The invention relates to a voice coil motor base and a manufacturing method thereof. The voice coil motor base comprises an insulating base and a metal circuit which is embedded in the insulating base and comprises a plurality of branches, one end of each branch forms a pin end, the other end of each branch forms a welding pin end and a middle connecting section, and the insulating base comprises an upper surface and a lower surface which are oppositely arranged; a supporting block is also arranged to be embedded in the insulating base, the supporting block wraps and is fixed on the connecting section of the branch, the supporting block comprises two supporting surfaces which are horizontally and oppositely arranged, and the two supporting surfaces are respectively and correspondingly exposed on the upper surface and the lower surface of the insulating base. The closed complete cavity is formed by clamping and positioning the top / bottom supporting surface to form the voice coil motor base with a flat surface, so that the metal circuit can be prevented from being oxidized and corroded by the outside due to the fact that part of the metal circuit is exposed by the centre hole.
Description
technical field [0001] The invention relates to the technical field of a voice coil motor base and a manufacturing method thereof, in particular to a voice coil motor base used in the field of electronic equipment and a manufacturing method thereof. Background technique [0002] The existing voice coil motor base and the voice coil motor thereof usually include an insulating base and a metal circuit injected into the insulating base. The metal circuit includes several branches for electrically welding various electronic components. In the prior art, when metal circuits are injection-molded, ejector pins or other support elements are usually used to position / support the metal circuits, so as to facilitate the injection molding of insulating bases made of plastic on the metal circuits. The voice coil motor base formed by this positioning method will form ejector pin holes / support holes after removing ejector pins or other supporting elements. The base with thimble holes / suppo...
