Your current position：

Quality control

　　The leading quality management level is an important factor for the company to be recognized by customers. Since its establishment, the company has been focusing on product quality, and has established and improved six management systems, namely ISO9001, ISO14001, QC080000, IATF16949, ESD S20.20, ISO45001, and carried out comprehensive quality management activities by introducing the scientific and systematic management method of 6Sigma. From incoming material inspection in raw material procurement, to design quality planning in new product development, to first piece, line inspection, full inspection of finished products and sampling inspection in production process, the company will carry out quality management activities throughout the whole life cycle of products.

Through the application of WMS and MES systems, the company has realized the effective traceability and systematic control of products from single product, whole plate to electrostatic bag, small box and whole box, detected and managed all quality processes in production in real time, effectively prevented the variation of quality data in the manufacturing process in advance, quickly and accurately identified abnormal points and notified them in advance, and continuously improved the overall product yield. Meanwhile, by setting up QMS quality management system, the company has realized the digitization and systematization of quality activities such as first piece and inspection, and continuously promoted the quality optimization and promotion.

Quality Center Structure

Incoming inspection

Image Master Pro9

MASTER PRO 9 is a device suitable for the inspection of small lenses in mass production lines such as mobile phones, digital cameras and car lenses. It has the advantages of high measurement accuracy, high speed and easy operation. The equipment accuracy: on-axis is 1% and off-axis is 2%.

IR Spectrometer

XM 723H visible spectrophotometer with low stray light, high resolution single beam optical path structure, good stability, reproducibility, easy to operate, can complete the test more quickly, wavelength accuracy: ±1.0nm, reproducibility: 0.5nm.

RoHS Tester

HeLeeX E8 is a specialized RoHS testing instrument, and its core optical system integrates domestic and foreign EDXRF technology. The standard samples used in the instrument have authoritative third-party testing agency reports. Collimators with φ0.1mm to φ7mm can be configured to meet the test requirements of samples with different sizes.

Four-wire flying probe tester

XC V6 4-wire flying probe is a fully automatic FPC&PCB performance testing machine for hole copper problems. The resistance range is 0.4 mω -800 kω, the repeated test accuracy is 2 μm, the minimum test pad is 20μm, and the resolution is 1 μm.

Process monitoring
