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.
