FAQ
Automatische Übersetzung
Können Sie gemäß meiner Zeitzone arbeiten?
Ja.
Entwirfst du nur PCB oder leitest du auch den Herstellungsprozess?
Ja
Du hast erwähnt, dass du eine erste PCB-Validierung anbietest. Kannst du das genauer erklären?
Ja. Die erste PCB-Validierung bedeutet, zu überprüfen, ob die Grundfunktionen des Boards nach der Herstellung wie erwartet funktionieren. Dazu gehören in der Regel Stromversorgungstests, grundlegende Signalkontrolle, Kommunikationstest (wie SPI, UART, CAN) und die Erkennung offensichtlicher Design- oder Montageprobleme.

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.
