Key Applications
1. Flexible Circuit Protection
Brown circuit board high temperature tapeprevents copper trace oxidation during reflow soldering processes. TheSelf-adhesive back blocking spray paint tapevariant enables temporary masking with 0.05mm thickness precision.
2. Motor Insulation
EV manufacturers employPI material high temperature resistant 300 tapefor slot lining applications, achieving Class H insulation (180°C rating) with 50% space savings versus traditional mica solutions.
Case Study: Satellite Assembly
Lockheed Martin's 2023 Jupiter probe utilizedStrong adhesion and blocking high temperature tapein its power distribution unit. The tape maintained adhesion through:
· 15 thermal cycles (-190°C to +125°C)
· 98% vacuum exposure
· 500 MeV proton radiation
Selection Guide
When choosing betweenAdhesive PET material high temperature tapeand silicone-based alternatives, consider:
· Adhesion strength (>20 N/25mm required for SMT stencil masking)
· Outgassing levels (<1% TML meets NASA ASTM E595)
· Chemical resistance (withstands flux cleaners and IPA)
