摘要： A solder reflow convection furnace (10) employing flux collection and heating to minimize flux and solvent build up and gas densification to reduce input gas flow is disclosed. As solder melts in the furnace, an effluent of vaporized flux is driven off and can condense on cooler components. To minimize such condensation, the gas is directed through a cooling system (306) in which the flux condenses, and the cooled, cleaned gas is directed into the furnace's product cooling section. When the furnace employs a gas amplifier (302), the recirculating gas is cooled prior to reentry into the heating chamber (34), which increases its density and removes flux by condensation. Upon reentering the heating chamber, the cooler, denser gas undergoes a greater expansion than would return hot gas, thereby increasing the pressure in the chamber and correspondingly increasing the velocity of the output flow to the process area.
摘要翻译：公开了一种采用助熔剂收集和加热以最小化通量和溶剂累积以及气体致密化以减少输入气流的焊料回流对流炉（10）。当焊料在熔炉中熔化时，蒸发的焊剂的流出物被排出并可以冷却在较冷的部件上。为了最小化这种冷凝，气体被引导通过其中助熔剂冷凝的冷却系统（306），并且被冷却的清洁气体被引导到炉的产品冷却部分中。当炉采用气体放大器（302）时，再循环气体在再入入加热室（34）之前被冷却，这增加了其密度并通过冷凝来消除通量。在重新进入加热室时，冷却器，更致密的气体经受比返回热气体更大的膨胀，从而增加了室中的压力并相应地增加了输出流到处理区域的速度。

摘要： An infrared furnace system provides for adjusting the amount of time a workpiece spends in a respective section of the furnace while at the same time minimizing the footprint, i.e., the amount of floor space that the furnace uses. Various embodiments allow for optimizing the required thermal duration of each section which then also optimizes the heating and/or cooling profile within each section. Transfer conveyors are provided to transfer a workpiece from one conveyor operating at a first speed to a second conveyor operating at a second speed, different from the first speed in order to prevent damage to the workpiece. Rollers are provided to support the workpiece and to maintain a proper orientation. A heating lamp support assembly provides power to the lamp and facilitates exchange and replacement of the lamp. An air delivery system provides process gas maintained at the correct temperature. An exhaust system provides air flow with improved turnover and reduced noise considerations. Infrared heating lamps are cooled by providing gas flow across the end terminals. The wavelength of light emitted by the heating lamps is adjusting by controlling parameters of the process gas being introduced into a section of the furnace.

摘要： The present invention provides a system and method for binder removal and sintering of materials such as ceramic materials and products, LTCC intervals, solid oxide fuel cells and powder metals. A combination of microwave and convection/radiation heating is employed for binder removal and sintering. Preferably, the microwave heating is accomplished using a variable or multi-frequency microwave source. A gas atmosphere is provided in the furnace chamber by one or more eductors which produces a high volume gas circulation in the furnace chamber to achieve a highly uniform gas environment and temperature. The process in accordance with the invention controls the heating cycle, the heat sources and thermal profile depending upon the composition of the particular material being processed. The thermal processing can be accomplished in a batch furnace in which a product is loaded for processing and unloaded after processing. The invention can also be practiced in a continuous process wherein the product is conveyed between furnace sections or chambers of a furnace.
