PCB Assembly Knowledge Base
PCBA guides for real RFQ work.
PCBA guides for Gerber files, BOM sourcing, prototype assembly, sample board review, and turnkey PCB assembly in China. New guides are based on the questions overseas PCBA buyers ask before quotation.

What Is Turnkey PCBA?
Understand what turnkey PCBA means, what steps it includes, when it helps overseas buyers, and how it differs from standalone PCB or SMT service.

How to Choose a PCBA Manufacturer in China
Choose a PCBA manufacturer by comparing file review, BOM sourcing, assembly and testing scope, revision control and engineering communication—not unit price alone. Ask for project-relevant evidence and clear responsibilities before production.

Turnkey vs Consigned PCB Assembly: Which Model Fits Your Project?
Turnkey coordinates fabrication, sourcing and assembly through the manufacturer. Consigned assembly uses customer-supplied components; partial consignment splits the BOM between buyer and manufacturer. Choose by the parts you own, the sourcing control you need and the purchasing work you can manage.
