Abstract

The embodiment of the invention provides a golden finger and a plate edge interconnection device. The golden finger comprises a PCB surface layer and at least one PCB inner layer, wherein the metallic foils of the PCB inner layer are communicated with the metallic foil on the PCB surface layer through a through flow structure; and the through flow channel of the golden finger comprises the PCB surface layer and the PCB inner layers. The plate edge interconnection device comprises the golden finger. According to the embodiment of the invention, under the premise that the size and thickness of the copper foil in the PCB in the golden finger are not increased, and the through flow channel of the PCB in the golden finger is increased, with greatly improved through flow ability.

Description

technical field [0001] The invention relates to communication technology, in particular to a gold finger and board edge interconnection device. Background technique [0002] With the continuous improvement of the power density of power products, the current flowing in the products gradually increases. It can be seen that power products are developing in the direction of miniaturization, high power and high current. Golden Finger refers to the gold plating on the copper foil on the surface of the printed circuit board (Printed Circuit Board; hereinafter referred to as: PCB) to enhance its wear resistance and improve reliability; The reeds of the connector make contact, which can realize the transmission of signals or energy. It can be seen that the use of the gold finger and the gold finger connector can effectively save the product space and improve the power density of the product. Gold fingers have been widely used in traditional electronic products, such as conductive c...
