What the factory can do

SMT & assembly

Two Yamaha lines, 68,000 CPH combined. Reflow in nitrogen, AOI on every board, X-ray for BGA lots. Boards are washed and dried in-line; no-clean or water-wash to your call.

Testing

ICT, flying probe and functional test jigs built in-house. Test coverage is agreed with you before the first run, and the pass/fail log ships with every order.

Components

We buy direct from franchised distributors or from you as consignment. Every reel is checked against the datasheet and the date code is recorded per lot.

Packing & shipping

ESD bags, moisture-barrier bags with desiccant and humidity cards, and export cartons. We ship DDP or FOB Shenzhen by air or sea, 3–5 days to most ports.

Certifications: ISO 9001:2015, ISO 14001:2015, RoHS and REACH compliance on all standard materials. UL-recognised PCBs available on request.

Company

BTN Electronics was founded in Shenzhen in 2011 as a 14-person assembly shop. Today the plant covers 12,000 m² with 320 staff across three shifts, and more than 60% of output ships to customers in Europe and North America. Our customers are mostly industrial controls, lighting and home-appliance brands ordering 1,000–50,000 units per run. We hold a 30-day buffer stock of common passives so a repeat order can start the same week you confirm it.
