3M™ Circuit Plating Tape 851 with polyester film and blended silicone and rubber adhesive used for PCB masking and other high temperature applications. Thick adhesive coating. Green, 4.0 mil thick.
Reduce undercutting with the blended silicone and thick rubber adhesive of 3M™ Greenback Printed Circuit Board Tape 851. Our tape can be used for PCB masking and other high temperature applications. It has a polyethylene tape core instead of cardboard, and a polyester backing that reduces stretch and recovery of tape. It also helps achieve an even stop off line. Our tapes feature an adhesive that works better when no ovens are used to heat tape and boards, and a thick coating that helps block out solutions between fingers.
