Abstract

The invention provides a flow guide bonding pad. The flow guide bonding pad comprises a first bonding pad and a second bonding pad, wherein the first bonding pad is located between a nickel sheet anda PCB, and at least one opening penetrating through the first bonding pad is formed in the first bonding pad; the second bonding pad is positioned in the opening; a via hole is formed in the center area of the second bonding pad, at least one flow guide structure is arranged on the surface, which is adjacent to the PCB, of the second bonding pad, and one end of each flow guide structure is communicated with the outer diameter of the via hole. According to the flow guide bonding pad, the welding stability and flatness between the nickel sheet and the PCB are improved.

Description

technical field [0001] The present invention relates to the technical field of battery management system welding, and more specifically, to a current-conducting pad. Background technique [0002] With the increasing use of electric vehicles and the continuous improvement of battery capacity, the number of battery cells is also increasing, resulting in a rapid increase in the collection of battery cells. [0003] In order to reduce the usage of the collection harness and improve the reliability of the battery cell collection, a technology that replaces the wiring harness by directly collecting the voltage of the battery cell through the nickel sheet on the PCB has emerged as the times require. [0004] However, at present, the soldering stability between the nickel sheet and the PCB board is poor. Contents of the invention [0005] In view of this, in order to solve the above problems, the present invention provides a conduction pad, the technical solution is as follows: ...
