G10 Fiberglass FR4 Glass Epoxy Machining

Also known as G10 fiberglass, FR4 glass epoxy, or FR4 glass fabric, G10/FR4 electrical grade epoxy resin exhibits extremely high strength, dimensional stability, and creep resistance, even at high temperatures. This composite material is commonly used for PCBs (printed circuit boards), insulators in electromechanical devices, and other similar applications. G10 fiberglass is notoriously difficult to machine, but Upland Fab has the skills, experience, and technology to produce high precision parts and components from this unique material.

 

G10/FR4 Electrical Grade Epoxy Resin

 

A type of phenolic laminate, FR4 glass epoxy is produced by applying heat and pressure to multiple layers of disparate specialty materials which have been impregnated with synthetic thermosetting resins. The heat and pressure polymerizes the individual layers into a single, laminated material.

 

Like other phenolic laminates, G10/FR4 electrical grade epoxy resin is extremely strong and stiff. FR4 glass fabric also exhibits a low coefficient of thermal expansion and outstanding electrical properties, making it an ideal material for electronic and electromechanical components. It is flame retardant and, with very low moisture absorption, is well-suited to use in high-humidity environments, and one of our most trusted laminate products we work with.

 

We also work extensively with G11 epoxy resin.

 

Precision Machining of G10 Fiberglass Parts

 

As noted, G10 fiberglass is very difficult to machine with precision. Upland Fab uses advanced multi-axis machining systems with special tools that enable us to deliver G10 fiberglass parts with exceptional precision, tight tolerances, and perfect repeatability. Our CNC machining technology allows us to manufacture parts with minimal handling and fixturing requirements; in many cases, even highly complex parts can be completed in a single operation.

 

We use DPD/MBD processes (Digital Product Definition/Model-Based Definition) that enable us to work directly from your CAD models. By working straight from your digital design files, we can eliminate machining errors and improve accuracy. The end result? More precise and cost-effective parts.

 

Top-Flight Communication Helps Keep You Up to Speed

 

At Upland Fab, we make communication a top priority. We provide consistent, reliable communication, with a single point of contact throughout your whole project, to keep you up to date as your project progresses. We stay in touch every step of the way.
