COIN TYPE ELECTRIC ELEMENT AND PRINTED BOARD MOUNTING COIN TYPE ELECTRIC ELEMENT

摘要

PPROBLEM TO BE SOLVED: To surely stably solder a coin type electric element to a printed board by remarkably miniaturizing a mounting area. PSOLUTION: The printed board on which the coin type electric element is mounted has the coin type electric element 1 and the printed board 2 to which the coin type electric element 1 is soldered. The coin type electric element 1 is formed by sealing an opening part of a coin outer can 3 formed by working metal in a coin shape with a sealing plate 4 through an insulating seal 7, and the coin outer can 3 and the sealing plate 4 act as a pair of electrodes. A lead plate 6 is connected to a second electrode surface 5B of the coin type electric element 1, the tip part of the lead plate 6 is bent toward the surface of a first electrode surface 5A, and a solder surface 14 for fixing with reflow solder is installed at the tip part of the lead plate 6.
