The SMB format is part of the Gerber group of formats, used as a standard in the fabrication of printed circuit boards (PCB). The group includes over 20 different formats, each defining different layers or significant data related to the production of such boards. SMB files describe the bottom solder mask of a PCB, which represents a polymer applied to copper traces for anti-oxidation purposes.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple SMB files as once.
