Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings.
[0014] The flexible circuit board and wire welding process of the present invention, the specific operation steps of its production process are as follows:
[0015] Such as figure 1 As shown, the outer skin of one end of the lead wire 1 is peeled off by 2-5 mm with a special clamp to expose the four wires 2 in the lead wire 1;
[0016] Such as figure 2 As shown, the four guide wires 2 are respectively inserted into the four positioning holes of the positioning plate 3, the position of the positioning plate 3 must be corrected, otherwise it will affect the correct position of the guide wire 2, and the guide wire 2 Exposing the surface of the positioning plate 3 by 1-2mm;
[0017] Such as image 3 , Figure 4 As shown, the transition section from the lead wire 1 to the wire 2 is put into a mold for injection molding to form a fixed boss 4, and the four wires 2 are ...

The invention discloses a flexible circuit board and a conductor welding technology. The production technology specifically comprises the following operation steps of: stripping an outer skin on one end of a lead by 2-5 mm, and exposing four conductors in the lead; respectively inserting the four conductors into four positioning holes in a positioning plate, wherein the conductors are exposed from the surface of the positioning plate by 1-2 mm; putting a transition section between the lead and the conductors into a die for injection moulding, forming a fixed boss, uniformly fixing the four conductors into the boss along the circumferential direction, and taking the positioning plate down; stripping the outer skin of the parts, exposed from the boss, of the conductors, exposing internal copper wires, and uniformly dipping the four copper wires in tin; and respectively inserting the four copper wires after the tin dipping into four holes in a reinforcing plate of the flexible circuit board, cutting out the redundant copper wires exposed from the surface of the circuit board, and carrying out welding respectively on four points. According to the invention, the rejection rate in the welding process of the flexible circuit boards and the conductors is substantially lowered, and specifically, the rejection rate is reduced from the former 10% to 6%.
Description
technical field [0001] The invention relates to the technical field of circuit connection of a vehicle-mounted camera, in particular to a welding process of a flexible circuit board and a wire. Background technique [0002] When the lead wire of the car camera is welded to the flexible circuit board inside the protective cover, the phenomenon that the flexible circuit board is skewed and two or more wires are welded together often occurs. Cause defective rate to be extremely high, improved production cost, reduced production efficiency. Contents of the invention [0003] The object of the present invention is to provide a flexible circuit board and wire welding process that first positions the wire, then fixes it by injection molding, and has accurate welding positioning. [0004] In order to achieve the above object, the technical solution of the present invention is achieved in the following way: the welding process of the flexible circuit board and the wire, the specif...
