Abstract:
1. A reflow apparatus for solder joining electronic components to a substrate, the apparatus comprising: a reflow chamber; a conveyor to convey a substrate within the chamber; at least one heating element to provide heat to reflow solder on the substrate; and at least one system to remove contaminants generated from the reflow solder, the at least one system being coupled with the chamber for passage of a vapor stream from the reflow chamber through the system, the at least one system comprising a contaminant collection unit in fluid communication with the vapor stream, the contaminant collection unit including wherein the coil is configured to receive cooled gas therein, the arrangement being such that when introducing cooled gas in the coil, contaminants in the vapor stream condense on the coil, and when ceasing the introduction of cooled gas in the coil, and activating the heating element to deliver warmed gas through the outlet to the coil, contaminants in the vapor stream are released from the coil and collected in the collection container.
