Abstract
A reflow apparatus for soldering has a tunnel and a pipe which form an endless passageway for hot gas. Infrared panel heaters are disposed inside the tunnel for heating printed circuit boards which travel through the tunnel on a conveyor. Hot gas is made to circulate through the passageway by a flow-producing device. A filter is disposed in the passageway for removing particles from fumes which are formed during soldering.
