Optionally, baseband, radio frequency and power management chips are integrated on the main board, Bluetooth, dual SIM card holders and memory card holders are integrated on the SIM card board, and the motor is welded on the SIM card board.

Optionally, a Receiver/Speaker 2-in-1 speaker is set in the mobile phone, and the Receiver/Speaker 2-in-1 speaker adopts a shrapnel contact speaker, and a plastic card holder is arranged between the main board and the SIM card board, and the plastic card holder fixes the speaker. , and form a cavity.

Optionally, the board-to-board connector is 40pin.

Optionally, the storage card holder adopts a push-to-push form.

Optionally, the mobile phone is a slide type.

The utility model provides a space-saving dual-SIM card PCBA main body adopts the form that the main board and the SIM board are separated, so that the structure meets the requirements and at the same time, it also gives PCB main board engineers enough space to rationally layout. The mobile phone adopting the PCBA board of the utility model has a compact and fashionable structure due to the excellent layout, and makes the user feel the practicability of dual-card dual-standby. Since the dual-SIM card holder does not occupy the space of the battery compartment, the battery Increased capacity and extended standby time.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The schematic embodiments and descriptions of the utility model are used to explain the utility model, but not as a limitation to the utility model.

As shown in Figure 1, the present embodiment provides a space-saving dual-SIM card PCBA, the PCBA is composed of a main board 1 and a SIM card board 2, and the main board 1 and the SIM card board 2 are connected by board-to-board The device 3 is connected, and the dual SIM card holder 4 is arranged on the SIM card board 2.

As shown in Figure 2-4, the dual-SIM mobile phone provided by the present embodiment comprises a casing 5, a keypad 6, a dual-SIM card holder 4, and a display screen 7, and the mobile phone is also provided with a PCBA9, and the PCBA is controlled by the mainboard. 1 and a SIM card board 2, the main board 1 and the SIM card board 2 are connected through a board-to-board connector 3, and the dual SIM card holder 4 is arranged on the SIM card board 2.

The main board 1 is separated from the SIM board 2, so that while the structure meets the requirements, the space of the main board 1 is increased, and the layout on the main board 1 can be optimized. In addition, because the dual SIM card holder 4 is arranged on the SIM card board 2 In addition, the dual SIM card holder 4 does not occupy the space of the battery compartment, which increases the capacity of the battery and prolongs the standby time.

Due to the separation of the SIM card board 2 and the main board 1, more functional modules can be arranged on the main board 1 or SIM card board 2, so that the mobile phone can perfectly realize the diversification of mobile phone functions under the function of dual card dual standby In this embodiment, baseband, radio frequency and power management chips can be integrated on the motherboard 1, Bluetooth, dual SIM card holder 4 and memory card holder 8 can be integrated on the SIM card board 2, and the motor is welded on the SIM card board .
