摘要： System and methods for solder flux removal from a gas stream is disclosed. In one aspect, the system includes: a scrubber chamber having a gas inlet and a gas outlet through which the gas stream is introduced into and withdrawn from the scrubber chamber; at least one rinse agent delivery mechanism for introducing a rinse agent into the scrubber chamber for contact with the gas stream, the rinse agent being at a temperature for condensing a first portion of the flux from the gas stream; a condenser portion of the scrubber chamber containing the rinse agent for receiving the gas stream, the rinse agent being at a temperature for condensing a second portion of the flux in the gas stream; and a condensed flux removal apparatus adapted for removal from the scrubber chamber of at least a portion of the rinse agent and the flux which has condensed.

摘要： A high temperature conveyor belt is provided having a non-metallic conveying surface which will not scratch, abrade or otherwise mar the surface of a product being carried on the belt through a furnace and which will not contaminate the product. In one embodiment, the conveyor comprises a high temperature fabric belt attached to a metal belt which may be a conventional woven metal conveyor belt. In another embodiment, the conveyor is composed of a non-metallic high temperature strand which is woven or threaded through a metal belt to provide a non-metallic conveying surface. In a further embodiment, the non-metallic product support elements are coupled to roller chains at each side of the furnace chamber and which are cooperative with a drive mechanism to transport the conveyor through the furnace. The roller chains can be located outside of the furnace chamber to avoid exposure to the high temperature of the furnace chamber.

摘要： A furnace system for thermal processing of products and materials is disclosed which is particularly useful in processing touch screens for computer tablets and silicon wafers employed in fabricating solar cells. The system employs a hybrid of microwave and radiant heating of workpieces to provide controlled heating of the workpieces. A plurality of susceptors are disposed a furnace chamber. A plurality of microwave sources are arranged to provide microwave radiation in the chamber to uniformly heat workpieces in the chamber and to provide uniform heating of the susceptors. The susceptors are effective upon microwave heating by the microwave sources to provide uniform radiant heating of the workpieces in the chamber.
