Attention:
Please specify component holes ≤ 0.4mm with your order! Component holes ≤ 0.6mm must be manufactured with a chemical surface, otherwise these holes will be filled with tin during the…

Attention:
Please always specify the final hole diameter within the PCB data. Hole diameter ≥ 0.5mm will be final diameters. Component holes ≤ 0.4mm need to be specified in the order! Component…
A unique differentiation in your data between plated-through holes (PTH) and non plated- through holes (npth) is of fundamental importance!
This means that you must, additional to your Gerber…

Pitch vs. Pad width
If the minimum values for solder-stop clearance (50μm) and solder-stop bridge (100μm) are undercut, the complete solder-stop bridge is omitted (so-called gang mask opening or…
Thanks to the excellent capacity utilisation of our pool production for 2-layers 1.0mm, the production time can be reduced by 1WD . The express options for this service can be offered at even lower…
Calculation tip for defined Z0 as well as ZDiff
If, in addition to a differential impedance (ZDiff), you also need a defined Z0, proceed as follows:
Calculate Z0 as normal Microstrip, until you…
