AT544 35 Micron Tin Clad Copper Foil Masking Tape

• A very specific strip masking tape based on a 35 micron tin clad copper foil
• Electrically conductive acrylic adhesive
• Removable polyester masking tape
• Tin has much better resistance to oxidation than copper
• Easily soldered

Applications

A very specific strip masking tape based on a 35 micron tin clad copper foil coated with an electrically conductive acrylic adhesive and a removable polyester masking tape. Applied onto the inner door sections of electronic cabinets prior to powder coating or spray painting. The masking tape is then removed to expose a clean and electrically contactable tin layer. This tin layer can then form a complete EMI shield through contact with a suitable foam rubber door seal.
