Abstract
The utility model discloses an MINISD multimedia memory card. The utility model comprises a base board, an electronic device and at least one silicon wafer, wherein the electronic device is arranged on the base board, the silicon wafer is in electric connection with the electronic device, the surface of the electronic device and the surface of the silicon wafer are covered by hot resin, an upper shell body and a lower shell body of the memory card are respectively formed by the resin and the base board, one side edge of each shell body is provided with a gold finger splicing groove and both side edges of each shell body are respectively provided with a positioning notch. The MINISD multimedia memory card of the utility model has the advantages of small size and reduced occupied space.
Description
Technical field
The utility model relates to memory storage, is specifically related to a kind of MINISD multimedia storage card.
Background technology
In the prior art, miniature MINISD multimedia storage card has been widely used in communication product and photographic product, because the volume of the said goods is all less, so require the MINISD multimedia storage card outside having big memory capacity, also require its volume energy as far as possible little, reducing to take the inner space of communication product and photographic product, the method for the existing MINISD of making multimedia storage card is as follows: make earlier single MINISD multimedia storage card substrate, mount electron device on the substrate, implanted silicon wafer in each monomer substrate; With silicon wafer and the electron device line that mounts, constitute electrical connection; Adopt hot resin that substrate is carried out the monomer moulding; Make miniature MINISD multimedia storage card.There is following shortcoming in existing method for making: make the MINISD multimedia storage card and adopt the monomer injection molding, the back plate thickness of MINISD multimedia storage card is made of substrate and hot resin compounded, the thickness of MINISD multimedia storage card is excessive, in addition, the efficient of the single mode of production is low.
The utility model content
The purpose of this utility model is, a kind of MINISD multimedia storage card is provided, and the volume of this MINISD multimedia storage card is littler, can reduce its shared space.
The technical scheme that the utility model provides is as follows: construct a kind of MINISD multimedia storage card, comprise substrate, be arranged on the electron device on the substrate, the silicon wafer of a slice at least that is electrically connected with described electron device formation, on described electron device and silicon wafer surface, be coated with hot resin, hot resin and substrate constitute the last lower house of storage card respectively, side at housing has the golden finger inserting groove, has locating notch at the dual-side of housing.
At above-mentioned MINISD multimedia storage card, in substrate, be provided with a slice silicon wafer.
At above-mentioned MINISD multimedia storage card, in substrate, be provided with the multi-disc silicon wafer.
At above-mentioned MINISD multimedia storage card, described substrate is a kind of BT resin component element or FR-5 resin component element.
The utlity model has following advantage: this MINISD multimedia storage card, only be coated with hot resin in the front at storage card, substrate back does not have hot resin to cover, thereby make the thickness of whole M INISD multimedia storage card to reduce, can also adopt the mode that connects substrate to produce more, once can a plurality of MINISD multimedia storage cards of moulding, enhance productivity.

Fig. 1 is the A-A cut-open view of the utility model MINISD multimedia storage card;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the upward view of Fig. 2.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of MINISD multimedia storage card is provided, be provided with substrate, on substrate, be pasted with suitable electron device, on substrate, also be provided with one or more pieces silicon wafers 3, and form with electron device and to be electrically connected, on the surface of electron device 4 and silicon wafer 3, cover the hot resin 1 of last layer, hot resin 1 and substrate 5 constitute the last lower house of storage card respectively, side at housing has golden finger 7 inserting grooves 8, has at the dual-side of housing and be convenient to the locating notch 6 that storage card is located in machine.
Aforesaid substrate adopts BT resin or FR-5 resin to make.
The MINISD multimedia storage card that the utility model provides can be widely used in the mobile phone of digital camera, digital code camera, band expansion slot.
