Parallel-welded printed circuit board connector

Abstract

The invention discloses a parallel-welded printed circuit board connector. The parallel-welded printed circuit board connector comprises a plug and a socket, wherein the plug is composed of a plug shell and a jack closing component; the socket is composed of a socket shell and a pin closing component; the parallel-welded printed circuit board connector is characterized in that a plurality of equally high supporting lug bosses are arranged on both the plug shell and the socket shell, sunken flared openings are formed in both the jack closing component and the pin closing component, solder balls are arranged in the flared openings, and the jack closing component and the pin closing component are arranged in the receiving grooves of the plug shell and the socket shell, respectively. According to the parallel-welded printed circuit board connector, due to the structure comprising the supporting lug bosses arranged on the shells and the flared openings in the terminals, the depth of parallelism between the BGA connector and the printed circuit board before and after welding is guaranteed and the solder balls are kept at the positions of the axel of the terminals, and therefore, the product percent of pass is greatly increased.

Printed circuit board technology is one of the main circuits that carry various components in electronic equipment. The printed circuit board connector in the prior art, that is, the BGA connector, is an electrical connector that realizes the interconnection of printed circuit boards between electronic devices. The connector has the advantages of occupying a small area of ​​the circuit board, many contact points, and high arrangement density. For this reason, the BGA connector has become the main connection mode of the printed circuit board connection; It is characterized by small spacing, many terminals, and each terminal contains solder balls. When the BGA connector is soldered to the printed circuit board, the solder balls on all terminals must be in contact with the corresponding solder points on the printed circuit board at the same time. , no matter before or after soldering, the BGA connector and the printed circuit board need to maintain a high degree of parallelism. The existing problems are, first, it is difficult to ensure that the solder balls on each terminal and the axis of the terminal are in reality There is no deviation, so that the solder balls cannot be in one-to-one contact with the solder joints of the printed circuit board; second, when the solder balls of multiple terminals on the BGA connector are soldered to the solder joints of the printed circuit board, when the solder balls dissolve In an instant, the parallelism between the BGA connector and the printed circuit board is difficult to guarantee, resulting in false soldering between terminals and solder joints, weak soldering or short circuits between adjacent pads, which seriously restricts the product qualification rate. improve
