Memory packaging structure of mini SD card

Abstract

A memory packaging structure of mini SD card, the main implementation technology thereof comprises: to perform the pin adjustment to the: memory originally employing TSOP (Thin Small Out-Line Package) packaging structure, eliminating the gap of 0.1 mm to 0.2 mm between the memory and the circuit board, thus completely attached to the circuit board; to leave the top end of the mini SD card open to directly expose the top end of the memory on the surface of the mini SD card, reducing the thickness of a layer of coverage; to cover the pins on the both sides of the memory to hind them, wherein applying glue joint between the auxiliary lateral body and memory pins to enhance the attachment.

Claims

1. A memory packaging structure of mini SD card, comprising: a board;a memory having a plurality of pins at two opposing sides, and connected to a surface of the board through the pins, characterized in that:the memory attached closely to the surface of the board, and two auxiliary lateral body arranged on the two opposing sides for clamping the memory and covering the pins, wherein a surface of the auxiliary lateral body aligned in height to a top end of the memory, such that the top end of the memory directly exposed on an outer surface of the mini SD card.

2. The memory packaging structure of mini SD card of claim 1, wherein an inner layer of the auxiliary lateral body is skew plane.

3. The memory packaging structure of mini SD card of claim 1, wherein the memory is a memory employing the TSOP (Thin Small Out-Line Package) packaging structure.

4. The memory packaging structure of mini SD card of claim 1, wherein an inner layer of the auxiliary lateral body is in a shape of skew plane or step-wise plane or irregular plane, which can be glued with the pins of the memory.
