Problems solved by technology

[0003] However, in the process of coating the upper surface of the body with a metal layer, the surface of the bump is also coated with a metal layer, so when the chip module is supported on the bump, it is located on the top surface of the bump. The metal layer will contact the chip module, causing the chip module to short circuit

Embodiment Construction

[0038] In order to facilitate a better understanding of the purpose, structure, features, and effects of the present invention, the present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as figure 1 , image 3 and Figure 5 As shown, it is the first embodiment of the electrical connector 100 of the present invention. The electrical connector 100 of the present invention is an electrical connector 100 for electrically connecting a chip module 8 to a circuit board 9, which includes a body 1 The body 1 is provided with a plurality of receiving holes 13 arranged in multiple rows and columns, and a plurality of terminals 3 are respectively inserted into the receiving holes 13 from bottom to top, and one end of the terminals 3 elastically abuts against the chip module 8. The other end is soldered to the circuit board 9 through a solder ball 4, and a metal layer 2 is plated on the insulating body 1.

Abstract

The invention discloses an electrical connector for electrically connecting a chip module, comprising: a body with a plurality of receiving holes, the body has an upper surface; at least one protrusion protrudes upward from the On the upper surface, an insulating part is located on the raised part for supporting the chip module; a metal layer, the metal layer covers the upper surface and around the raised part; a plurality of terminals are accommodated in the receiving hole, used to connect the chip module; the metal layer covers the upper surface and the surrounding of the convex part, and the insulating part is located on the convex part to support the chip module, which ensures that the metal The layer better shields the crosstalk between the terminals, satisfies the transmission of high-frequency signals of the terminals, and prevents the metal layer from contacting the chip module, preventing the chip module from short circuiting.

Description

technical field [0001] The invention relates to an electrical connector and a manufacturing method thereof, in particular to an electrical connector with a shielding effect and a manufacturing method thereof. Background technique [0002] With the rapid development of computer technology, the number of terminals of LGA electrical connectors is increasing, which causes the terminals to be arranged very closely, making it easy to generate signal interference between terminals. In order to shield the signal interference between terminals, a commonly used in the industry The electrical connector is used to electrically connect a chip module to a circuit board. It includes a body on which a plurality of bumps are integrally formed to support the chip module. The body is provided with a plurality of signal receiving slots and A plurality of grounding storage slots, a plurality of signal terminals and a plurality of grounding terminals are respectively stored in the signal storage ...
