CONSTITUTION:An electronic component 4 is mounted to a printed-wiring board 1. A connection tool 7 is mounted to a terminal 5 of the electronic component 4 protruding from the rear surface, i.e., a copper foil 3, of the printed-wiring board 1; its upper end is brought into contact with the copper foil 3; a part lower than the copper foil 3 is brought into contact with a molten solder; thereby, the copper foil 3 and the terminal 5 are soldered via the connection tool 7. A springy thin sheet is used for the connection tool 7; it is formed to be nearly U-shaped or C-shaped; a diameter of its inscribed circle is formed to be a little slender than a diameter of the terminal 5; a window 9 is formed at an intermediate part between its upper end and a piece 8 which has been bent outward. Thereby, a bonding force of the copper foil 3 and the terminal 5 is enhanced by a solder 6 via the connection tool 7; reliability of a soldering operation is enhanced remarkably.

In the conventional technology, as shown in FIG. 7, after inserting the terminal 5 of the electronic component 4 into a predetermined hole 2 provided in the printed wiring board l,
The terminal 5 and the copper foil 3 were connected by soldering by bringing the lower surface of the printed wiring board l, that is, the copper foil 3 side, into contact with the molten solder. However, in this method, the opposing area between the terminal 5 and the copper foil 3 is small, and the amount of solder 6 adhering to each other is small, so heat generated by energizing the electronic component 4 is conducted from the terminal 5 to the printed wiring board 1. Terminal 5
Stress caused by the expansion of the and printed wiring board l and cooling contraction when the current is not applied is applied as stress to the solder 6 that connects the terminal 5 and the copper foil 3, causing the solder 6 to ring due to metal fatigue due to repeated use over a long period of time. It has the disadvantage that it can be cut into pieces, resulting in poor connection of electronic parts. On the other hand, in order to alleviate this drawback, if a through-hole type printed wiring board is used, the opposing area between iFI Flf and the terminal will increase, and the bonding force between the terminal and the copper foil will increase, which will reduce the problem of solder breakage. Although this problem can be solved, there is a problem in that the through-hole type printed wiring board is expensive and its use significantly increases the cost of the equipment.

(Effects of the Invention) According to the present invention, when mounting and soldering electronic components on a printed wiring board, a connecting tool is mounted on the terminal of the electronic component, and the upper end is connected to the copper foil of the printed wiring board. Since the connecting tool is connected to both the terminal and the copper foil, the bonding strength between the terminal and Mffa is greatly increased, and the risk of solder breakage, which is a disadvantage of the conventional method, can be avoided. The connecting tool is made of a thin springy plate that is approximately U-shaped or C-shaped, and the diameter of the inscribed circle is slightly narrower than the diameter of the terminal, and the upper end is bent outward. By using a coarse wire wound into a rough coil shape, the upper end of which is thicker than the diameter of the terminal, and the lower end slightly thinner than the diameter of the terminal, it is possible to transport the wire while it is attached to the terminal before soldering. Even if the connection tool is installed, the mounting condition of the connection tool does not change, and the structure has a sufficient bonding area for both the terminal and the copper foil, and the structure allows molten solder to easily enter the inside of the connection tool. It can provide strong bonding strength to both the terminal and the copper foil.
