[0014] Figure 3 is an exploded view of the DDR4 memory slot according to the present application;

[0015] Figure 4 is a structure schematic view of the DDR4 memory slot according to the present application. DETAILED DESCRIPTION

[0016] The present application will be further described below in combination with the accompanying drawings and examples.

[0017] Example 1:

[0018] The present example proposes a DDR4 memory slot ball mounting terminal structure, which mainly comprises: a ball mounting terminal body 1 and a groove 2 arranged at the end of the ball mounting terminal body; the number of the groove 2 can be one or more, when there are multiple grooves 2, the grooves 2 can be arranged in parallel at the end of the ball mounting terminal body, or can be arranged vertically at the end of the ball mounting terminal body. The groove 2 of the present example can be arranged on both front and back surfaces of the end of the ball mounting terminal body. The present example can greatly improve the holding force of the tin ball after tin ball implantation by increasing the groove 2, thereby avoiding tin ball falling off.

[0019] Meanwhile, the present example is provided with a notch 3 at both sides of the end of the ball mounting terminal body, the shape of the notch 3 can be circular arc, rectangular or triangular, by increasing the notch 3, the holding force of the tin ball can be greatly increased after tin ball implantation, thereby avoiding tin ball falling off. The end of the ball mounting terminal body of the present example is in a chamfered structure.

[0020] Example 2:

[0021] As Figure 3 and Figure 4As shown, on the basis of embodiment 1, the embodiment provides a DDR4 memory slot, which mainly comprises a housing plastic body 101, a locking 102, a harpoon foot 103, a solder ball terminal 104, a solder ball 105 and a PCB board 106; the locking 102 is installed at both ends of the housing plastic body 101, the harpoon foot 103 is installed in the slot hole at both ends of the housing plastic body 101, the solder ball terminal 104 is installed in the Pin hole of the housing plastic body 101, the solder ball 105 is welded to the soldering plate part of the solder ball terminal 104, and the PCB board 106 is welded and connected with the solder ball 105.
