Description:
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.
Advantage:
- Polyester backing reduces stretch and recovery of tape associated with uneven stop-off line
- Thick adhesive coating reduces undercutting because adhesive blocks out solutions between fingers
- Specially designed adhesive that generally performs better when no ovens are used to heat tape and boards
- Polyethylene tape core instead of cardboard
Recommendation:
- Use for masking of many printed wiring boards during solder stripping and precious metal plating of fingers
- Splicing of silicone coated papers
