Embodiment Construction

[0027] The principles and features of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention. For those of ordinary skill in the art, all embodiments obtained according to the spirit of the present invention shall belong to the protection scope of the present invention without any creative effort.

[0028] The modification of PCBA of electronic products is often only focused on the parts that need to be upgraded. Among them, the CPU part has the highest replacement frequency, while the upgrade of the interface part is relatively slow. Therefore, the present invention realizes the CPU part and the interface part of the electronic product with one PCB respectively. In this way, when most interface parts do not need to be modified, only the PCB where the CPU part that needs to be upgraded is modified, which c...

Abstract

Embodiments of the invention relate to a circuit board and a manufacturing method therefor. The circuit board comprises an interface board and a CPU board, wherein the interface board is a first printed circuit board used for placing an interface circuit; the CPU board is a second printed circuit board used for placing the CPU and related circuits of the CPU; and the CPU board is detachably connected with the interface board. According to the circuit board, the frequently-upgraded CPU and the related circuits, and the relatively rarely-upgraded interface circuit are placed on the two mutually-independent PCBs, so that when any one of the CPU and the related circuits, and the interface circuit need to be upgraded, the corresponding PCB is modified without requiring to modify the PCB of the whole product; and therefore, the cost of the product is greatly lowered, the modifying time can be reduced, and the manpower resource can be saved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a circuit board and a manufacturing method thereof. Background technique [0002] In today's era, people's life is inseparable from various electronic products, and the production of these electronic products is inseparable from PCB (Printed Circuit Board, printed circuit board). PCB is an important electronic component. It is the support of electronic components and the carrier of electrical connection of electronic components. After electronic products adopt PCB, due to the consistency of similar PCBs, errors in manual wiring are avoided, and automatic insertion or placement of electronic components, automatic soldering, and automatic detection can be realized, ensuring the quality of electronic products and improving labor efficiency. productivity, reduced costs, and ease of maintenance. [0003] The complexity of the PCB often depends on the outlet of...
