Table-top Vacuum Reflow Oven TVF200 |
|
|
The TVF200 vacuum soldering process significantly reduces voids inside solder joints by modulating the chamber pressure, achieving high-quality, void-free soldering. Featuring an effective heating area of 200 mm × 200 mm with 50 mm clearance in height, it supports heating from both the top and bottom of the workpiece. The chamber pressure can be flexibly controlled from atmospheric pressure down to 10 Pa, and both pressure and temperature profiles can be easily programmed via the intuitive touch panel. By utilizing the optional formic acid bubbler unit with temperature control, a formic acid and nitrogen gas mixture is supplied at a stable concentration. This reduction process removes surface oxide films, enabling flux-free soldering.

|
| • | In atmospheric reflow, voids remain trapped inside the solder as it solidifies without pressure variation. |
| • | By reducing the pressure in the process chamber from atmospheric pressure down to approximately 10 Pa, voids in the solder joint are drastically reduced. |
