Dear Customers,

PCBCart will be closed from Feb 4th to Feb 10th (GMT+8) for Spring Festival Holiday. Please schedule your orders earlier to ensure your PCBs & PCBAs to be manufactured and delivered as expected.

With the holidays approaching (from Jan 20th), we recommend those who want to submit order and have PCBs delivered before the Holiday reach us at sales@pcbcart.com to confirm the estimated shipping date first.

You can still get instant online quotes and submit orders during the holidays. Customer support will be available as soon as we're back on Feb 11th.

The Commonest Mistakes Engineers Tend to Make in PCB Design
