Problems solved by technology

However, limited by this packaging process, these two types of products after packaging are very large, so after being inserted into the peripheral expansion connector of the terminal device as an accessory device, the wireless network access device cannot be completely included in the terminal device , causing inconvenience to use

Embodiment Construction

[0019] The microSD type wireless network access device of the present invention is a wireless network card with the same size and specification as the standard microSD card, and the microSD type wireless network card has a built-in sending / receiving antenna. The microSD type wireless network access device can be loaded and removed from the microSD card slot in a handheld mobile terminal (such as a mobile phone), and can independently complete the wireless network access function. At the same time, it can communicate with the handheld device through the SDIO interface Exchange data and commands.

[0020] figure 1 It is a side sectional view of a packaged microSD type wireless network access device according to an embodiment of the present invention. The packaged wireless network access device includes a PCB substrate 110 , a chip component 120 , a chip 130 , a plastic packaging material 140 , and a gold wire 150 .

[0021] It should be noted that if the chip in the microSD ty...

Abstract

The invention relates to a method for packaging a microSD wireless network access device. The method comprises the following steps: designing the layout of components in a PCB (printed circuit board) substrate; mounting an SMD (surface mount device) on a solder joint wiring surface of the PCB substrate, then carrying out reflow soldering to cure the SMD; mounting a chip on the solder joint wiring surface of the PCB substrate, then soldering a pad on the chip and signal wires on the PCB substrate together; carrying out plastic package on the PCB substrate subjected to mounting and soldering; then, cutting the PCB substrate subjected to plastic package to obtain a wireless network access device of which the dimensional specification is same as that of a standard microSD card. By using the method provided by the invention, the minimized package of the microSD type wireless network access device can be achieved, so that the packaged device can be completely contained into a terminal. The method provided by the invention is suitable for packaging microSD type wireless network access cards.

Description

technical field [0001] The present invention relates to wireless network access equipment, in particular to the encapsulation technology of wireless network access equipment. Background technique [0002] The wireless local area network (WLAN) has developed rapidly in the past two years. Since the IEEE802.11 standard successfully solved the air interface compatibility problem and promoted the intercommunication between the wireless local area network terminal and the access point, the cost of the wireless local area network equipment has dropped rapidly. With the rapid development of wireless local area network access technologies, wireless network access devices tend to be miniaturized gradually. [0003] At present, the relatively common wireless network access device uses the USB data interface protocol to communicate with the terminal device. This kind of wireless network access device acts as an accessory device and cooperates with the host controller to provide the ter...
