3M™ 851 Circuit Plating Tape 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
