PCB fabrication, one to 58 layers.
Multilayer, HDI and rigid-flex from the Bao’an floor that has been cutting cores since 2001 — IPC-6012 Class 2–3 acceptance, controlled impedance and 100% electrical test on every panel.
Quick parameters.
| Parameter | Capability |
|---|---|
| Layer count | 1–58 layers, with blind and buried vias |
| HDI builds | Sequential lamination and laser microvias — telecom and server board densities |
| Rigid-flex | Rigid-flex and hybrid stack-ups in the same shop |
| Surface finish | ENIG · HASL · OSP |
| Min trace / space | 0.075 mm |
| Controlled impedance | ±10%, TDR-verified where the net demands it |
| Acceptance class | IPC-6012 Class 2–3 |
| Inner copper | Standard and heavy-copper stacks for power boards |
| Prototype turnaround | From 24 hours on rush two-layer jobs |
| Volume lead time | 14–20 days |
| Electrical test | 100% electrical test plus flying probe — results attached per lot |
| MOQ | Prototype batches from 1–100 pcs; volume scales per stackup |
| Facility | Bao’an 45,000 m², 500+ people, owned by the HUAXING board business |
Specifications follow IPC-6012 and IPC-A-600. Final stackup and tolerances are confirmed on the engineering review — if a number worries you before money moves, we flag it there.
Design files in. DFM answers in 48 hours.
Your Gerbers are read by a board engineer, not an estimator. Layer stackup, the 0.075 mm trace and space floor, the ±10% impedance target, finish, copper weights and drill aspect — everything is weighed against our own rules before anything is priced.
Blocker items come back as a marked-up file with a suggested fix, so the review costs you one round trip instead of a month. Quotes land within 24–48 h, and first articles start from one board.
If the design lives at the edge — a high-density telecom backplane, a long-life industrial control board or an automotive module — expect the review to be stricter. The board shop cut power and energy product PCBs for the group’s own lines before it took customer programs, so the engineering tolerance for a heroic but unbuildable stackup is close to zero.
See the DFM checklistClass 3, shipped in volume.
Automotive and industrial boards run on the same lines that cut our first cores in 2001 — IATF 16949-audited processes, IPC Class 3 acceptance and a reliability lab behind every major release. When a stackup, a material or a tolerance worries you, you get an engineer on the phone, not a link to a price list. Ask for the cross-section from the last time someone pushed a Class 3 board: the backlog is the same one the group’s own product lines ship on.
