R&D High-Temperature Vacuum Cure Systems
YES pioneered the use of vacuum curing, and has continued to perfect and patent the many innovations required to provide YES customers with superior film performance at twice the speed and half the cost of ownership of conventional cure technology.
The PB Series is the result of YES’s decades of experience. These dependable systems provide complete removal of residual solvents, uniform temperature distribution, complete imidization, and precise management of heating and cooling rates. YES’s industry-leading expertise can be seen in the superior performance of the PB Series: no post-cure outgassing; better thermal, mechanical and electrical properties; and better particle performance for advanced packaging and degas applications.
Easily set up programmable recipes on a touchscreen (and with optional remote process management software) for temperature uniformity, pressurization, and rapid air-based cooling. The PB12 accommodates two cassettes of 200mm/300mm wafers, and the PB8 accommodates two cassettes of 200mm wafers.
Precise process control, with excellent temperature uniformity and laminar gas flow
The YES-PB Series features innovative technology to improve vacuum curing speed, reliability, and efficiency while extending equipment life.
Chamber Exhaust Condensate Trap
Protect vacuum lines, valves, and vacuum pump performance from the accumulation of solvent condensates during the cure process. Easily dispose of the condensates.
Vertical Laminar Flow Technology
The PB Series directs gases from top to bottom to eliminate gas turbulence, resulting in excellent temperature uniformity and particle performance.
Air Cooling Technology
Achieve optimal temperature uniformity and rapid cooling times with air. Adjust air mixing ratio for chamber cooling and precisely control ramp down rates.
