Heating / drying oven Aurel Automation

AUREL A206 Dryer/Curing Oven system

Description
The AUREL A206 dryer system is special designed for predrying of pastes in thick film technology.

Applications
• IR Drying of Thick Film pastes
• IR Curing of adhesives and polimeric pastes

Prior to being submitted to be firing process, substrates with screened-on inks/pastes must be predryed to evaporate the solvents.
Infrared heat is the only heating method available by which thick film pastes can be properly dryed with optimum results.
This is because infrared heat waves penetrate the material and dry the inside of the material first, then dry outwardly to the surface.
Convenction heat causes the outside of the paste to dry first forming a film through which it is difficult for the solvent within to pass.
The solvents actually become partially trapped and as they eventally are released cause cracks in the surface of the material.
Consequently the surface is irregular, resulting in reduced conductivity or inconsistent resistivity.
The new model A206 predrying oven was designed to prevent the problems outlined.
It's design criteria are based on extensive experience in thick film technology, to provide the user with a machine that assures optimum results.
