If yes, the review starts well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">File or order review comes before SMT production in common PCB assembly workflows.

A line that says \u201c10k resistor\u201d may be enough for a prototype discussion, but it is not enough for controlled sourcing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Approved alternates help, too. If one MPN is unavailable, the supplier can quote an approved substitute instead of stopping the RFQ. The key is control. Alternates should be engineering-approved, not chosen blindly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BOM quality affects production controls because ambiguous MPNs, missing DNP status, and uncontrolled alternates can change what parts are sourced and assembled. IPC benchmark releases track quality measures such as yields, defects, DPMO, rework, returns, supplier performance, and inspection\/test methods.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are preparing a turnkey build, compare your BOM against the broader <a href=\"\/ja\/blog\/pcba-quote-files\/\">PCBA\u898b\u7a4d\u3082\u308a\u7528\u30d5\u30a1\u30a4\u30eb\u306e\u30c1\u30a7\u30c3\u30af\u30ea\u30b9\u30c8<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is a CPL File in PCB Assembly?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A CPL file is a component placement list. It may also be called a pick-and-place file, centroid file, XY file, or placement file. It tells SMT programming where each component sits on the board.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Typical CPL fields include designator, X coordinate, Y coordinate, rotation, board side, and package. The designator is the bridge between the BOM and the CPL. If the BOM says U3 and the CPL says U4 for the same part, someone has to resolve the conflict.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"280\" src=\"https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/bom-and-cpl-designator-matching.webp\" alt=\"bom and cpl designator matching\" class=\"wp-image-9370\" srcset=\"https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/bom-and-cpl-designator-matching.webp 900w, https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/bom-and-cpl-designator-matching-300x93.webp 300w, https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/bom-and-cpl-designator-matching-768x239.webp 768w, https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/bom-and-cpl-designator-matching-18x6.webp 18w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Why rotation and polarity review matters<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Rotation conventions can vary between CAD exports and SMT programming. That does not mean CPL rotation is useless. It means the assembler should verify rotation-sensitive parts before production.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Check LEDs, diodes, IC pin 1, electrolytic capacitors, connectors, modules, and asymmetric packages. Silkscreen markings and assembly drawings help resolve unclear orientation. Would you rather catch that in review, or after reflow?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A CPL, centroid, XY, or pick-and-place file supports SMT setup by listing each component&#8217;s designator, X\/Y location, rotation, side, and package. That placement data lets the SMT program be checked against the BOM and assembly drawing before build.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For quote preparation, include the CPL with the files listed in the <a href=\"\/ja\/blog\/pcba-quote-files\/\">PCBA\u898b\u7a4d\u3082\u308a\u7528\u30d5\u30a1\u30a4\u30eb\u306e\u30c1\u30a7\u30c3\u30af\u30ea\u30b9\u30c8<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PCB Stackup Requirements for PCBA Quotes<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Stackup belongs to that bare-board construction discipline because layer order, dielectric thickness, copper, material, and impedance assumptions affect fabrication review.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A PCB stackup defines the physical layer construction of the board. It lists layer order, copper thickness, dielectric thickness, core and prepreg structure, material, Tg, finished thickness, and controlled-impedance targets where needed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Simple 2-layer prototypes may use a manufacturer\u2019s standard stackup. But multilayer, high-speed, RF, high-current, HDI, or controlled-impedance boards need clearer stackup data. Otherwise, the fabricator must infer construction details that affect cost and performance.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"760\" height=\"360\" src=\"https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/example-four-layer-pcb-stackup-cross-section.webp\" alt=\"example four layer pcb stackup cross section\" class=\"wp-image-9371\" srcset=\"https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/example-four-layer-pcb-stackup-cross-section.webp 760w, https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/example-four-layer-pcb-stackup-cross-section-300x142.webp 300w, https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/example-four-layer-pcb-stackup-cross-section-18x9.webp 18w\" sizes=\"auto, (max-width: 760px) 100vw, 760px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">When stackup is usually required<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Send stackup data for 4-layer and higher PCBs, controlled-impedance designs, high-speed digital boards, RF boards, antenna designs, high-current boards, and production builds that must be repeatable. Include target impedance, material, copper weight, layer order, and finished thickness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When stackup may be less critical<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For simple 2-layer prototypes, a supplier\u2019s standard material and thickness may be acceptable. Still, state any constraints. If board thickness, copper weight, finish, material, or impedance matters, don&#8217;t assume the supplier knows.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stackup data defines layer order, dielectric thickness, copper, material, finished thickness, and impedance assumptions before the PCB is fabricated and assembled. IPC-2221 covers generic PCB design principles, so stackup details should be treated as design-control data, not as an optional note for complex boards.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If stackup is part of the quote scope, include it alongside the files in the <a href=\"\/ja\/blog\/pcba-quote-files\/\">PCBA\u898b\u7a4d\u3082\u308a\u7528\u30d5\u30a1\u30a4\u30eb\u306e\u30c1\u30a7\u30c3\u30af\u30ea\u30b9\u30c8<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Do These Files Work Together in a PCBA Quote?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The files work together when they describe the same board revision and the same manufacturing scope. Gerber and drill files support PCB fabrication. BOM supports component sourcing. CPL supports SMT placement. Stackup supports construction review. Assembly drawings and test plans close the loop.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"980\" height=\"230\" src=\"https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/pcba-file-package-workflow-from-review-to-testing.webp\" alt=\"pcba file package workflow from review to testing\" class=\"wp-image-9372\" srcset=\"https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/pcba-file-package-workflow-from-review-to-testing.webp 980w, https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/pcba-file-package-workflow-from-review-to-testing-300x70.webp 300w, https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/pcba-file-package-workflow-from-review-to-testing-768x180.webp 768w, https:\/\/lead-pcb.com\/wp-content\/uploads\/2026\/07\/pcba-file-package-workflow-from-review-to-testing-18x4.webp 18w\" sizes=\"auto, (max-width: 980px) 100vw, 980px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">One missing file can change the quote. Missing CPL data can make SMT setup unclear. Missing stackup data can affect PCB cost and impedance review. Missing test requirements can make two suppliers quote different scopes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Quantity, lead time, surface finish, panelization, programming, coating, packaging, and compliance requirements can also affect pricing. The more clearly you define the scope, the easier it is to compare quotes fairly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A complete PCBA file package should define the manufacturing inputs that affect assembly outcomes before the supplier prices the build.

Gerber files define the board layers. The BOM defines components. The CPL defines placement. The stackup defines layer construction, materials, copper, dielectric thickness, and impedance assumptions. Many PCBA quote delays happen before production starts. Why? The factory may have board data, but not component data. Or it may have a BOM, but no placement file. Sometimes the Gerber, BOM, and CPL were exported from different design revisions. For a broader RFQ checklist, see our PCBA quote files checklist. This article explains what each file means and how to check the package before sending it to a supplier.
