Patent ID: 8305768

Claim:
A lead mounting method of mounting, onto a mounting surface of a printed board, a pair of L-shaped leads to be connected to an anode terminal and a cathode terminal of a secondary battery, respectively, said method comprising: preparing two flat leads, each of which has a mounted part having an outer lower surface to be disposed on the mounting surface of the printed board and a connected part to be connected to one of the anode terminal and the cathode terminal; bending each of the two flat leads into an L shape so that the mounted part and the connected part of each of the two leads are perpendicular to each other to obtain the L-shaped leads; and connecting and fixing all of the outer lower surface of the mounted part of each of the L-shaped leads onto the mounting surface of the printed board by soldering; wherein after bending each of the two flat leads into the L shape to obtain the L-shaped leads and before connecting the connected part of each of the L-shaped leads to one of the anode terminal and the cathode terminal of the secondary battery, all of the outer lower surface of the mounted part of each of the L-shaped leads is connected and fixed onto the mounting surface of the printed board by the soldering; and wherein the connecting and fixing comprises connecting and fixing all of the outer lower surface of the mounted part of each of the L-shaped leads to a land formed on the mounting surface of the printed board by the soldering, so that all of the outer lower surface of the mounted part of each of the L-shaped leads has a length in a bending direction that is not greater than a length of the land.
