G10 FR4 Machining

Some suppliers stamp out parts from G10 FR4 (Mil-I-24768/27) and other materials. Others use lasers or water-jets. We use only high-speed, multi-head CNC machines running “dry,” meaning that no CNC fluids are used to cool the machinery. We believe this process maintains the full insulating value of the material, while providing cleaner edges, finishes and tighter compliance with specifications.

Our facility can machine G10/FR4 into a wide range of shapes and sizes with tight turnarounds. Our quality control systems and procedures are certified to meet ISO 9001: 2008 standards. These mandate certificates of compliance for all raw materials. So what you specify is what you get. They also help ensure that your parts will consistently meet the highest quality standards across any run-size.

We have the capability to machine G10 and FR4 materials with quick turns and outstanding quality. Our CNC machining of G10/FR4 parts is produced in a state of the art facility with modern tooling and measurement equipment. Machining G10/FR4 materials takes very precise and accurate measuring and quality inspection. There are many processes required for G10/FR4 machining that take experience, meticulous quality control and examination. The very first and most important part of producing G10/FR4 into fabricated parts is to start with a high quality G10/FR4 material.  We always start with the highest quality G10/FR4 material when producing fabricated parts.

Many of the most common uses for G10/FR4 material are in the electrical industry. A lot of the technical specifications and insulation parameters for high voltage dielectric materials require G10/FR4 parts to be a precise fit and of high quality. We always machine G10 dry while most industries use CNC fluids to keep the tooling cool during machining. We believe this destroys the electrical insulation values of the material on the surface and sometimes, in extremely high voltage applications, causes surface arcing on the CNC fabricated FR4 part. By machining the G10/FR4 dry, this concern becomes a non-issue thus providing a higher quality G10/FR4 part than most the CNC industry can provide.
