The shippings costs are calculated by our Online-Calculator during the order process! If you would like to guess the PCB weight, the rule of thumb is: 0.3m² (e.g. 30 PCBs 100x100mm) 2 layers FR4…
On Wednesday, August 12th 2020 we carry out an extension of the computer center.
From 7pm to approx. 11pm our PCB calculator is not available.
We apologize for the inconvenience caused.
