Target Bonding Adhesive is a specialized adhesive used to securely bond sputtering targets to the backing plate. It plays a key role in processes such as physical vapor deposition (PVD).

Core Advantages

● Process Friendly

It typically cures at temperatures from medium to low, avoiding potential damage to target material properties from high temperatures, and is relatively easy to operate.

● Stress Buffering

With certain flexibility, it effectively alleviates stress generated between the target and the backing plate due to differences in thermal expansion coefficients.

● Overall Performance Stability

It has good chemical and mechanical stability, strong adhesion to various substrates (such as aluminum, copper, stainless steel, glass), and is environmentally friendly and non-toxic.

Application Fields

●  Ceramic and Brittle Target Bonding

Especially suitable for bonding ceramic targets such as ITO (Indium Tin Oxide) and SiO₂, which are brittle and require bonding for support and heat dissipation.

●  Thermally Sensitive or Special Targets

Suitable for targets that cannot withstand high-temperature bonding (such as certain oxide targets), organic targets, or temporary bonding applications.
