Abstract: A process and solution is disclosed for removing resin bleed from leads of an encapsulated electronic component in which the component is positioned in an aqueous bath having dissolved therein glycerol and a phosphate salt selected from the group consisting of an alkali metal or ammonium phosphate, polyphosphate or pyrophosphate salt. The component is cathodically connected in an electric circuit enabling electrical current to pass through said component.

Abstract: Disclosed is an in-line electrolytic deflash system and method for removing resin bleed and other materials from the leads of an encapsulated electronic component. An encapsulated electronic component is carried on a continuous belt through the system. The component first passes through an electrolytic deflash station which includes tanks filled with a deflash solution for loosening the resin bleed. The component is then rinsed in a low pressure rinse station, and then carried through a high pressure rinse station where the loosened resin bleed is removed from the component. The component is then further rinsed with both tap water and a deionized water. Once the component has been sufficiently rinsed any remaining moisture is blown off the part in an air knife station and the component is then passed through a dryer which completely removes any moisture remaining on the component.

Abstract: Improved apparatus for carrying encapsulated electronic components, having a conveyor belt defined by a horizontal web with a pluraity of identical, flexible tines depending from both sides of the edge of the web. The web is formed into a continuous, endless loop adapted to be carried on a pair of vertical pulleys rotatable on horizontal shafts. Projecting cams, on the face of the web of the belt remote from the dependent tines, engage mating indentations in the periphery of the two pulleys guiding and imparting movement to the belt. The opposing groups of tines are urged apart, by spreader cams, at the beginning and end of the passage of the belt between the lower faces of the two pulleys. Parts to be plated are brought into the space between the tines which, upon exiting from the cams as the conveyor moves entrap the part between them and causing them to move through the plating tanks and treatment stations positioned along the path of the conveyor.

Abstract: An improved transport belt is provided for gripping and carrying parts such as thin and fragile electronic components through production processes including, for example, electroplating steps and the like. The transport belt comprises an elongated upright web carrying a succession of depending gripper units, each including first and second fingers for gripping and carrying the production parts. The first finger is formed generally coplanar with the belt web, whereas the second finger has a generally U-shaped configuration with depending legs on the leading and trailing sides, respectively, of the first finger. The legs are deformed laterally from the plane of the belt web and interconnected at their lower ends by a cross bar which is urged by the legs into spring-loaded contact with the lower end or tip of the first finger.
