Factory · Shenzhen, China
Six steps. One roof.
SMT, assembly, functional test, burn-in, outgoing QC and packaging — the entire build runs in our Shenzhen facility, so the people who answer your RFQ are the people who make the board.

Manufacturing Flow
How a board moves through the line
Six fixed stages, one per unit, every board serialized. There is no step between reflow and the shipping carton that isn’t accountable.
SMT
Solder paste printing, placement and reflow on automated lines; profiles verified per batch, wide-temperature bins used where the design calls for them.
Assembly
Through-hole parts, heatsinks, connectors and mechanicals fitted at ESD-protected stations, each board tracked by serial label.
Functional Test
Every unit runs the model’s test plan: CPU and memory, displays, COM and LAN ports, USB, power rails and watchdog.
Burn-In
Production batches are aged under load on 24/7 cycles, so early-life failures surface in our plant rather than on your line.
Outgoing QC
Final inspection: appearance, configuration against the order, BIOS settings and packing readiness.
Packaging
Bare boards ship in ESD bags with desiccant; retail boxes, custom labels and batch documents on request.
Process Discipline
What we control, batch by batch
Manufacturing is a set of windows, not habits: reflow curves, humidity, ESD discipline and test coverage are checked against records, per shift and per batch. If a field question comes in about a board shipped six months ago, the answer starts with its serial and its build record.
Components bought to the BOM with long-life industrial grades where the design requires wide temperature or 24/7 duty.
Batch and serial records follow each board from the reel to the pallet.
Every board carries its test record; acceptance criteria are the ones on the spec sheet you quoted against.
Bare boards carry no battery restrictions, so courier, air and sea all stay simple.
Line Control Points
What the line checks
Equipment is described generically on purpose — the process is what we vouch for, not a brand name on a machine.
Wrist straps, mats and humidity logging at every handling station.
Temperature curves verified per batch against the paste and board specification.
The first unit of each build is fully tested before the line continues.
Each serial links to its build batch, test results and packing date.
Batch aging on 24/7 cycles to move early-life failures into our plant.
Date-coded components with oldest-stock-first rotation in the stores.
Post-solder cleaning and visual checks per board, not per pallet.
ESD-safe packaging with no battery restrictions — courier, air or sea.
