What is temporary solder mask?

Temporary solder mask, also known as peelable solder mask or removable solder mask, is a type of masking material used in the electronics manufacturing process. Its primary purpose is to protect specific areas of a printed circuit board (PCB) during the soldering process, while allowing other areas to be exposed for soldering. After the soldering process is complete, temporary solder mask can be easily removed by peeling or washing it off (depending on the type of mask), leaving the protected areas clean and free of any excess solder. This allows for easy access to the designated areas for subsequent assembly steps or inspections.
