Factory · Shenzhen, China

Six steps.
One roof.

SMT, reflow, assembly, functional test, burn-in and packing run in one Shenzhen building. The people who answer your RFQ are the people who make the board.

01 · The flow

How a board moves through the line.

Six fixed stages, one per unit, every board serialized. There is no step between solder paste and the shipping carton that is not accountable.

Line control points

Stage 01 / first unit tested

SMT

Solder paste printing and placement on automated lines. The first unit of each build is tested before the line continues.

Stage 02 / curve per batch

Reflow

Temperature curves verified per batch against the paste and board specification.

Stage 03 / ESD stations

Assembly

Through-hole parts, heatsinks, connectors and mechanicals fitted at ESD-protected stations.

Stage 04 / every unit

Test

Model test plan: CPU, memory, displays, COM, LAN, USB, power rails and watchdog.

Stage 05 / every batch

Burn-in

Batches aged under load on 24/7 cycles, so early-life failures surface in our plant.

Stage 06 / every carton

Packing

Outgoing QC, ESD bag with desiccant, labels and batch documents for the carton.

02 · On the floor

Six stages, photographed where they happen.

03 · Line control

What the line checks.

Equipment is described generically on purpose. The process is what we vouch for, not a brand name on a machine.

See the quality program

Six control points

Recorded per batch, per serial

Each serial links to its build batch, test results and packing date. Batch and serial records follow the board from the reel to the pallet.

05 · Warehouse and dispatch

Stock, kitting and export packing under the same roof.

Reels and finished boards move from the line into an ESD-safe store, then into kitted, labelled export cartons. The dispatch desk works from the same batch record as the line.

01ESD store

Reels and finished boards are held in antistatic shelving next to the line, date-coded and rotated oldest first.

02Kitting

Model, accessories and paperwork are kitted per order before the carton is sealed.

03Export packing

Boards ship in ESD bags and foam, with the packing list and batch record matched to the invoice.
