^{3M General Purpose Polyimide Film Tape 7413T  silicone adhesive 聚酸亞胺薄膜膠帶矽膠黏劑}

3M General Purpose Polyimide Film Tape 7413T / 7413TL is a tape consisting of a polyimide film and silicone adhesive designed for solder masking or other very high temperature applications.

Adhesion to Steel: 18 oz./in. width (20 N/100 mm)
Tensile Strength at Break: 29 lbs./in. width (508 N/100 mm)
Elongation at Break: 62%
Backing Thickness: 1.0 mil (0.025 mm)

Total Tape Thickness: 2.4 mils (0.061 mm)
Temperature Use Range: -100°F to 500°F (-73°C to 260°C)

At room temperature, the properties of polyimide and polyester films are similar. However, as the temperature increases, the properties of the polyimide film are less affected than polyester.   Polyimide film does not soften at elevated temperatures, thus the film provides an excellent release surface at elevated temperatures.

Mask for protection of gold fingers of printed circuit boards during wave solder, solder reflow or solder dip process.  Release surface in fabrication of parts cured at elevated temperatures.
