A 3.6 mil. green polyester film tape with a unique conformable adhesive for printed circuit board masking during electroplating. This 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. Be sure to follow the manufacturer's precautions and directions for use when using solvents. To obtain best performance, use this product within 12 months from date of manufacture and store under normal conditions of 60°F to 80°F and 50% relative humidity in the original carton.
