STS to AVIF Conversion: FAQ

What are STS files?

An STS file contains a two-dimensional vector representation of the bottom solder mask which makes up a printed circuit board (PCB), and it is most likely created and processed with Eagle software. STS is part of a larger family of extensions called Gerber, which represent the de facto standard used in the PCB industry. Gerber files describe various aspects of electronic boards, including copper layers, solder masks, electrical connections, drilling or milling data. Similar formats include SOL, STC and PLC.

What are AVIF files?
