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.
Question: What is the standard format you accept?
Answer: We accept standard gerber format file.
Question: Do you have MOQ requirements?
Answer: Because PCB is customized products, so we do have MOQ requirements. But the MOQ rquirement is not strict and it differs from case to case.
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
Quesiont: What is ENIG?
Answer: ENIG (Electroless Nickel Immersion Gold) is a surface plating that is applied over the copper pads on a Printed Circuit Board to protect them from corrosion and other abnormalities. Initially, the copper pad is covered by a Nickel (Ni) layer followed by a thin immersion Gold (Au) layer. ENIG provides good oxidation resistance, excellent surface planarity and allows for easy soldering which results in excellent electrical performance of the PCB board.
ENIG is RoHS compliant is therefore one of the most used PCB surface finishes even though it is more complex and expensive when compared to other PCB plating process like HASL.
ENIG is a two-layer metallic coating – Nickle is the barrier to the copper pad and is also the materials to which the components are soldered. Gold on the other hand protects the Nickle during storage and also provides low contact resistance. Typical Nickle thickness varies from 4 – 7 µm and Gold thickness varies from 0.05 – 0 23 µm. ENIG requires a processing temperature of around 80 °C.
