FAQ

Q: What customization options do you offer?

A: We support full customization, including PCB layer count (2–8 layers), material (FR‑4, aluminum, CEM1), solder mask color, component selection, firmware programming, and communication protocols (Wi‑Fi, Bluetooth, CAN). We also optimize for size, power efficiency, and environmental ratings (IP54/IP65)[20].

Q: What testing standards do you follow?

A: All PCBA undergo 100% AOI (Automated Optical Inspection), X‑ray for BGA/QFN components, and functional testing (FCT) per customer specs. Additional tests include EMC/EMI, dust/water resistance (IP54/IP65), and high‑temperature aging to ensure reliability[20].
