CNC G10 Material Machining And Fabrication

What Is G10 Material?

FR-4 glass epoxy composite laminate G10 material, commonly referred to as Micarta*, garolite or Bakelite*, is a thermoset fiberglass composite manufactured from glass filament cloth with a di-functional or tri-functional epoxy binder. It is often used in applications that require dimensional stability, electrical insulating properties, and moisture resistance.  It is used across a wide range of electrical and mechanical applications.

What Is the difference between G10 and G10 FR-4 Material?

G10 materials fall under the category of thermoset industrial laminates produced from a layered construction of substrates impregnated with a thermoset resin and cured under heat or pressure.  They fall under standards published by NEMA (National Electrical Manufacturers Association) which provide minimum values for grades of thermoset laminates.

NEMA provides two grade values for this category of industrial laminates, G10 and FR4.  The FR4 is the fire retardant grade of G10.

G10 Material Properties | G10 Material Specifications:

The appearance or natural color of G10 / FR4 glass reinforced epoxy is light green to yellowish laminate. The laminate is typically manufactured from continuous woven glass fabric and impregnated with an epoxy resin that provides properties ideal for electronics applications due to superior electrical insulation properties.

G-10 FR-4 glass epoxy laminate meets the following specifications:

  • G10 FR4 : Mil-I-24768/27 GEE-F
  • G10 : Mil-I-24768/2 GEE
  • G10 FR4 : LP 509
  • G10 FR4 : MIL P 18177 Type GEE
  • NEMA FR4

G-10 FR4 Sheets provide:

  • A maximum continuous operating temperature: 285°F
  • Excellent machinability
  • Excellent electrical characteristics
  • Low moisture absorption
  • Great dimensional stability (shrinkage is less than 1%)
  • Abrasive Texture
  • Good chemical resistance particularly under moist and humid conditions
  • Extremely high mechanical strength
  • Superior adhesive properties
  • Good dielectric loss properties
  • NEMA FR4 fire resistance
  • Commonly known as Micarta*, Garolite or Bakelite*

CNC Machining G10 Material

G10 FR4 sheet can be CNC machined up to +-.005 tolerance.  Jaco offers G10 drilling, milling, and machining services to either cut to size to or machined to your CAD drawings.  From 5-axis machining centers to routers, we can quickly and easily cut your G10 FR4 to your exact specifications. Get custom G10 machining services from the premier Ohio plastics fabricator, Jaco Products.

Unlike machining metal, machining G10 can present challenges due to the highly abrasive glass fillers.  Metal machining speeds are typically too high for composites resulting in delamination.  Since Jaco, specializes in plastic machining and does not machine any metal components, equipment from machine tools to dust collection, is unique to the specific requirements of machining composites, laminates and glass filled resins.

G10 FR4 Die Cut Parts

Jaco offers die cutting services of G10 FR4 material.  G10 FR4 is one of the most versatile laminates used as an electrical insulation material in electronics, PCBs, and mechanical lines.
