[*Contact us if you need customize size*] 

These discs/dots are manufactured from commercial grade polyimide film with a special silicone adhesive. The polyimide carrier is only 1 Mil, making this tape extremely conformable for irregular shapes and surfaces. Designed for high temperature masking found in conformal coating of PCBs, protection of gold fingers during circuit board soldering and electrical insulation of high temperature coils, motors and transformers.
