* Production lines are equipped with high-end , high precision and high yield machine.
* Quality inspection and control are carried out in each process to avoid defective products go out.
* Professional engineers l for the whole process sampling inspection.

① Sticking board: check if SMT mounting position of components are correct, greatly reduce SMT trial production time and waste of components, effectively ensure the quality of SMT.
② Intelligent first-sample tester: wrong components, ,reverse polarity, reverse direction etc., compared with visual inspection, accuracy is higher 50%.
③ SPI-fully automatic 3D solder paste thickness measuring intrument: check printing quality problems, such as missing print, less tin, more tin, tin bridge, tin offset, poor shape, surface stuff etc.
④ AOI：check short ,miss, polarity, offset, wrong parts.
⑤ Xray: Open-circuit and short-circuit inspection of BGA, QFN and other issues.
