ABSTRACT:
A system for the thermal and/or liquid treatment of edge supported substrates, such as printed electronic circuit boards and hybrid circuits. The system includes an elongated tunnel treating chamber. The system includes a conveyor system comprised of a pair of lubricant-free tape conveyors supported for movement through the treating chamber on a plurality of spaced apart parallel pins extending laterally inwardly from a pair of parallel elongated rail tracks. A lip on the rail track is closely spaced from and partially overlies the tape conveyor. The lubricant-free tape conveyor is comprised of a closed loop flexible steel tape provided with a plurality of longitudinally spaced apart vertical tabs throughout its length. The tabs are in longitudinal alignment, spaced inwardly from the edges of the tape and provide lateral support for substrates suspended between a pair of conveyor tapes.
