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