Process for manufacturing memory card

Abstract

The method comprises: the contact terminal processed with mold forming is placed on the injection molding machine to make plastic injection so as to make the injected base-seat to cover the contact terminal; embedding the memory card chip (including flash memory, control chip and passive component) into said base-seat; making a plastic injection for the whole assembly to make the chip module entirely and closely covered.

Description

technical field [0001] The invention relates to a manufacturing method of a memory card, especially a storage medium used for data storage, deletion, etc. of a computer or its peripheral equipment. Background technique [0002] By the way, today's computer technology is growing at an ever-changing speed. Memory cards have become a carry-on item for many computer users. They are mainly used as storage media for digital peripheral products. Compared with disks, memory cards are small in size but high in capacity. It is much larger than the disk, and the access speed is fast. In addition, the memory card is not easy to get wet or damaged like the disk. Therefore, it has gradually replaced the small capacity and large disk. [0003] At present, in order to cooperate with different models of digital products or computer peripheral equipment, the industry has launched memory cards of various sizes and specifications for storage, reading, and deletion of various computer devices. ...

Problems solved by technology

[0005] 1. The contact terminals used for signal output / input are made of metal copper sheet through continuous die molding, and then placed on the front of the memory card base made of plastic injection. Because these processes still need to be stamped Good contact terminals are positioned on the base, and the assembly process is cumbersome, and the defect rate is often increased due to human negligence

[0006] 2. As for the memory card made of the base and the cover, the memory packaging components covered in it cannot be completely isolated from the outside world, and are prone to moisture, resulting in insufficient reliability and durability of the memory card, as well as falling off scale , although some companies use fillers to fill the space in the memory card, such as Taiwan's new patent No. 556908 "improved structure of the memory card" to prevent moisture from entering and affecting the reliability of the memory card, but the manufacturing process is cumbersome and expensive. Increase the lack of production costs
