Polyimide consisting of a polyimide film and silicone adhesive designed for high temperature masking applications, including the protection of gold edge fingers and edge connectors during wave soldering and reflow soldering processes within the PCB assembly industry. It is used in electrical insulation application meeting class H requirements.
Main Features:
. Thin and conformable enabling masking of uneven sufaces.
. Wide operaturing tempreture range up to 500��F.
. Excellent electrical insulation
. Remove clearly without adhesive residue after exposure to heat/chemical
Applications:
. Masking for protection of gold fingers and edge connectors during wave soldering and reflow soldering processes or solder dip process within the PCB assembly industry.
. Release surface in fabrication of parts cured at elevated temperatures.
. Widely used for electrical insulation on transformer, motor, coil, PCB masking and so on.
PE film and Paper carton sizes.
This tape is with a courier of PET film , coating silicone adhesive on one side of it. The tape can be used to protect the surface during powder spraying and curing process in industry. Due to an excellent feature of silicone adhesive, it will leave no residue on surface after peeling away.

Very soft copper foil backing and a unique electrically conductive pressure-sensitive acrylic adhesive.
? Conductive acrylic adhesive
? Supplied on a removable liner for easy handling and diecutting.
Copper tape is typically used for applications requiring excellent electrical conductivity from the application substrate through the adhesive to the foil backing. Common uses include grounding and EMI shielding in equipment, components, shielded rooms, etc. The copper foil backing is solderable and resists oxidation and discoloration.
For Copper Tape, typical shielding effectiveness (far field) is in the range of 60dB to 80dB (30 MHz to 1 GHz).
