STS to RIFF 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 RIFF files?

The Resource Interchange File Format RIFF is a structured multimedia container format developed through a collaboration between Microsoft and IBM in 1991. As an adaptation of the Electronic Arts Interchange File Format (IFF), RIFF implements a tagged chunk architecture where each data segment contains a 4-character identifier, 32-bit size field, and payload data. This design enables hierarchical organization of heterogeneous multimedia streams while maintaining platform-independent data representation through strict little-endian byte ordering.
