Table-top vacuum reflow oven TVF200

 Back to Product List

Capable of heating up to 450℃, process to remove oxide film with formic acid available, fast board cooling function as standard, space-saving tabletop type, cost effective vacuum reflow oven TVF200.

TVF200 vacuum soldering process significantly reduces voids inside the solder by changing the pressure inside the process chamber, enabling high-quality void-free soldering.
Usable heating area of 200mm x 200mm with 50mm space in height, supports heating from top and bottom of workpiece. The pressure can be set freely from atmospheric pressure to 10Pa, and the pressure and heating profile can be flexibly and simply programmable on a touch panel.
By using a formic acid bubbler unit (optional) with its temperature control function, a mixed gas of formic acid and nitrogen gas is generated at a stable concentration. The process with its mixture gas removes oxide film on the workpiece, enable a flux-less soldering.

  In atmospheric reflow, there is no pressure change in the atmosphere, so the solder solidifies while voids remain trapped.
  By varying the pressure inside the process chamber from atmospheric pressure to a vacuum of around 10 Pa, voids in the solder can be significantly reduced.
