Every order gets a DFM review within 1 business day — four checks before anything is purchased: pad solderability, stencil apertures, panelization, and BOM risk (EOL and alternate parts). The average PCB re-spin costs about $28,000 plus 2–4 weeks of schedule, and 90% of companies have shipped a product late. Both problems are cheapest to stop before a stencil is cut.
Mini case: a 6-layer industrial controller arrived with a connector whose BOM line was flagged EOL by two franchises. Our sourcing team proposed a pin-compatible alternate, the customer qualified it in 3 days, and the build held its 5-day slot.
How we quote >How we work
Each step has a named owner on our side and one thing to confirm on yours.
Upload Gerber or ODB++, BOM, pick-and-place data and assembly notes. A priced quote with DFM feedback returns within 1 working day.
Your part: confirm quantities and service level — turnkey or consignment.
Turnkey parts are purchased through authorized channels with EOL screening; passives carry a 5–10% overage. Consignment kits are verified line-by-line against your BOM on arrival.
Your part: approve any proposed alternates.
Paste printing with 100% inline SPI, placement at ±0.025 mm, reflow at a programmed 240–255 °C peak. Wave and selective soldering cover the through-hole side.
Your part: confirm the acceptance class — Class 2 default, Class 3 on request.
Flying probe for prototypes, ICT fixtures for volume, then FCT to your bench spec. Every board has passed 100% AOI, and every BGA/QFN has passed X-ray before this gate.
Your part: supply the FCT procedure and any fixtures.
A CoC travels with every shipment, backed by batch and date-code traceability records. DHL/FedEx/UPS reach EU and US doors in 3–5 days; EXW/FOB/DAP/DDP on request.
Your part: confirm the Incoterm and courier account.
Repeat orders restart in 5–10 working days with a fresh BOM health check each run; engineering changes get a delta quote in the same week.
Your part: flag EOL notices or spec changes as early as you can.
Industries
Four industries, four numbers we design against.
OEMs run 0 PPM programs with realistic supplier targets of 25–60 PPM. We build to IPC-A-610 Class 3 on request and ship PPAP Level 1–3 documentation packages with batch traceability.
Quality systems expect records kept 10+ years and UDI-ready traceability. We provide lot-level traceability, a CoC per shipment, and Class 3 acceptance where your device file requires it.
Equipment serves 15–25 years while some ICs go EOL in under 10 — often without a PCN notice. Our BOM health check flags those parts before you commit; last-time-buy windows typically run 6–12 months.
Launching 9–12 months late costs about 50% of expected profit. Turnkey prototypes in 5–7 working days, with 72-hour expedite for simple boards, keep design-validation loops inside two weeks.
Quality
IPC-A-610 Class 2 as standard and Class 3 on request; 100% AOI after reflow and 100% X-ray on BGA/QFN; an ESD S20.20 program across the floor and MSD dry cabinets below 5% RH.
Certified to ISO 9001:2015 and ISO 14001:2015. Automotive and medical programs run on IATF 16949-aligned workflows (PPAP Level 1–3) and ISO 13485-aligned documentation (DHR style) — ask for copies of certificates.
The floor
Five zones on one floor — SMT, DIP, conformal coating, box-build assembly and a test lab — at 107 National Highway, Xixiang Street. Boards never leave the building between processes, so nothing is re-qualified by a second vendor.
Before you commit
The things buyers usually email us about — stated here so your first quote needs no round-trip.
Gerber or ODB++ for the board, an Excel BOM with manufacturer part numbers, pick-and-place coordinates and any assembly notes.
MOQ is 1 pc — prototypes and production share it. Comfortable range from 1 to 100,000+ pcs across 300+ new part numbers a year.
Quote with DFM notes in 1 working day; turnkey prototypes in 5–7 working days; typical production builds in 15–20 days.
NDA by default — signed before your files change hands. Boards never leave our building between processes, so designs stay in one pair of hands.
A Certificate of Conformance with every shipment, batch and date-code traceability records, PPAP Level 1–3 documentation on request.
DHL, FedEx and UPS reach EU and US doors in 3–5 days; EXW, FOB, DAP and DDP terms under Incoterms 2020.
Sourcing network
When consignment does not cover your BOM, parts come through authorized global distribution — these are the channels we buy through, with full traceability back to the franchise.
