すという欠点があった。In the conventional flexible cable described above, the contact terminal part 2 of the flexible cable 1 is connected to the terminal part 7 of the printed circuit board 6.
When trying to connect by melting solder, the contact terminal part 2 of the flexible cable is covered with a cover lay film 2.
Since the flexible cable is covered by a coverlay film 2, the heat generated when heating with a soldering iron 9 or the like is dissipated by the coverlay film 2, and the heat transmitted to the contact terminal portion 2 of the flexible cable is small.
For this reason, the solder 8 supplied between the contact terminal part 2 of the flexible cable and the terminal part 7 of the printed circuit board is melted.
＜There was a drawback that it took a lot of man-hours to connect the two by melting the solder, and the connection did not work well, resulting in poor connection between the two.
またフレキシブルケーブルの接触端子部間にはんだ過剰
等によるショートが発生するとこれを修正するのに多大
な工数を必要とするという欠点があった。Furthermore, if a short circuit occurs between the contact terminal portions of the flexible cable due to excessive solder, etc., there is a drawback that a large number of man-hours are required to correct the short circuit.

る。The flexible cable shown in Figures 1(a) and (b) is
It has a contact terminal part 2 connected to a terminal part of a printed circuit board, and is composed of a coverlay film 4 and a base film 5, which sandwich and fix a pattern connected to the contact terminal part 2 from above and below. Further, in the present contact terminal section 2, the cover lay film 4 and the base film 5 are removed, and a terminal section window 3 is provided that exposes the contact terminal section 2.

る。This flexible cable is connected to a printed circuit board 6 having a terminal portion 7 at a position compatible with the contact terminal portion 2 of the flexible cable 1. At this time, the terminal section 7 of the printed circuit board 6
It is assumed that solder 8 is supplied in advance by solder plating or the like to connect both the contact terminal portion 2 of the flexible cable and the printed circuit board terminal portion 7 by melting.

融される。This is shown in FIGS. 2(a), (b), and (c). Second
As shown in Figure (c), it is possible to heat the contact terminal section 2 of the flexible cable directly below with a soldering iron 9, and the solder 8 supplied between the main contact terminal section 2 and the printed circuit board terminal section 7 is heated. Heat is easily transferred to the solder 8, and the solder 8 is melted.
