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 capable of not only conventional vacuum processing but also pressurized processing up to 0.4 MPa. This allows for a wide degree of variation in chamber pressure. Consequently, voids in the solder joints can be minimized, achieving virtually void-free soldering. VPF is also capable of fluxless soldering through the reduction of oxide films using formic acid vapor. The system can be equipped with a temperature-controlled formic acid bubbler, supplying nitrogen gas mixed with formic acid at a constant concentration into the process chamber. Forming gas is also available for the same purpose. With these outstanding capabilities, the VPF offers users exceptional flexibility in fluxless and void-free soldering applications. |
