3. 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)
4. raw materials

5. supplier management
Confirm the project - select or recommend supplier preliminary evaluation - send sample - Qualification - sample review - qualified - small batch delivery - Qualification - small batch approval - supplier comprehensive evaluation - join the list of qualified suppliers - regular supplier review - data archiving.
6. production process control
Advanced production and testing equipment, and give the maintenance of adequate training; orderly operation personnel in strict accordance with the SOP 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.) 5S, visual field management.
7. facility management
The high degree of recognition of the brand of equipment purchase in the industry (Disco, ASM, K&, S, JUNO etc), the equipment daily maintenance in place (daily maintenance, monthly maintenance, maintenance, Zhou Baoyang years); 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 MSA management.
8. customer complaint management process
Receive customer complaint - confirmation of complaints is true - the establishment of improvement team - temporary Countermeasures - reason analysis and confirmed -3 working sunrise 5D report -7 working full report - Sunrise improvement strategy selection to verify and implement permanent measures to verify and implement permanent measures to prevent recurrence - team summary.
