A factory that
still reads drawings.

Founded in Sanchong, New Taipei in 1988. We are a mid-sized connector and switch maker with our own tooling, stamping, plating and assembly — which is another way of saying we can change a dimension without waiting for three suppliers to agree.

OP-U31TC · WATERPROOF TYPE-C SERIES

Since 1988

Thirty-eight years of
small, precise parts.

We started with D-SUB connectors and DIP switches for the local electronics industry. As the industry moved — to USB, to fine-pitch board-to-board, to waterproof assemblies — the tooling changed, the discipline did not.

Today the catalog covers eight product lines and more than 15,000 part numbers: terminals, housings, wafer connectors, USB and Type-C, RF, card sockets, modular jacks, switches and cable assemblies. Most of them share the same engineering team and the same plating line.

If a standard part almost fits, we would rather modify it than sell you something that does not.

04 — PROCESS

Five steps, one roof.

Everything that decides the reliability of a connector happens inside these five steps. Keeping them in-house is how we control lead time and how we can answer "why did it fail" with a real answer.

01 · Tooling

Progressive dies and injection moulds designed and maintained in-house. Drawing changes do not queue behind an outside supplier.

02 · Stamping & moulding

High-speed presses and insert moulding; first-article inspection on every tool change.

03 · Plating

Reel-to-reel gold and tin plating. Plating thickness is the number one cause of field failures — we measure it, batch by batch.

04 · Assembly

Automatic and semi-automatic assembly, with in-line electrical and dimensional checks.

05 · Inspection & packing

100% electrical test on finished switches and connectors, AQL sampling on mechanical characteristics, then taped or tubed packaging to your line format.

Quality policy

ISO 9001 based process control. Complaints are answered with a root cause, not a replacement shipment alone.
