What files do you need to evaluate a PCBA project?

Send Gerber files (RS-274X or ODB++), a BOM with manufacturer part numbers, the pick-and-place (centroid) file and an assembly drawing. If you need functional testing, add the test specification, firmware and any test fixture requirements so FCT can be planned before production.

Do you support low-volume prototypes as well as mass production?

Yes. The same SMT lines handle engineering prototypes, pilot runs and volume production. Small batches carry a higher unit cost because stencil, line setup and component reel minimums are spread across fewer boards; our engineers advise on panelization and alternate parts to reduce that cost.

How do you control PCBA quality?

Quality is controlled in a closed loop: incoming material inspection, 3D SPI after solder paste printing, AOI after reflow, X-ray inspection for BGA and hidden joints, and functional testing before packing. Workmanship follows IPC-A-610 Class 2 by default, with Class 3 available on request, and the process targets a first-pass yield of 98.5% or higher.

Can you source the electronic components for us?

Yes. We offer full turnkey service where we procure all components through long-term supply partners, partial turnkey where you consign critical parts, and consignment assembly where you supply all materials.

Can overseas buyers audit the factory before ordering?

Yes. Buyers can schedule an on-site audit at our Shenzhen facility or a live video audit covering material storage, SMT lines, inspection stations and traceability records.

Industrial Ecosystem Dominance

The Shenzhen Advantage in Multi-Country Certification PCBA

Navigating complex international regulatory barriers requires more than surface-mount machines. It demands tight integration with certified component supply lines, localized testing laboratories, and rapid engineering iterations.

Hyper-Localized Sourcing Ecosystem

Located in Longgang District, Shenzhen, our facility operates within a 2-hour radius of the world’s most comprehensive supply matrix for UL94-V0 rated laminates, certified passives, and original semiconductor channels. This ecosystem eliminates weeks of component transit delays while ensuring genuine traceability certificates (CoC) for regulatory verification.

Integrated Pre-Compliance Verification

Partnering directly with accredited CNAS/CMA testing chambers in Shenzhen, our engineering directors conduct rigorous pre-compliance evaluations—including conducted and radiated emissions (CISPR 32 / FCC Part 15B), dielectric breakdown tests, and ESD immunity (IEC 61000-4-2)—long before shipping prototypes to overseas testing houses.

DFM for Global Regulatory Compliance

Design for Manufacturing (DFM) must balance both production yield and regulatory physics. Our 20+ year engineering veterans examine creepage and clearance distances, high-speed trace return paths, grounding vias, and thermal dissipation metrics directly within Gerber and BOM files to prevent certification failure redesign cycles.
