Description
Incoming Control/ IQC
All external materials must be verified before going to warehouse. We have strict verifying procedures and working instructions to control the incoming. And, there have precise inspection equipment to judge whether the verified material is good or not. Materials are managed by a computer system. When one material gets close to expiry date, the system will issue a warning, which ensures that materials are used up before expiry or verified before use.
Fabrication Control
Right manufacturing instruction (MI), total equipment management and maintenance, strict WIP inspection, monitoring and working instructions, these make production process well controlled. Control plan, various precise inspection equipments and WIP inspection instructions guarantee that semi-products and final products reach requirements of customers.
Inspection and testing
PCBs must go through the open and short test and visual inspection after passed relative physical tests. Our test equipments include AOI Testing, X-ray inspection and In-Circuit Testing for finished PCB assembly.
Approval before delivery
FQA inspect the products by sampling. Before packing and delivery, FQA must 100% audit every shipment for production number, customer code, quantity, delivery address and packing list etc.
