1690 is a 1.5 mil (38 micron) special electrolytic grade, zero temper, high tensile copper foil clad on both surfaces with tin and coated with an aggressive acrylic adhesive system. This copper foil readily accepts solder and is corrosion resistant. 1690 is used in industrial and electrical applications and low level EMI/RFI shielding.
