufacturer-defined or optimum conditions. Actual factory output depends on the board, BOM, feeders, vision time, nozzle changes, replenishment, errors, and line balance.<\/p>\n<h3 id=\"how-many-pick-and-place-machines-does-an-smt-line-need\">How many pick-and-place machines does an SMT line need?<\/h3>\n<p>The answer depends on placements per board, required boards per hour, component mix, and the capability of each configured machine. A prototype line may use one flexible mounter. A high-volume line may use several machines so that small chips, fine-pitch parts, and larger components are balanced across the line.<\/p>\n<h3 id=\"can-one-machine-place-every-component-on-a-board\">Can one machine place every component on a board?<\/h3>\n<p>Sometimes, but not automatically. Confirm the size, height, weight, pickup surface, package, vision needs, packaging, and placement force for every unusual component. Some odd-form or insertion parts require a gripper, special feeder, or separate machine.<\/p>\n<h3 id=\"what-information-is-needed-to-identify-an-smt-replacement-part\">What information is needed to identify an SMT replacement part?<\/h3>\n<p>Provide the machine brand, full model, serial number, original part number, assembly location, feeder or head model, photos of all labels and connectors, dimensions, and fault symptoms. This reduces the risk of ordering a visually similar but incompatible revision.<\/p>\n<h2 id=\"a-practical-final-test\">A Practical Final Test<\/h2>\n<p>Do not ask, \u201cWhich machine has the highest CPH?\u201d Ask, \u201cWhich configured line can produce our representative boards at the required rate and quality, with manageable changeovers, support, and lifetime cost?\u201d<\/p>\n<p>That question forces the comparison back to evidence. It also gives engineering, production, maintenance, and purchasing teams a common acceptance standard.<\/p>\n<p>If you need help checking a replacement part, send SMTBase the machine model, original part number, installed position, and clear photos.
