Questions & Answers
GTS files: Frequently Asked Questions
What are GTS files?
The GTS file format is a file extension used for Gerber Top Solder mask files. Gerber files are used in the PCB (printed circuit board) manufacturing process and provide information to the manufacturer on the placement of copper traces, vias, drill files, and various other aspects involved in designing a PCB. The Top Solder Mask file contains information about the locations where solder mask will be printed on the top surface of the PCB to prevent solder bridges from forming between adjacent traces during the soldering process. Gerber files are typically generated using CAD software that is capable of exporting files in the Gerber format.
