1285
***Discontinued*** PCB Masking Tape
Discontinued 3M1285 is a transparent blue polyester film tape with a rubber adhesive which resists plating and etching bath chemicals. Roller pressure must be monitored to ensure clean, residue-free boards after tape removal. Air pressure controlled equipment can be set at 30 - 40 PSI. Non-air pressure controlled rollers should be set no closer than 1/2 the PC board thickness. Heat should not be used during tape lamination. The low stretch polyester film of 1285 tape is designed for machine and hand application. 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.

Product Features
- Transparent blue polyester backing reduces stretch and recovery of tape and associated uneven stop-off line
- Thick rubber adhesive coating reduces undercutting because adhesive blocks out solutions between fingers
- Specially designed adhesive eliminates silicone residue
- Reduces or eliminates the need for solvents
- Higher adhesion requires less pressure to adhere to PC board surface
- Eliminates white stain after leveling or fusing
- Assures good anchorage of solder masks
- Assures good anchorage of conformal coatings
- Increases optimum solderability
- Saves money by reducing number of reject boards
- Saves time and money by eliminating silicone related board failures
- Reduces or eliminates solvent costs
- Saves on wear and replacement costs of rubber laminating rollers

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.
It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.
Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.
Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
