Our quality control procedures are conducted through following steps:


1. IQC: All in-coming materials & components would be inspected by IQC. Only qualified materials & components would be delivered to production line. Sufficient facility and manpower plus strict guidelines guarantee the fulfillment of the IQC.

2. IPQC: All products on the assembly line or subsidiary lines would be inspected & tested for function, safety and life cycles. Only qualified goods would be released and transferred to other departments.

3. OQC: All out-going goods would be inspected by QC according to AQL level. Only qualified goods would be sealed and transferred to the logistic department.

4. Testing lab: We have established a professional testing lab, which is equipped with modern facilities and experienced people. Products of each order would be withdrawn for function, safety, life cycle and other abnormal tests in this lab. For life testing, we would test a product for 300~500 cycles to check the life performance.

5. ISO commissioners: All ISO management and supervision is in the charge of the ISO team.
