PCB Dimension
We accept PCBs within these dimensions for our prototype service, contact our support if your design does not meet these criteria.
min. dimension
>10 mm / >0.4 in
max. size
400 x 400 mm / 15.74 in x 15.74
Surface Finish
We use Electroless Nickel Immersion Gold (ENIG) as surface finish for our 2 Layer HD PCBs, this surface finish offers good surface planarity and high oxidation resistance.

Silkscreen
We use Peters SD2692 ink for the silkscreen on our PCBs and apply it using the direct printing method. The smallest supported width is 150 µm / 6 mil, all silkscreen features with a width less of that will be adjusted. Silkscreen printed on pads is not supported, we use openings in the soldermask as reference to cut away / remove the silkscreen in the affected area. Do not use the silkscreen to produce large fillings, designs which cover more than 25% per PCB side will be rejected.

min. spacing silkscreen / edge

Soldermask
We use high-quality Peters Elpemer AS 2467 SM-DG green soldermask which is well suited for the ENIG finish. Please refer to our soldermask specification for the electrical properties of the soldermask.
