A conveyor system is configured to transport the electronic substrates through the cleaning modules of a cleaning apparatus. The conveyor system includes a first outer frame member, a second outer frame member spaced from the first outer frame member, a bottom belt disposed between the first outer frame member and the second outer frame member, and a top belt spaced from the bottom belt. The bottom belt and the top belt are configured to receive a product carrier therebetween to transport electronic substrates along the conveyor system and through the cleaning modules. The conveyor system further includes a plurality of roller assemblies, with at least one roller assembly being coupled to the first outer frame member and at least one roller assembly being coupled to the second outer frame member. Each roller assembly is configured to apply a force on the top belt or the bottom belt.

A conveyor system is configured to transport the electronic substrates through cleaning modules of a cleaning apparatus. The conveyor system includes a first outer frame member, a second outer frame member, a bottom belt assembly disposed between the first outer frame member and the second outer frame member, and a top belt assembly spaced from the bottom belt assembly. The bottom belt assembly and the top belt assembly are configured to an electronic substrate therebetween to transport the electronic substrate along the conveyor system and through the at least one cleaning module. The bottom belt assembly or the top belt assembly includes a mesh material belt fabricated from heat resistant synthetic fibers. The conveyor system further includes a plurality of pins secured to the bottom belt assembly or the top belt assembly to create at least one lane along a length of the conveyor system.

Laned belt for cleaner

A reflow apparatus for solder joining electronic components to a substrate includes 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 system is coupled with the chamber for passage of a vapor stream from the chamber through the system. The system comprises a contaminant collection unit in fluid communication with the vapor stream. The contaminant collection unit includes a coil and a collection container. The coil is configured to receive cooled gas therein. The arrangement is 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, contaminants in the vapor stream are released from the coil and collected in the collection container. Other embodiments and methods for removing contaminants are further disclosed.
