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.

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.

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.

Class 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.
