Vacuum & Pressure Reflow Oven VPF300 |
The VPF vacuum and pressure reflow oven has a wide heating area coupled with a unique rapid cooling function that expedites the cooling process leading to enhanced productivity. The VPF is not only capable of the conventional vacuum process but also pressurized process up to 0.4Mpa. This allows for a wide degree of variation of the pressure inside the chamber. Thus, voids in the solder joint can be minimized, resulting in nearly void free soldering. VPF is also capable of flux-less soldering by the reduction of oxide film by formic acid vapor. The system can be equipped with a formic acid babbler with a liquid temperature control which can supply Nitrogen gas mixed with formic acid at a constant concentration into the process chamber. Forming gas is also available for the same purpose. With the outstanding functions available on the VPF, users are offered a lot of flexibility in terms of fluxless and void-free soldering. |
