An STC file contains image data related to the top solder mask of a printed circuit board (PCB), and it is typically created using Eagle — a specialized piece of software for the PCB industry. STC is part of a larger group of extensions called Gerber, which is used as a standard in this industry. Other formats included in the group are SOL, CMP and DRD.
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 STC files as once.
