    摘要： An electrically heated soldering device adapted to simultaneously heat a plurality of spaced electrical elements in a reflow soldering operation includes an elongated metal laminate of substantially U-shaped cross section having a bight portion between two side portions which may be parallel or divergent. The laminate includes a layer of aluminum between a layer of copper and a layer of stainless steel, with the layers being roll bonded together. The copper and aluminum layers are removed at the bight portion to expose the stainless steel layer and form a heat generating zone for contacting the plurality spaced electrical elements which is corrosion resistant and nonwettable by solder. The edges of the copper and aluminum layers adjacent to the exposed stainless steel bight portion are shaped to impart a selectable temperature profile, either uniform or non-uniform along the length of the bight portion. The exposed surface of the stainless steel portion can be provided with a ceramic coating to electrically insulate bight portion from the elements to be soldered. The legs of the U-shaped laminate are adapted to be connected to an electric power source through the copper and aluminum layers thereof.

    摘要： A method and apparatus for positioning a locating mechanism and the artwork frame of a panel processing machine has been devised utilizing a flexible beam apparatus for suspending the panel location mechanism and artwork frame which permit these devices to be moved out of the way during loading and unloading panels into and from the work surface of processing machinery. The flexible beam suspending the location mechanism in the disclosed embodiment comprises two parallel surface thin members of resilient sheet material. These members are each attached along one edge to a rigid portion of the machinery and along an opposing edge to the panel locating mechanism. This flexible beam arrangement permits the locating elements of the locating mechanism to be moved from and restored to a previous position with great accuracy. A pair of co-planar high aspect ratio sheet beam members are used to support the artwork frame. One end of these flexible beams is each attached to the machine and an opposing end is attached to the artwork frame. These flexible beam arrangements permit the locating elements and artwork to be moved while panels are inserted into or removed from a work surface of the processing machine and restored to a previous operative position with great accuracy.

    摘要： Phototools are located for processing both sides of printed circuit board panels by an apparatus and process that utilizes a work station with two alignment fixtures each including panel center registration PCR alignment mechanism to locate phototools and panels. Processing steps utilize the alignment fixtures to locate phototools on both sides of a panel. Each of the two phototools is initially positioned on its alignment fixture by the PCR alignment mechanism and secured to its alignment fixture by means of a vacuum supplied by a vacuum chuck which is operative as the top surface of the alignment fixture. The panel is then placed on top of the first phototool and aligned to the first phototool in the first alignment fixture using the PCR alignment mechanism. This first phototool is then affixed to the first side of the panel. The panel with the attached first phototool is then placed on the second phototool in the second alignment fixture and aligned to the second phototool using the PCR alignment mechanism. The second phototool is then affixed to the second side of the panel. The phototool-panel-phototool package is then placed in a printer for exposure.

    摘要： A process and apparatus are disclosed for controlling losses in volatile working fluid systems. In accordance with the process, the object upon which a work operation is to be effected is sequentially moved from a first sealable chamber to a second such chamber and back to the first chamber. While in the second chamber the object is exposed to a working fluid vapor which elevates the temperature of the object to a level near the boiling point of the working fluid. Thereafter, while still in the second chamber, a substantial portion of the working fluid is drained from the object such that the sensible heat acquired by the object upon its elevation of temperature is sufficient to evaporate working fluid remaining on the object upon its removal to the first chamber. Upon removal of the object to the first chamber the object is thoroughly dried through control of the partial pressure of the working fluid vapor contained within the first chamber atmosphere. This control is effected by a closed devaporization loop coupled to the first chamber. In addition, any working fluid which may have been deposited on surfaces within the first chamber is revaporized by auxilliary heating means. Virtually all of this working fluid vapor is recovered by extended devaporization of the atmosphere. Throughout the process any pressure differentials which exist between an internal atmosphere within the first and second chambers and an external atmosphere are equalized by means of a snorkellike member.
