Polyimide Curing Oven
A clean process oven designed for
polyimide baking and curing applications
e Despatch PCO2-14™ electrically heated oven was designed to meet
the speci c process requirements for hard baking polyimide coatings in
an inert atmosphere. is high-performance, clean process oven (ISO
Class 5/Class 100 recirculated air ow) o ers many unique components,
including a pressure relief system, an oxygen control system and a process
monitoring system which allows the oven to achieve the strict oxygen level
and atmospheric requirements involved in polyimide curing.
Pressure Relief System: In the “hard bake” polyimide cure process, residual
solvent is removed and desired surface properties are nalized. e
process of removing solvents requires that the oven contain equipment
to help prevent and collect solvent condensation. Despatch designed the
PCO2-14™ with a pressure relief system that includes a removable “cold
trap”, an easy-to-clean condensate trap that helps to prevent polyimide
buildup in the oven’s exhaust.
Process Monitoring System: e oven’s
PC features Protocol 3™ so ware to
allow for communication between
the PC and the oven, an Ethernet
connection and a 15” (38.1cm) at
panel display screen. e Protocol 3™
so ware communicates directly with
the oven’s Protocol 3™ controller, O2
controller, O2 monitor and integrated
PC to observe and data log entire
cycles and provide the user with realtime information on set points, actual
chamber temperatures and O2 levels
throughout the entire process.
Oxygen Monitor and Control System: e
PCO2-14™ is an inert atmosphere oven which
allows the oxygen level to be maintained at
20ppm or less to help prevent oxidation of the
polyimides being cured. e oven contains an
O2 monitor which is wired to the purge valve
and turns the nitrogen purge on whenever the
oxygen level is above the O2 monitor set point.
Once the nitrogen purge is complete, the O2
level is maintained at a set point by a controller
that operates a modulating valve during the
curing process. is process minimizes the
nitrogen usage and allows for consistent and
repeatable product curing.

Notes: Uniformity figures are based on a nine-point test conducted in an empty oven after stabilization period. Uniformity can vary slightly depending on
unit and operating conditions. Minimum operating temperature and cooling times are based on 20°C ambient temperature measured at the fresh air inlet.
Times to temperature with no load are based on non-ISO Class 5 (non-Class 100) conditions. Class 100 HEPA filtration will limit ramp rates to 5°C per
minute. Specifications are subject to change without notice. If the existing specifications differ from yours, ask about our customizing capabilities.
Warning: Despatch PCO2-14TM ovens are not to be used with flammable solvents, materials or enclosed containers.
Soft bake of the polyimide coatings must be done in a Class A oven prior to hard baking in the PCO2-14
