Vapour Phase Oven

Pfpe condensing on the pcbs.

Vapour phase oven.

The heating up phase the evacuation of the autoclave and cooling. The liquid used is chosen with a desired boiling point in mind to suit the solder alloy to be reflowed. Unlike ir or convection batch type ovens with varying temperature control concerns our vapor phase ovens provide you with evenly distributed temperature throughout the production cycle completely under your control. Generally there are three steps to the process.

Due to different magnitudes of heat transfer the vapor phase drying process allows for faster drying whereas the hot air process is easier to implement. Vapour phase oven the heating of the pcbs is sourced by thermal energy emitted by the phase transition of a heat transfer liquid e. As the vapor has a higher density it is heavier than the surrounding air. In a vapor phase oven limitations of the physical temperature reliably prevent overheating of any part in the soldering process.

Late last year when i was trying to buy a toaster oven to convert i started looking at what would be involved in making my own vapor phase oven. This allows the soldered parts to remain sealed inside a neutral atmosphere. A 230 c boiling fluid g. Most vapor phase ovens cost almost as much as a multi zone conveyor oven which can handle orders of magnitude more boards per hour but the ones from imdes are far cheaper.
