ProtoLaser vs. ProtoMat vs. Classical Etching

The application report describes three different methods of producing a circuit board prototype of a microstrip bandpass filter and compares the results with each other.

In two methods, the circuit board is structured by mechanically removing the copper from the base material by laser ablation with a ProtoLaser U4 and by milling with a ProtoMat S103. The third method is the classical chemical method of etching the copper. It is also the comparison between the fast and simple in-house procedures laser ablation and milling compared to the classic printed circuit board production technique.
