1.Heller has developed Pressure Cure Oven (PCO) or Autoclave to minimize voiding and increase adhesion strength for bonding processes typically used in die attach andunderfill applications. PCO pressurizes air into a rigid vessel and heats with forced convection. When the curing process is complete, the pressure oven automaticallyrelieves its pressure to 1atm and cools.
2. PCO pressurizes air into a rigid container and heats and cools it by forced convection ;
The heater, heat exchanger and blower are located inside the pressure vessel ;
After the curing process is completed, the pressure curing furnace will automatically reduce the pressure to 1atm and cool down .
