LAMINATES FOR PCBs AND PCB INSULATORS

These specialized copper clad laminates or electrical grade laminates are manufactured by Current, Inc. here in the U.S. 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 to solely manufacture these highly specialized copper clad laminates and are one of the few electrical grade laminates manufacturers to still operate and maintain a manufacturing facility here 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 on to the FR4 substrate. It is commonly used for PCBs.

FR4 COLORS: BLACK*, BLUE & YELLOW, RED, ORANGE & TAN AS WELL AS NATURAL

Colored FR4 is available in black, blue and yellow, as well as 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 FR4 is manufactured in multi-tetra and di-functional epoxies.

We also manufacture high-temperature copper clad laminates in FR5 with the same functionality, but exhibiting better flexible strength at elevated temperature (177oC.)

CYROGENIC GRADE G10 NB

IPC GRADE / CRYOGENIC GRADE G10 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 G10-CR. G10-CR conforms to Mil Spec Mil-I-24768/2 Type GEE. G10-CR contains no halogens and can be used in nuclear and aerospace applications

CLASS A/B

Tolerance value is determined by normal base thickness (less cladding). Tolerance is applied over the based 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.

FAQs

What types of EGL products does Current make?

Our electrical grade laminate products include copper-clad G-10 sheets that are used for circuit boards. They can withstand high pressures and high temperatures. These sheets can be made with copper on either one, neither, or both sides for various uses. They can be manufactured in many different colors or multilayered as well.
