Embodiment Construction

[0016] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0017] As shown in the figure, a new AF camera module motor PIN pin connection method includes the following steps:

[0018] S1. Hollow out the middle of the VCM pad 2 on the FPC board 1 to form a set of concave portions 5 for the contact of the motor PIN pin 4 on the AF camera module HOLDER3;

[0019] S2. Coat the surface 4 of the motor PIN pin with liquid conductive adhesive, and insert it into the recess 5 of the VCM pad 2;

[0020] S3. The liquid conductive adhesive is solidified by high temperature heating, so as to realize the tight connection between the VCM pad 2 and the PIN pin 4 of the motor.

[0021] In another technical solution, the recessed portion 5 in S1 is a stepped struct...

Abstract

The invention discloses a novel AF camera module motor PIN connection method, which comprises the following steps: S1, hollowing the centers of VCM bonding pads on an FPC board to form a group of concave parts for the motor PINs on an AF camera module HOLDER to contact; S2, coating the surface of the motor PINs with a liquid conductive adhesive, and inserting the motor PINs into the concave parts of the VCM bonding pads; and S3, solidifying the liquid conductive adhesive by high-temperature heating to realize tight connection between the VCM bonding pads and the motor PINs. According to the method, the cost is saved, the rosin joints are avoided, and the product yield is improved. The hollowed-out bonding pads are designed in a stepped mode, excessive adhesive can overflow to the upper step of the hollowed-out bonding pads, and the conductive adhesive is prevented from overflowing to the board surface. The use amount of the conductive adhesive is controlled, the adhesive is drawn strictly according to the specified use amount, and excessive overflow of the conductive adhesive is prevented; and the FPC board surface around the bonding pads is coated with ink, so that the short circuit of the module cannot be caused even if a small amount of adhesive overflows.

Description

Technical field: [0001] The invention relates to the technical field of AF camera modules, in particular to a novel AF camera module motor PIN pin connection method. Background technique: [0002] The traditional AF camera module is to weld the motor PIN pin to the motor pad of the FPC board to realize the connection between the two. This method requires specific welding equipment and increases labor costs. And sometimes there will be virtual welding, which will affect the AF function of the module. Invention content: [0003] In view of the above-mentioned problems, the purpose of the present invention is to provide a new AF camera module motor PIN pin connection method. [0004] The object of the present invention is achieved through the following steps: [0005] S1. Hollow out the middle of the VCM pad on the FPC board to form a set of concave parts for the contact of the motor PIN pin on the AF camera module HOLDER; [0006] S2. Coat the surface of the motor PIN pi...
