PCB Process: Line Design and Etching

After exposure, the PCB board needs to have the Mylar on the dry film stripped before entering the DES process. Of course, PCBs using wet film technology do not have the issue of Mylar and do not require its protection. Stripping Mylar Mylar stripping can be done manually or using automated equipment. Example of Mylar … Read more

Formulation of Semiconductor Photoresist Stripping Solution

Photoresist, also known as photoresist, is a non-conductive photosensitive material that transfers patterns from a photomask onto a wafer based on the principle of changing properties when exposed to light. After development, the unexposed photoresist needs to be washed away with a stripping solution to expose the substrate for subsequent etching. Currently, most stripping solutions … Read more
