1. Quality management system certifications

Huixin continues to promote management innovation, strictly comparing and referring to domestic and foreign industry leading quality control standards for internal management. Importing IATF16949:2016 quality management system standards , ISO9001:2015, to control the whole process of product design and development, supplier management, raw material selection, production process control, product inspection and testing, customer service, to meet market and customer needs.

2. Key quality control points

Material income (material test) - dicing process (minimum margin) - loading process (push crystal dispensing) - wire (wire pull, solder ball ball thrust arc height, thickness measurement check ball rot silicon layer) - encapsulation (dislocation) - flash - (immersion tin coating thickness, harmful the material, easy welding test) - cutting molding (standing height) - test print tape (tape tension) - packaging (factory inspection)

3. Production process control
Advanced production and testing equipment, and give the maintenance of adequate training; orderly operation personnel in strict operation, the key quality control points, use SPC tools to monitor the stability of the semiconductor industry, the working environment is maintained (temperature and humidity, cleanliness, illumination, ESD, etc.) , visual field management.

4. Facility management

The equipment daily maintenance in place (daily maintenance, monthly maintenance, yearly maintenance); every month to repair equipment maintenance situation, summarize the situation analysis, determine the key for maintenance, preventive maintenance plan and implementation; the key components of spare parts management; mold, tool (blade, nozzle, ejector, mold, molding tool, test piece etc.) life of vulnerable parts of control; preparation of calibration plan and implementation; an important measurement system for management.

5. Customer complaint management process

Receive customer complaint - confirmation of complaints is true - the establishment of improvement team - temporary countermeasures - reason analysis and confirmed -3~7working day 8D report - strategy selection to verify and implement measures - to verify and implement measures to prevent recurrence - team summary.
