Vapour Phase Oven

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.

Vapour phase oven.

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. 3l becher pyrex heater cheap chinese like and an optional thermocouple reader. The liquid used is chosen with a desired boiling point in mind to suit the solder alloy to be reflowed. As the vapor has a higher density it is heavier than the surrounding air.

A 230 c boiling fluid g. 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. Pfpe condensing on the pcbs. Vapour phase oven the heating of the pcbs is sourced by thermal energy emitted by the phase transition of a heat transfer liquid e.

Generally there are three steps to the process. The vapor phase process is the ideal solution to reflow temperature control issues in small batch production runs. The heating up phase the evacuation of the autoclave and cooling. The two methods only differ in the heating up phase hot air and vapor phase.

This allows the soldered parts to remain sealed inside a neutral atmosphere.
