FAQ:
Question: What is the most common quality issue for this kinf of pcb?
Answer: 1) Copper burr in half holes
2) Oxidation in half holes
Question: What is the difference between your two factories?
Answer: The HuiZhou factory mainly produce sample and small batch pcbs. The JiangXi factory has more roboticized equipments, so it prefers big batch production.
Question: What is your shipping term?
Answer: EX WORK, FCA SHENZHEN, FOB SHENZHEN ,FOB HONGKONG, or FCA Customer's City, it depends on customers demand. But we prefer EX WORK and FCA SHENZHEN.
Question: How can you guarantee the quality of your products?
Answer: About electricty function, we will 100% test it through flying tester or fixture test. About the surface, we have IPQC and FQC and FQA to make sure the products with flaw do not flow to customer's side. We also do microsection and thermal shock to make sure the reliability of our products.
