Dear Engineers. I am looking for a etching simulation software for mask making in PCB Etching Process. There are so many complex patterns I need to form on the PCB. For the simple patterns, I already set up compensation rules. But for the comlex patterns, It was very hard to make a ccmpensation rule. Does anyone have good idea or good simulation tool for this? Thank you in advance.
