Electrical Grade Laminates

LAMINATES FOR PCBs AND PCB INSULATORS

These specialized copper clad laminates, or Electrical Grade Laminates, are manufactured by Current, Inc. here in the United States. We offer competitive pricing, excellent quality, and reliable delivery. We specialize in custom thickness, coppers and colored applications for short runs, prototypes, and production runs.


Our Warren, OH facility manufactures these highly specialized copper clad laminates and are one of the few electrical grade laminate manufacturers to still operate and maintain a manufacturing facility in the U.S.

COPPER CLAD FR4

Our FR4 Copper Clad Laminates are a fire rated Electrical Grade, dielectric fiberglass material created under high pressure with electro deposited HTE (high-temperature elongated) Copper Laminated onto the FR4 substrate. It is commonly used for PCBs.

FR4 COLORS: BLACK, BLUE, YELLOW, RED, ORANGE & TAN AS WELL AS NATURAL (other colors available upon request)

Colored FR4 is available in black, blue, yellow, and natural. Our black Copper Clad Laminates and Electrical Grade Laminates are used for PCBs with light blocking capabilities for LEDs, night vision, and aerospace applications. Colored FR4 is available in a solid color throughout and a 50% natural and 50% color configuration.

Note: All of our FR4s are manufactured in multi-tetra and difunctional epoxies.
WE ALSO MANUFACTURE HIGH-TEMPERATURE COPPER CLAD LAMINATES IN FR5 WITH THE SAME FUNCTIONALITY BUT EXHIBITING BETTER FLEXIBLE STRENGTH AT ELEVATED TEMPERATURE (177 oC)

CRYOGENIC GRADE G-10 NB

IPC GRADE / CRYOGENIC GRADE G-10 is an electrical and mechanical grade of glass cloth laminate impregnated and cured with a non-brominated epoxy resin. It is also referred to as G-10-CR. G-10-CR conforms to Mil Spec Mil-I-24768/2 Type GEE. G-10-CR contains no halogens and can be used in nuclear and aerospace applications.

THICKNESS/COPPER COMBINATIONS:

In Natural:

RANGE: .0025″ – 2.000″ with any copper combinations from ½ oz – 10 oz., single- or double-sided, in Class A, B or C (see chart below).

In Colors:

RANGE: .0065″ – 2.000″ with any copper combinations from ½ oz – 10 oz., single- or double-sided, in Class A, B or C (see chart below).

GLASS TRANSITION TEMPERATURE, TG (C):

  • GF Di-functional:135
  • GH Multi-functional:150-177

AVAILABILITY:

In most cases, our lead time ranges from 1 – 2 weeks depending on custom thicknesses, colors and coppers. We also have same day to 24-hour turnaround on all JIT or blanket order stocking programs, with great credit terms for approved customers. Inquire about this program to see if you qualify.

CLASS A/B

Tolerance value is determined by normal base thickness (less cladding). Tolerance is applied over the base plus cladding, with no additional tolerance for cladding thicknesses allowed.

CLASS C

These tighter tolerance values are determined by normal base thickness (less cladding). Tolerance is applied to base thickness only, and through product selection, at 15% premium over CLASS A/B material.
