3M™Circuit Plating Tape 851 is a green polyester film tape with a unique conformable adhesive for printed circuit board masking during electroplating.
 
Application:
• 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.
