PB Series
Achieve excellent throughput, reliability, and low cost of ownership with the YES-PB Series tabletop vacuum cure. Patented YES technologies for vacuum curing ensure shorter cure time and increase throughput over atmospheric curing by more than 2-3x, with better outgassing, and better thermal and dielectric properties. The PB Series includes the PB8 (for up to 2 cassettes of 200mm wafers) and PB12 (for up to 2 cassettes of 300mm wafers), and is used extensively for polyimide, epoxy and wafer-to-wafer (WtW) bonding anneal. Using YES’s lab-to-fab capabilities, develop and test your innovative product ideas on the PB Series and when ready to scale, transition seamlessly up to the high-volume production VertaCure system.

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.

Innovative Technology

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.
