HAL SnPb
HAL SnPb (lead-tin) is nowadays allowed only in certain technology fields such as medicine and aeronautics. HAL SnPb has been replaced by HAL lead-free. If the surface finish is specified…
Scoring (also known as v-cut) is used for mechanical pre-separation of circuit boards. A V-shaped breaking line is formed in the circuit board with a precision cutting tool. Please observe the…
This section of the design aid provides you with all the information you need on the mechanical processing of PCBs.
Milling - lists the available milling cutter diameters and provides tips on the…
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…
