Description

Technical Field

[0001] The utility model relates to the technical field of PCBA boards, in particular to a compact stacked recorder PCBA module. Background Technique

[0002] With the rapid development of mobile devices and Internet of Things technologies, recorders, as important data acquisition tools, have been widely used in various fields. However, the design of traditional recorders is often limited by internal structures and storage solutions, making it difficult to meet the growing demands for miniaturization, lightweight, and high performance. Specifically, due to the complex internal structures of most recorders, they are relatively large in size and heavy in weight, making them inconvenient to carry and install. Usually, only a single TF card can be installed for data storage without backup. Due to the limited internal space of the recorder, chips and other electronic components are closely arranged, resulting in prominent heat dissipation and electromagnetic interference problems, which affect the stability and service life of the device. In addition, although there are some thin and light recorder products on the market, they often sacrifice storage expandability and heat dissipation performance. Therefore, designing a stacked PCBA board structure for recorders that is both thin, light, and small, can flexibly expand the storage capacity, and has good heat dissipation performance has become one of the urgent problems to be solved in the current market. Content of the Utility Model

[0003] In view of this, the utility model provides a thin, light, and small stacked recorder PCBA module, which can realize the function of quickly replacing the memory card and expanding the storage capacity, while keeping the overall size of the device as small as possible.

[0004] The utility model provides a compact stacked recorder PCBA module, which specifically includes a main board and a secondary board. The secondary board is connected to the main board through a connector and stacked on the main board. A number of chips are integrated on the back of the main board, and components with low heat generation are integrated on the front. The components are wrapped by a shielding cover. One side of the secondary board is attached to the shielding cover, and a number of card slots are provided on the other side of the secondary board.

[0005] For a further description of the foregoing solution, a shielding heat dissipation cover is provided on the back of the main board to wrap the chips. A key switch, a USB connector, and a camera connector are also integrated on the main board.

[0006] Preferably, both the shielding cover and the shielding heat dissipation cover are made of metal covers, which can not only improve the heat dissipation ability but also shield electromagnetic interference (EMI) to improve the stability and performance of electronic products.

[0007] Optionally, two TF card slots and a SIM card slot are integrated on the secondary board. Using dual TF cards can achieve capacity expansion and backup to better protect data security. Equipped with a SIM card, wireless communication functions can be realized to achieve wireless data transmission.

[0008] Furthermore, all components of the auxiliary board are arranged on one side of the card slot, and a metal heat sink is arranged on the other side of the auxiliary board to fit with the shielding cover of the main board, improving the fitting degree, facilitating heat dissipation, and reducing the overall thickness.

[0009] Compared with the prior art, the utility model realizes the miniaturization and lightweight of the recorder, provides flexible storage expansion ability, improves the heat dissipation performance, reduces electromagnetic interference, and improves the stability and service life of the recorder.

[0010] The utility model solves the problems of large volume, poor storage expandability and poor heat dissipation performance of the recorder PCBA board in the prior art. The utility model has the advantages of miniaturization, lightweight, strong storage expandability and good heat dissipation performance, and can be widely applied to mobile devices and Internet of Things technologies, with high practical value.
