[0014] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model.

Detailed Implementation Methods

[0015] Please refer to Figure 1-2 and Figure 4 As shown, this utility model discloses a circuit board assembly 100, applicable to LGA / LGA type sockets, including a circuit board 10, a plurality of conductive sheets 111 attached to one side surface of the circuit board 10, and a cover 20 on the same side as the conductive sheets 111. The conductive sheets 111 are arranged in a matrix to form conductive areas 11. The cover 20 is shaped to fit the conductive areas 11, and a locking structure exists between the cover 20 and the circuit board 10, allowing the cover 20 to move relative to the circuit board 10 to open and close the conductive areas 11. Preferably, The conductive sheet 111 is gold-plated, and the lower surface of the cover 20 has an upwardly formed recess 23. This recess 23 can form a receiving space 20 with the circuit board 10, in which the conductive sheet 111 is housed. In this way, the conductive sheet 111 in the conductive area 11 can be effectively protected when the circuit board assembly 100 is transported or in standby mode, avoiding accidental scratches or peeling of the plating. In addition, in specific applications, the opening and closing degree of the cover 20 can be adjusted according to the size of the electrical contact area of ​​the mating connector to maximize the protection of the conductive area 11.

[0016] Please refer to Figure 2-4 As shown, at least one side of the cover 20 extends an operating part 21. A locking structure is connected between the lower surface of the operating part 21 and the circuit board 10. The lower surface of the operating part 21 or the circuit board 10 has a first joint 212, and the other has a second joint 12 adapted to the first joint 212 to form a locking structure. In this embodiment, the first joint 212 is a protrusion, and the second joint 12 is a positioning hole. An operating part 21 extends from both sides of the cover 20. The free end of the operating part 21 protrudes upward from the ear 22. The lower surface of the operating part 21 has a protrusion, and the circuit board 10 has a positioning hole. During installation, hold the two ears 22, align the protrusion of the first joint 212 with the positioning hole of the second joint 12, and press the two operating parts 21. The protrusion will forcefully interfere into the positioning hole to complete the cover installation.

[0017] The circuit board assembly 100 typically operates in a confined space. When the cover 20 is detachably fitted onto the conductive area 11, the locking structure must be foolproof. Please refer to... Figure 2-3 As shown, the shapes of the first joints 212 on both sides of the cover 20 are different. In this embodiment, the diameters of the protrusions are different, which makes the cover 20 have a foolproof effect. Preferably, the upper surface of the operation part 21 has a foolproof mark 211. The shape of the foolproof mark 211 is the cross-section of the first joint 212. When several circuit board assemblies 100 are joined together, the circuit board 10 can use different second locking parts 12. By observing whether the shape of the foolproof mark 211 corresponds to the second locking part 12, it can be determined whether the cover 20 is selected correctly.

[0018] The above description is only a partial embodiment of the present utility model, not all of the embodiments. Any equivalent changes to the technical solution of the present utility model made by those skilled in the art after reading the present utility model specification shall be covered by the claims of the present utility model.
