With the continuous upgrading of smartphones, users are becoming more demanding on the stylish and textured requirements of mobile phones. The all-metal body has almost become a standard, even the low-end mobile phone has begun to transition from a plastic back shell to an all-metal body. The wide application of metal materials also gives HAF thermal reaction tapes a chance to make a big impact. For increasingly thin and light mobile phones, HAF thermal reactive tape requires only a small bonding area to achieve superior bonding.

Tesa's new tesa HAF 58492 is a black thermal reaction tape based on PET. The thickness of 72μm further expands the selectivity of this series. This series of products has strong adhesion, and the special PET substrate design prevents the mesh from breaking through the ink during pressing, avoiding poor appearance.
Features:
· Reliable viscosity and aging resistance
· High adhesion for narrow surfaces and ultra-thin design voids
· Very low gel overflow rate
· Excellent dimensional stability, easy die cutting
· PET substrate prevents the mesh from breaking through the ink when pressed
· Suitable for long-term high stress applications
· The gel can still be elastic after bonding
· Halogen-free, in line with current ROHS standards
Tesa HAF 58492 can bond metal parts to plastic or metal surfaces such as stainless steel, aluminum and PMMA, ABS or PC:
· Structural bonding of parts in electronic equipment
· Speaker network fixed
· Button fixing
· Camera window and housing are fixed
· Fixing of decorative metal parts
At room temperature, tesa HAF is not sticky, and the method of use is mainly carried out by heating and pressurization, and is divided into two steps of pre-pressing and final pressing.
1. Pre-pressing: pre-press the hot melt adhesive to the surface of the sheet with a lower temperature to position and tear off the release paper;
2. Final press: final press at a higher temperature to achieve the desired bond strength.
Product Series
Welding diodes are available for medium frequency (over 2KHz) and high frequency (over 10khz) applications.They have very low on - state voltage and thermal resistance. Welding diodes are designed for medium and high frequency welding equipment and optimized for high current rectifiers. The on-state voltage is very low and the output current is high.
