Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a nested printed circuit board. Background Technology

[0002] Printed circuit boards (PCBs) are the providers of electrical connections for electronic components. With the rise of mobile terminal electronic products, such as smartphones, the spatial requirements for these products are becoming increasingly stringent. Consequently, the requirements for PCBs, as a crucial component of these products, are also increasing, with miniaturization and irregular shapes being among the key requirements.

[0003] Existing printed circuit boards are often fixed with screws or glue during installation. Glue fixation is difficult to remove and leaves residue that is hard to clean. Therefore, screws are mostly used for fixing. However, existing screws require the screwdriver and the screw hole to be aligned on the same axis to unscrew them. Otherwise, the screw surface will wear down, eventually leading to the inability to transmit torque and rendering the board unusable. In some cases, wear may even make the circuit board impossible to remove. This causes inconvenience in the installation of existing printed circuit boards. Therefore, a nested printed circuit board is proposed to solve the problems mentioned above. Utility Model Content
