Contract Manufacturing in China

Contract manufacturing in China — PCB assembly and box-build by P&A International

Contract Manufacturing in China for OEMs

A single engineering partner for manufacturing in China. P&A International engineers, prototypes and delivers turnkey contract manufacturing — PCB fabrication, PCB assembly (PCBA), box-build and system integration — managed end-to-end to your BOM, test and compliance requirement.

As an engineering-led contract manufacturer founded as an engineering consultancy, we assign one dedicated engineer to your project from DFM review to qualified NPI samples in 10–15 working days, then scale into volume through our vetted partner-factory network, where every supplier is ISO 9000 certified or better.

PCB assembly (PCBA)

SMT, through-hole and mixed-technology assembly with AOI and test, to IPC-A-610 class.

Box-build and system integration

Box-build & integration

Enclosure assembly, cable integration, firmware load, labelling and packaging — ready to ship.

PCB fabrication panels

PCB fabrication

Bare-board fabrication to your stackup, materials and class, ready for assembly.

Electronics assembly and test line

Test, inspection & NPI

AOI, ICT, flying-probe and functional test, plus new-product introduction.

We also deliver the flexible PCBs, custom power supplies and wiring harnesses that go into your product, through the same engineering team and partner network.

Why engineers & buyers choose PA

For design engineers

A true engineering partner — one dedicated engineer, DFM/DFT review, the right assembly and test process for your board, and NPI that de-risks the transfer to volume. We build to your design and standards.

For purchasing

Low-risk scalability — predictable 10–15-day NPI, flexible MOQ from prototype to production, target-cost DFM, a single point of contact, and a vetted ISO 9000+ partner network managed end-to-end by P&A.

3 easy steps to get started

1

Send us your package

Send Gerbers, BOM and assembly files (or a sample). One dedicated engineer reviews it and confirms the build with you.

2

Proposed build & quote

You receive a proposed build and indicative pricing — typically within 48 hours — to review and refine together.

3

NPI, test & production

Qualified NPI samples with full test data in 10–15 working days; on approval we scale into volume through our partner network.

Applications

Industrial & automation · medical & instrumentation · networking & telecoms · consumer electronics · IoT & embedded · energy & storage · automotive & e-mobility.

See our main electronics contract manufacturing page, plus flexible PCB, custom power supplies and wiring harness & cable assembly.

Scoping your manufacturing project

A clear scope gets you a faster, more accurate quote. A few decisions shape every build:

Scope PCB fabrication, PCB assembly (PCBA), or full turnkey box-build — tell us where you want us to start and stop.
Assembly SMT, through-hole or mixed; fine-pitch, BGA and QFN need the right stencil, profile and inspection.
Test AOI as standard; add ICT, flying-probe or functional test to match volume and reliability needs.
Class IPC-A-610 Class 2 for general products, Class 3 for high-reliability; ISO 13485 for medical.
Volume Prototype, NPI and production all supported — share annual volume so we right-size the build and MOQ.

What to send us for a fast, accurate quote

The more of this you can share, the quicker we can return a proposed build and price:

  • Bare-board Gerbers / fabrication drawing and stackup
  • Bill of materials (BOM) with part numbers and approved alternates
  • Assembly drawing, pick-and-place / centroid file and panelisation
  • SMT, through-hole or mixed; single- or double-sided placement
  • Box-build / system scope — enclosure, cables, labelling, packaging
  • Test requirement (AOI / ICT / flying-probe / functional) and IPC-A-610 class
  • Conformal coating, potting or special handling, and any compliance marking
  • Target cost, prototype quantity and annual volume or call-off pattern

Working from an existing product or a competitor build is fine — our engineer will reverse-engineer it or propose an improved, manufacturable design.

    Frequently asked questions

    What does your electronics contract manufacturing cover?
    The full chain — PCB fabrication, PCB assembly (PCBA), box-build and system integration, plus inspection and test — managed end-to-end by one dedicated engineer through our vetted partner-factory network.
    Do you handle low-volume prototypes and NPI as well as production?
    Yes — prototypes, new-product introduction (NPI) and full production. Qualified samples with test data typically in 10-15 working days, then we scale into volume.
    Which assembly types and component packages can you place?
    SMT, through-hole and mixed-technology, including fine-pitch, BGA and QFN, with the stencil, reflow profile and inspection matched to the board.
    What test and inspection do you offer?
    AOI as standard, plus ICT, flying-probe, functional test and burn-in as needed, built to IPC-A-610 Class 2 or 3. Every supplier in our network is ISO 9000 certified or better.
    What are prototype lead times and minimum order quantities?
    Qualified NPI samples with full test data typically in 10-15 working days. Volumes scale through our vetted partner-factory network; share your annual volume and we will confirm an MOQ with the quote.
