Documents & Files Needed for PCBA Quotation

In the EMS industry, including PCB manufacturing, components sourcing, and PCBA assembly, salesmen often find that the documents and requirements given by buyers are not sufficient for PCBA quotation. Since the quotation requirements are not clearly stated, salesmen cannot provide the buyer with an accurate quotation in a timely manner, wasting time in the back-and-forth communication, and weakening the confidence of both parties in establishing cooperation.

So, what information do buyers need to provide in order to get a more complete and accurate quotation?

Let's talk about the documents and files needed for PCBs quotation.

RFQ for PCB (bare board) Fabrication

• Gerber files (including drilling layer file);
• Process files (manufacturing requirements, key parameters);
• Panelization files.

RFQ for BOM (bill of electronics component) purchase

• BOM details: include usage/quantity, manufacturer, manufacturer part number, component value, package, and other specifications.

RFQ for PCB Assembly

(mainly for SMT soldering processing)

• Centroid file (pick & place file);
• Silkscreen positioning drawing, which is necessary to clearly mark the polarity/direction of the components.

RFQ for one-stop turnkey EMS

(PCB manufacturing + BOM purchase + PCB Assembly)

• All the docs/files and information are listed as the above 3 items.
