Substrate Options for PCB Laser Etching

To stay ahead of the competition with RF/Microwave, wireless, IoT, and other microelectronics, engineers and manufacturing teams must continuously evaluate the best new methods to produce efficient circuits. While the list of potential substrate materials is long, this paper details capabilities offered with the LPKF ProtoLaser S4 and ProtoLaser U4 models on a handful of top choices, each popular for different reasons.
