The TORCH180 Wafer Bonder is primarily driven by mechanical pressure. For the pressure application unit, this design adopts a precision pneumatic control system and a self-developed positive pressure air bag mechanism to achieve high-precision pressure exertion. A vacuum-sealed structure is employed for the overall chamber and structural design. The bonding process can be conducted in a vacuum environment or a protective atmosphere filled with two or more inert gases, which enhances the product bonding quality. The complete equipment consists of the following systems: pressure application system, vacuum system, heating system, temperature control system, cooling system and so on.
