Technical Data May 2011 3MTM Circuit Plating Tape 1280 Product Description 3MTM Circuit Plating Tape 1280 is a polyester film tape with unique adhesive for printed circuit board masking during electroplating. Product Construction Backing Adhesive Color Standard Roll Length Polyester Silicone/Rubber blend Red 72 yds. (65 m) 144 yds. (132 m) Typical Physical Properties Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes. ASTM Test Method Adhesion to Steel: 31 oz./in. width (33.9 N/100 mm) D-3330 Tensile Strength at Break: 30 lbs./in. width (525.4 N/100 mm) D-3759 Elongation at Break: 135% D-3759 Backing Thickness: 0.9 mils (0.020 mm) D-3652 Total Tape Thickness: 3.6 mils (0.091 mm) D-3652 Features * Low stretch polyester film for machine, as well as hand application. * Solvent clean up of the board is recommended to facilitate subsequent soldering. * Polyester backing reduces stretch and recovery of tape and associated uneven stop-off line. * Thick adhesive coating reduces undercutting because adhesive helps block out solutions between fingers. Application Ideas * Masking of many printed wiring boards during solder stripping and precious metal plating of fingers. * Splicing of silicone treated papers. Application Techniques * Must be firmly pressed down by equipment with rubber-covered rollers. Hand rolling usually does not provide enough pressure. A vivid outline of the circuit leads usually indicates that adequate pressure was used. * Tape generally performs better when no ovens are used to heat tape and boards. 3 3MTM Circuit Plating Tape 1280 Storage Store under normal conditions of 60 to 80F (15 to 27C) and 50% R.H. in the original carton.
