The Science Behind Conveyor Oven Thermal Profiling

between 1.0C and 3.0C/second. In vapor phase ovens, a preheat zone brings the PCB up to 70-80C at 1.0 to 3.0C/sec., but once the PCB reaches the vapor, the ramp rate often exceeds 5.0C/sec. It is unclear why, but the maximum negative slope (ramp-down rate) is often ignored. It would seem that the

Transformer Vapor Phase Process Prolec-GE Waukesha Inc.

FINAL DRY OUT — VAPOR PHASE PROCESSING. Final dry out begins by loading the entire core and coil assembly into one of Prolec GE Waukesha vapor phase vacuum chambers. The cycle begins by evacuating the chamber to a low pressure, removing the majority of oxygen from the atmosphere. At this point, solvent vapor is introduced which begins to condense on the …

Asscon Vapor Phase Soldering -

In the last process step the soldered and dry PCB is cooled in a cooling zone. Many test proved that on one and the same PCB the amount of voids after vapor phase soldering is smaller compared to convection reflow soldering. To reduce further the amount of voids Asscon developed a vacuum section which can be added to the high end vapor phase ovens.

Vapor Phase Drying Plant Manufacturer from Pune

In vapor phase drying system, solvent vapors are sent into the vessel. The solvent vapors are at high temperature (Up to 125 Deg C) and the job is under atmospheric temperature. The vapor meets the job directly the job gets heated. In the process vapors are cooled get condensed. The latent heat is released which is utilized for job heating.
