Abstract
The lead finish can be greatly improved on leaded electronic components in a vapor phase reflow process without extra process steps by providing an improved conveyor belt having supports for carrying the components in bug down orientation while preventing the leads from substantially protruding through the plane of the conveyor mechanism and simultaneously allowing for the free flow of the heated vapor through the conveyor belt and on top of the belts such that the leads of the electronic components rest on the tape. The remaining portion of the belt is of a large grid mesh to permit the free flow of vapors in the upper portion of the reflow chamber.
