COPPER Foil
Insulectro stocks, distributes and supports Copper Foil for Rigid, Rigid-Flex and Flex designs.
About COPPER FOIL
Insulectro offers Copper Foils from many world-class producers that are designed to help our customers achieve their high-performance design parameters.
These foils cover Electrodeposited (ED) and Wrought (RA) needs with all materials released to the Printed Circuit Boards industry standard of IPC-4562.
Foil options from 1.5µm up to 105µm as standard, heavier coppers on request all to support superior adhesion, signal integrity for HSD, HDI, RF and MSAP requirements.
Our technical expertise can help connect the right material for your Rigid, Rigid-Flex or Flex design.

Rigid and Rigid-Flex Circuits
Highly reliable, matte side treated grade 3 HTE electrodeposited foil for outer layer applications with excellent adhesion propeties on a wide range of resin systems.
Low-profile, high tensile strength electrodeposited copper foil, suitable for fine etching in the subtractive process. Used to support semiconductor packages, HDI, and Flexible PCB. With treatment on the matte side of the foil.
Very low-profile electrodeposited copper foil for inner layer application with treatment on the matte side of the foil. Arsenic & cyanide-free with low zinc treatment properties.
Reverse treat electrodeposited copper foil for inner layer application with a very low profile for HDI and RF demands with treatment on the drum or shiny side of the foil.
Reverse Treatment
JX Metals Corporation JXEFL
Reverse treat electrodeposited copper foil for inner layer application with a very low profile for HDI and RF demands with treatment on the drum or shiny side of the foil.
Flexible Circuits
Very low-profile, rolled-wrought, low-temperature annealable foil with excellent dynamic and static flex properties due to enlarged grain structure and orientation. Suitable for Flexible and Rigid-Flex PCB applications.
Very low profile, annealed-wrought foil suitable for flexible PCB applications. Available in single or double treated finishes.
MSAP (Tighter Line Spaces)
MicroThin is an ultra-thin foil on an 18µm carrier foil to support very fine pitch patterns. Target L/S = 35/35 or less.
