Transparent PET Silicone Tape – 155℃ High Temp Masking for Soldering

Produt overview

The Transparent PET Silicone Tape is a high-performance masking solution engineered to withstand the rigorous thermal demands of modern electronics manufacturing and industrial finishing. Featuring a clear PET film backing combined with a residue-free silicone adhesive system, this tape maintains its structural integrity and adhesion at continuous operating temperatures of 155℃. It is the preferred choice for PCB assembly technicians, powder coating specialists, and automotive paint shops. The crystal-clear backing allows for precise alignment over gold fingers, connector pins, and designated keep-out zones prior to wave soldering or oven curing. With a Breakdown voltage exceeding 5kV, it delivers the dual benefit of mechanical masking and electrical insulation. This tape removes cleanly in one piece after exposure to heat, leaving zero adhesive transfer and ensuring high first-pass yields in high-volume production environments.

Key Features

High Temperature Resistance: Performs reliably at 155℃ continuous operating temperature, making it ideal for wave soldering, powder coating ovens, and paint baking cycles without shrinkage or adhesive failure.

Excellent Electrical Insulation: Dielectric breakdown voltage exceeds 5kV, providing dependable protection for sensitive PCB components during soldering and high-potential testing.

Chemical & Solvent Resistance: Withstands exposure to flux, cleaning agents, and mild chemical baths commonly encountered in electroplating and PCB assembly processes.

Crystal Clear Transparency: Transparent PET backing enables precise visual alignment over gold fingers, connector pins, and registration marks, reducing masking errors and improving workflow efficiency.

Technical Data Sheet

Primary Applications

Wave Soldering & Solder Dip Masking: Protects PCB gold fingers, edge connectors, and test points from solder bridging and flux contamination during high-temperature wave contact.

Conformal Coating Masking: Creates sharp, defined boundaries for acrylic, silicone, and urethane coatings applied after SMT assembly.

Powder Coating Curing Ovens: Masks grounding studs, threaded holes, and bearing surfaces that must remain conductive and coating-free during the 150℃–155℃ bake cycle.

Automotive Paint Baking: Ideal for two-tone paint lines and protecting trim during high-heat refinishing cycles in body shops.

FAQ

Q: Is this tape specifically designed for wave soldering processes?

A: Yes. The 155℃ long-term rating and >5kV breakdown voltage make it an industry-standard choice for masking gold fingers and connectors during lead-free wave soldering.

Q: Does the tape shrink or curl when exposed to oven heat?

A: No. The stabilized PET backing resists shrinkage and edge lifting up to the rated 155℃, ensuring the masked area remains fully protected throughout the thermal cycle.

Q: Can this tape be used as an electrical insulator?

A: Yes. With a breakdown voltage exceeding 5kV, it provides reliable electrical isolation for components and circuitry during soldering and testing operations.

Q: Is the transparency necessary for industrial use?

A: Absolutely. The transparent PET film allows operators to visually align the tape precisely over small SMT pads, gold fingers, and registration marks, significantly reducing application errors.

Q: What is the recommended storage condition?

A: Store in a cool, dry place 23℃ and 65% relative humidity. Avoid direct sunlight and excessive heat to maintain adhesive properties for up to 6 months.
