Problems solved by technology

However, when the conductor spacing in the flexible flat cable is less than 0.5mm, it is easy to cause the phenomenon that the amount of tin brushed on the printed circuit board cannot be accurately controlled when the flexible flat cable is soldered to the printed circuit board, resulting in soldering short circuit and other conditions.

Embodiment Construction

[0016] see figure 1 , the flexible flat cable assembly 1 of the present invention includes a flexible flat cable 2 and a printed circuit board 3 welded together with the flexible flat cable 1 .

[0017] see figure 2 , the flexible flat cable 2 includes a plurality of conductors 21 arranged in parallel and at intervals in the transverse direction and an insulator 22 covering the conductors 21 . The insulator 22 of the flexible flat cable 2 is provided with a gap 221 so that a section of the conductors 21 in the longitudinal direction is exposed outside the insulator 22 in the vertical direction, and a free end of the conductors 21 is still covered by the insulator 22 . The distance ( D1 ) between two adjacent conductors 21 in the plurality of conductors 21 is less than 0.5mm, and the specific value can be set as 0.5mm, 0.4mm, 0.3mm, 0.2mm and other values. When the distance ( D1 ) between two adjacent conductors 21 is 0.5 mm, the width ( D2 ) of the conductors 21 is 0.3 mm. ...

Abstract

The invention discloses a flexible flat cable assembly (1), which comprises a flexible flat cable (2) and a printed circuit board (3) electrically connected with the flexible flat cable. The flexible flat cable comprises a plurality of conductors (21) which are transversely arranged in parallel and an insulator (22) coated outside the plurality of conductors; the insulator is provided with a notch section (221), so that the conductors in the flexible flat cable are exposed outside the insulator in a vertical direction; the printed circuit board is provided with a plurality of conducting strips (3) electrically connected with the conductors respectively; a distance between two adjacent conductors is the same as a distance between two adjacent conducting strips; and the width of each conductor is larger than that of each conducting strip.

Description

【Technical field】 [0001] The invention relates to a flexible flat cable assembly and an assembly method thereof, in particular to a method for soldering a flexible flat cable to a printed circuit board. 【Background technique】 [0002] With the miniaturization of the distance between the terminals in the electrical connector assembly, the distance between the conductors in the flexible flat cable electrically connected to the terminals in the electrical connector assembly also becomes smaller. In the prior art, before welding the flexible flat cable to the printed circuit board, tin wire or tin paste needs to be added on the soldering piece of the printed circuit board as solder. However, when the conductor spacing in the flexible flat cable is less than 0.5mm, it is easy to cause the phenomenon that the amount of tin brushed onto the printed circuit board cannot be accurately controlled when the flexible flat cable is soldered to the printed circuit board, resulting in solde...
