PCO 520
A Pressure Curing Oven (PCO)—also known as an autoclave—minimizes voiding and improves adhesion strength during bonding processes such as die attach and underfill.
✔ The system pressurizes air in a rigid chamber and utilizes forced convection for heating and cooling.
Key thermal components—heaters, heat exchangers, and blowers—are fully integrated inside the pressure vessel.
✔ Upon completion, the unit automatically releases pressure to 1 atm and cools.
Building on our innovations in SMT solder reflow, including full-convection technology and efficient nitrogen usage, we now offer a complete family of custom pressure curing and reflow ovens designed for a wide range of pressure-based applications.
Heller provides multiple pressure curing oven models with various chamber sizes suitable for R&D environments and high-volume production, with optional cleanroom and automation configurations.
✔ These systems maintain constant chamber pressure while heated air (or nitrogen) circulates through a convection heater module.
✔ The high-reliability fan motor moves heated air continuously across the pressure chamber to deliver uniform thermal processing.
✔ An optional vacuum pump can be added to improve void removal.
✔ Vacuum is applied at the beginning of the curing cycle to eliminate larger voids, while smaller voids are removed later under pressure.
✔ Using both vacuum and pressure can help achieve shorter cycle times.
✔ Typical process time: 120 min or per user spec
✔ Operating temperature: 60°C – 200°C
