Thermal Release Tape

Thermal Release tape or thermal debonding tape is a special functional tape which functions as a regular tape sticking to a substrate or bonding two surfaces together under certain temperature, T(stable); however it debonds at another temperature, typically higher temperature (e.g. 15C higher T(debond)), as shown in Figure 1.Therefore it is quite useful for those applications where bonding and debonding are both required in the process.

Figure 1 Typical working conditions for thermal release tape

At a temperature less then T(stable), it bonds normally; after debonding, the tape itself starts rolling up from substrate; workers can easily peel it off.

Thermal debonding tape can be divided in two types: single-sided and double-sided tapes. From there, carrierless tape or transfer tape, half-deboning-half-regular can be further developed.

The uniqueness of this tape is the special additive. Its size remains constant until T(stable); then it starts to expands to several times of its original size, leading to the separation of bonding substrates, and debonding occurs.

We have quite large selections of thermal release tapes with releasing temperature ranging from 125 to 200 degree C while they are stable  below T(stable) which is about 15-20C below debonding temperature, T(debonding).
