^{3M Copper Foil Shielding Tape 1181 Acrylic Adhesive 16072}

^{3M 金屬銅箔膠帶 1181 丙烯酸膠黏劑 16072-1}

3M 1181 Tape consists of a 1-ounce deadsoft copper foil backing and a unique electrically conductive pressure-sensitive acrylic adhesive.
• Deadsoft 1-ounce copper foil backing
• Conductive acrylic adhesive
• Supplied on a removable liner for easy handling and diecutting
3M EMI Shielding Tape 1181 is for EMI shielding, static charge draining, grounding; solderable; easily die cut.

3M 1181Tape 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 3M 1181 Tape, typical shielding effectiveness (far field) is in the range of 60dB to 80dB (30 MHz to 1 GHz). 3M 的銅箔 就算沒有鍍東西  也不會像一般銅箔 一樣容易氧化或是變色  表面有特殊處理
