PCB Assembly Services in China
Cheerise Circuits provides PCB assembly and PCBA manufacturing support for prototypes, small batches, and production projects. We help customers coordinate bare PCB fabrication, BOM review, component sourcing, SMT assembly, inspection, testing, and delivery planning with one manufacturing partner.
PCB assembly is not only a placement process. A reliable PCBA project depends on clear engineering information before production starts, including Gerber files, BOM, CPL/pick-and-place data, assembly drawings, test requirements, component alternatives, and packaging expectations.
PCB Assembly Capabilities
- SMT assembly and mixed SMT/THT assembly support
- Component sourcing coordination based on customer BOM requirements
- Prototype, small-batch, and production-oriented PCBA support
- AOI, X-ray, flying probe, and functional test planning when applicable
- DFM communication for soldering risk, polarity, spacing, and manufacturability questions
What to Prepare for a PCBA RFQ
| Required File | Purpose |
|---|---|
| Gerber files | Define the bare PCB fabrication data. |
| BOM | Lists component part numbers, quantities, package types, and sourcing requirements. |
| CPL / pick-and-place file | Defines component coordinates, rotation, and placement side. |
| Assembly drawing | Clarifies polarity, special placement notes, and assembly requirements. |
| Testing requirements | Defines AOI, X-ray, flying probe, functional testing, or customer-specific checks. |
Inspection and Testing Strategy
Different inspection methods catch different risks. AOI is useful for visible assembly defects, X-ray can help inspect hidden solder joints under BGA or QFN packages, and flying probe testing helps verify electrical connectivity. The best PCBA quality plan depends on the failure modes that must be prevented from reaching the field.

PCB Assembly FAQ
Can Cheerise Circuits handle PCB fabrication and assembly together?
Yes. Cheerise Circuits supports PCB manufacturing and PCB assembly coordination so customers can manage fabrication, assembly, inspection, and delivery through one supplier.
What information is needed for a PCB assembly quote?
A complete PCBA RFQ should include Gerber files, BOM, CPL/pick-and-place file, assembly drawings, quantity, test requirements, and any component sourcing rules.
Is AOI enough for all PCB assembly inspection?
No. AOI is useful for visible defects, but hidden solder joints and electrical issues may require X-ray inspection, flying probe testing, or functional testing depending on the design.
