Pressure Cure Oven (PCO)
CONFIDENTIAL
Introduction
Pressure Cure Oven (PCO) or Autoclave is used to minimize voiding and increase adhesion strength for bonding processes typically used in die attach and underfill applications
PCO pressurizes air into a rigid vessel and heats & cools with forced convection¬Heaters, heat exchangers and blowers are internal to
the pressure vessel When the curing process is complete, the pressure oven
automatically relieves its pressure to 1atm and cools
