FAQ
Can you work according to my time zone?
Yes.
Do you only design PCB, or do you also guide the manufacturing process?
Yes
You mentioned that you provide initial PCB validation. Could you explain this in more detail?
Yes. Initial PCB validation means verifying that the basic functions of the board work as expected after manufacturing. This typically includes power-up checks, basic signal verification, communication interface testing (such as SPI, UART, CAN), and identifying any obvious design or assembly issues.

Some friend of mine has recommended Yanxia for me to review my manufactured PCBs before sending it so I can save money and time cause he's Chinese that gave him an advantage as JLCPCB factory is there and that will be much better like one stop shop for all PCB services. I 've found him very helpful and delivered exactly on the time. thanks Yanxia.

I would give Yanxia 6 stars if I could. I'm working on an extremely low-power project, and Yanxia knocked the delivery out of the park. The calculations, the delivery, and the clarity were all amazing. I'm not an electrical engineer but Yanxia was very patient and explained everything to me. I cannot wait to work with Yanxia again.
