High-frequency electronic transformer tape technology

——The “invisible guardian” of the revolution from insulation to temperature resistance.

I. The core mission of adhesive tape: more than just bonding

In high-frequency electronic transformers, adhesive tapes are the structural engineers of precision electromagnetic systems and perform four key tasks:

? Insulation isolation: withstand voltage between windings ≥ 5.5kV (Mylar tape reference)

? Mechanical anchoring: vibration displacement ≤ 0.1mm after core wrapping (industrial grade standard)

? Safety Enhancement: Adoption of IEC 62368 Pitch Requirements (Core Value of Retaining Wall Tape)

? Air gap regulation: 0.05-0.2mm precision adjustment (affect leakage sense and efficiency)

II. The material showdown: three tape performance parameters PK

III. High-frequency scene selection strategy

1. Consumer electronics (GaN fast charging)

• Combined solution: Mylar tape (winding isolation) + Retaining wall tape (safety enhancement)
• Pain point breakthrough: thickness <0.1mm, resistant to 260°C reflow soldering

2. New energy vehicles (800V platform)

• Preferred for high temperatures: polyimide tape (180°C ambient temperature resistance)
• Vibration-resistant design: 3M VHB? tape additional core mounting

3. Industrial power supply (5G base station)

• Weatherproof program: polyimide + copper foil composite tape (EMI suppression ≥ 40dB)
