A board is only a product once the parts are on it. Xianglong Circuit offers turnkey PCB assembly: we fabricate the bare board, source components, stencil, place, reflow, inspect and test - so you send Gerber, BOM and pick-and-place files and receive finished, tested assemblies in export packaging.
Our SMT lines in Dongguan place 0201 passives, 0.25 mm-pitch BGA and QFN packages, and fine-pitch connectors at high volume, with double-sided reflow, through-hole wave and selective soldering for mixed-technology boards. Every batch passes AOI, with X-ray on BGA families and flying probe or functional test to your test spec; a retained sample is archived for 12 months so field questions can be answered with real hardware, not memory.
Component sourcing runs through franchised distribution with anti-counterfeit checks, and shortages are flagged with alternates before they stop the line. MOQ starts from 5 pieces - deliberately friendly to hardware startups and pilot runs - while the same lines run 100K+ monthly for industrial customers.
Send Gerber, BOM and centroid files for a line-by-line quotation and DFM report within 24 hours. Quick-turn assemblies ship in 3-5 working days; standard volume in 10-15 days.

Gerber or ODB++ for the bare board, a BOM with manufacturer part numbers and quantities, and centroid (pick-and-place) data. With those three we return a complete board + parts + assembly quotation and DFM report within 24 hours.
Turnkey: we buy everything and ship finished boards. Partial: you supply ICs, we handle passives and assembly. Consigned: you ship all parts, we assemble. Most startups choose turnkey; customers with locked-down or legacy ICs choose partial.
Sourcing runs through franchised distribution, and every BOM line is checked for stock, lifecycle and alternates before quoting. If a part is short or EOL, you get proposed substitutes with datasheets before the line stops.
Yes. Flying probe for prototypes, bed-of-nails or functional fixtures for volume, to your test plan. Test development can start from your firmware team's checklist or a full test specification.
