Description

TECHNICAL FIELD

[0001] The utility model belongs to electronic equipment technical field, especially a kind of metal mainboard. BACKGROUND

[0002] In electronic equipment, especially in highly integrated products such as smart phones, the core role of metal mainboard (usually aluminum substrate) is to efficiently dissipate heat and provide structural support. Its evolution clearly shows this trend: from the early stage as a simple heat dissipation substrate and structural skeleton, to the middle stage as an integrated metal-based circuit board (with a three-layer structure of circuit layer, insulating layer and metal base layer), and then to the modern stage as a highly integrated and structural function integrated middle frame, directly carrying the core heating chip and dissipating heat to the entire device.

[0003] In order to realize the above functions and ensure the stability of the device, the installation method of the metal mainboard is also crucial. The most traditional is mechanical screw fixing, which has the advantages of firmness and reliability. In order to pursue thinness, buckle / slide rail installation appears to save space. Adhesive fixing can achieve full plane contact and maximize heat dissipation efficiency. In modern devices, it is more common to use a hybrid installation method, that is, to use screws as the main fixing at key points and to be supplemented by buckle positioning and adhesive of heat-conducting materials, so as to balance between reliability, heat dissipation and maintainability.

[0004] However, despite the continuous progress of design and installation technology, there is a fundamental technical bottleneck in the metal mainboard—the technical problem of fixed installation format. This means that once the mainboard is produced, its physical form, size and the location of all fixing points cannot be changed. This problem directly leads to a lack of flexibility in device design, and any minor change may trigger the redesign of the mainboard, greatly increasing the iteration cost and cycle. At the same time, fixed screw holes and buckle slots occupy valuable board space, limit internal layout optimization and battery expansion, and seriously hinder the development of modular design, making it impossible for users to freely upgrade specific modules and increasing the difficulty of finding compatible replacement parts during later maintenance. Therefore, this problem is a key challenge that must be faced and solved in the pursuit of higher integration, better space utilization and stronger functional flexibility in current electronic devices.
