Main Applications
- Electronic component insulation
Used to protect components and improve insulation organization during electronic assembly. - Terminal and connector protection
Helps separate local conductive areas and maintain electrical isolation inside electronic structures. - PCB support insulation
Can be used to protect local PCB-related areas where controlled insulation is required. - General electronic module insulation
Suitable for electrical separation and fixing in electronic production and assembly work.
How to Choose the Right Tape Size
- Narrow widths are suitable for terminals, connectors, and compact component protection points.
- Medium widths are commonly used for standard electronic insulation coverage and internal assembly work.
- Wider rolls are better for larger modules or broader insulation areas.
- Thinner grades are easier to apply where compact fitting and flexibility are important.
- Thicker grades are more suitable when stronger insulation build-up or added surface protection is needed.
