Base welded with electronic components and voice coil motor thereof

Abstract

The invention provides a base welded with electronic components. The base comprises at least two electronic components, at least two metal circuits and an insulating base, wherein each metal circuit is connected with at least one electronic component, each metal circuit comprises a plurality of branches, an inner end of each branch forms a welding portion, the plurality of welding portions of the plurality of branches are connected with the plurality of pins of the electronic component in a one-to-one correspondence manner; the insulating base is coated and molded with at least two metal circuits so as to position all the branches; and before at least two metal circuits are coated and formed, each metal circuit is connected to a first material strap and a second material strap, the first material strap is arranged outside the at least two metal circuits in a surrounding mode, the second material strap is located between the at least two metal circuits, at least one branch of a plurality of branches of each metal circuit is connected to the first material strap and the second material strap at the same time, and the other branches are connected to the first material belt.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a voice coil motor. Background technique [0002] The camera module is an important part of electronic devices with camera functions such as mobile phones and tablet computers. A camera module generally includes a printed circuit board (PCB), an image sensor, a support base, a voice coil motor, and a lens. Both the image sensor and the support seat are arranged on the printed circuit board, the voice coil motor is arranged on the support seat, and through holes are arranged on the voice coil motor and the support seat, and the lens is connected with the voice coil motor, and is positively connected to the image sensor through the through hole. pair settings. A filter for blocking the through hole is adhered on the support base. The support seat increases the height of the camera module, which is not conducive to the development of thinner and lighter electronic equipment su...

Problems solved by technology

In this patent, the base B is formed by secondary injection molding technology, and a certain angle is formed between the retaining wall B2 and the body B1. The retaining wall B2 and the body B1 are only combined through one surface. Not only is the combination between the two unreliable, but also Moreover, only a driving mechanism with one three-dimensional circuit E can be molded at a time, and the molding efficiency is low
