板の電極に半田付けしたものである。Means for Solving the Problems In order to solve this problem, the present invention is such that the ends of a flexible substrate are bent so that the conductor pattern is on the outside, and soldered to the electrodes of the substrate.
作用
この方法により、共晶半田のフィレットが大きくなり、
半田付は性が向上し、半田付は強度も強くなることとな
る。This method increases the fillet size of the eutectic solder,
The soldering properties are improved, and the soldering strength is also increased.

In FIGS. 3 and 2, the same parts as those shown in FIGS. 3 and 4 are designated by the same numbers. Reference numeral 8 indicates a connection portion formed by bending the end of the flexible substrate 2 so that the conductor pattern 6 is placed on the outside, and reference numeral 9 indicates a fillet of eutectic solder formed thereby.

予備半田をしておくのが好ましい。According to this embodiment, by bending the end of the flexible substrate 2 so that the conductor pattern 6 is on the outside,
A connection part 8 in which a part of the conductor pattern 6 is exposed is formed at the end of the flexible substrate 2, and a fillet 9 of the eutectic solder 7 is formed.
The thicker the solder, the better the solderability and the stronger the solder. Since the fillet 9 is large, visual soldering can also be done easily. In addition,
Preferably, the eutectic solder 7 is pre-soldered to at least one of the electrode 3 and the conductor pattern 6 before soldering by thermocompression bonding.
