3M™Circuit Plating Tape 851 is a green polyester film tape with a unique conformable adhesive for printed circuit board masking during electroplating.
FEATURES
- 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.
APPLICATIONS
- For masking printed circuit boards during solder stripping and precious metal plating of fingers.
- Splicing of silicone coated papers.
