Dear Customers

PCBCart will have the official holidays since Jan. 24th through Feb. 3rd for Chinese Lunar New Year. Please schedule your order earlier (about half a month earlier for bare PCB orders and start assembly orders from now on) to ensure that the products could be manufactured and delivered on time before our holiday. If the orders with delivery date scheduled around those days need to be delivered before holiday, please contact us.


PCBCart has been implementing circuit boards fabrication procedures stringently conforming to IPC-compliant guidelines and regulations in order to ensure their highest reliability and best performance in our clients' projects.
