Abstract:
1. A rectification chip terminal structure for soldering a rectification chip encased in a glass passivated pallet (GPP) on a terminal filled with a packaging material to form a secured mounting for the rectification chip to be inserted in a coupling bore of a circuit board, comprising: a conductive element located above the rectification chip including a base soldered on a back side of the rectification chip having a boss to form a space to prevent the GPP from fracturing when the packaging material is heated and expanded, a root extended upwards from the base having one end connecting to a buffer portion which has a helical structure to prevent bending and deformation under external forces; and a base seat formed in a cup shape for holding the rectification chip having a housing space and a deck for soldering the rectification chip, the deck being surrounded by a spacer zone which is an annular groove to form a stress buffer zone, the spacer zone having a bending design to prevent moisture from seeping in through an inner wall of the terminal, the inner wall having a bend spot on a upper side to couple with the packaging material and prevent the moisture from seeping in, the base seat further having a first tapered section on a upper peripheral side that forms an inclined angle directing towards the center of the terminal, a second tapered section in a middle portion of the terminal periphery that has an inclined angle depending on the shrinking condition of the first tapered section, and a grip portion on a lower periphery that has a plurality of bulged traces form on the surface thereof and a smooth bottom.
