1281
***Discontinued*** PCB Electroplating Mask
Discontinued 3M1281 is a 2.6 mil polyester film tape with a special adhesive for printed circuitry masking during electroplating of solder mask over bare copper (SMOBC) printed boards. This low stretch polyester film can be applied by machine, as well as by hand. The tape must be firmly pressed down by equipment with rubber covered rollers or a rubber covered platen press. Hand rolling usually does not provide adequate pressure. A vivid outline of the circuit leads indicates adequate pressure was used. Solvent clean up of the board is recommended to facilitate subsequent soldering. When using solvents, be sure to follow the manufacturer's precautions and directions for use when handling such materials. 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 40 % to 50% relative humidity in the original carton.
