Up For Auction 5 rolls of 3M Scotch 851 Circuit Plating Tape 1/2 inch X 72 yards Color : Translucent Green P/N : 851 9141 368 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. Application Techniques • Low-stretch polyester film can be applied by machine or by hand. • 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. • Solvent* clean-up of the board is recommended to facilitate subsequent soldering.  *Note: Be sure to follow the manufacturer’s precautions and directions for use when using solvents.
