3M™Circuit Plating Tape 851 is a green polyester film tape with a thick adhesive of blended silicone and rubber. This tape is specifically designed for printed circuit board masking during electroplating, solder stripping and precious metal plating of fingers.
Product Features
Temperature - up to 170°F /76°C
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
Tape must be firmly pressed down by equipment with rubber-covered rollers or a rubber-covered platen press. Hand rolling usually does not provide enough pressure. A vivid outline of the circuit leads usually indicates adequate pressure was used
Construction
3.6 Mil Total Thickness
Roll Length - 72 yards
Specifications
Tensile Strength (lb/in) - 27
Elongation (%) - 124
Steel Adhesion (oz/in) - 29
