QTEK High Temperature Masking Tape
QTEK Masking Tape is a polyimide, pressure-sensitive, adhesive tape with silicone resin, which shows excellent dielectric insulation properties, high heat resistance and excellent solvent resistance. These properties result in a tape with remarkable dimensional stability and excellent electrical and physical properties over a wide range of temperatures. QTEK High Temperature Tape is ideal for masking gold fingers of printed circuit boards during wave solder or solder dip process.
QTEK High Temperature Dots
QTEK High Temperature Dots are used for solder wave masking and electrical insulation. They are composed of a polyimide film masking dots with silicone adhesive on a clear easy-release liner. QTEK High Temperature Dots are both flame and chemical resistant.
Applications of QTEK High Temperature Tape
- Masking for protection of gold fingers of printed circuit boards during wave solder or solder dip process.
- Protection for parts cured at elevated temperatures.
Advantages of QTEK High Temperature Tape
- Offers optimal performance in electrical and thermal insulation.
- Highly resistant to heat and chemicals.
- Puncture and tear resistant at high temperatures.
