Abstract: A multi-zone thermal process system utilizing nonfocused infrared panel emitters. An insulated housing has a plurality of zones each having separate panel emitters which heat a product load traveling through the zone and in close proximity to said panel(s) at different peak wavelengths in each zone. The panel emitters emit infrared wavelengths in the middle and far regions. The temperature differences across each zone and between the panel and product are held to a minimum. A specific application of the system is for accomplishing reflow soldering of surface mount devices to printed circuit boards.

Abstract: Apparatus for soldering printed circuit panels includes a roll configuration to convey the panels horizontally across a container carrying molten solder. The printed circuit panels are immersed in molten solder when they pass through the roll configuration. At least one air knife located at the output side of the roll configuration serves to level the molten solder on the panels as they exit from the rolls.

Abstract: Apparatus augmenting a wave soldering machine for mitigating warpage of a printed wiring board after it is processed by the soldering machine comprises heat dissipation means (200) and cooling means (202). The dissipation means directs a first gaseous stream over the a narrow, transverse strip on the underside of the board as it exits a crest of molten solder supplied by the soldering machine. The stream solidifies any liquid solder without disturbing the solder joints. The cooling means directs a second gaseous stream to substantially the centerline region of the board as it exits the dissipation means. The seriatim arrangement of heat reduction means produces a cooling characteristic which is the inverse of the temperature characteristic caused by the soldering operation.

Abstract: A method for dip-soldering circuit boards as, for example, ceramic substrates upon which are formed thin or thick film circuits and to which components are to be attached as, for example, miniature ceramic capacitors in which the components are attached to the board with their longitudinal axes extending in the same direction and with the portions of the conductive films to be attached to the components formed on the board so as to be right angles to the longitudinal axes of the components and wherein the board is dipped into the solder bath with an orientation such that the components are on the under-side of the board as it is emersed with the longitudinal axes of the components extending substantially horizontal and with the plane of the circuit board making an angle of approximately 45* with the surface of the solder bath. Portions of the conductive film may be treated to concentrate the solder in desired locations.

Abstract: A fixture is described herein which is suitable for soldering or desoldering multiple electrical connections as might be found on a printed circuit board or on a printed wiring tape. The disclosure includes in combination a container made from a nonwetting material such as 303 Stainless Steel, connected to a source of heat such as a standard soldering iron or small solder pot. The container includes a cavity into which the solder is placed. This cavity is surrounded by a reservoir ledge which acts to restrain the overflow of solder when the leads to be soldered or unsoldered are immersed therein.
