Problems solved by technology

[0004] The copper substrate protected by the BMS of the new energy electric vehicle is the core component of the entire battery management system. At present, the production of the copper substrate adopts the conventional PCB manufacturing process, which discharges the copper into the FR4 substrate and presses it. Direct pressing will cause deviation movement Phenomena, it is difficult to guarantee the accuracy

specific Embodiment approach

[0039] The specific implementation method of the present invention is as follows: the double-sided copper-clad FR4 substrate is made into a core board, and copper bars are embedded in the corresponding slots on the core board, and then PP is pasted on the upper and lower surfaces of the core board (PP is 2116RC55%, thickness 0.129mm), and then attach a FR4 single-sided board with one side free of copper and one side copper-clad on the PP, and make one side of the bare board contact with PP, and then stick a release film and a silicone board on the copper-clad side of the FR4 single-sided board , and then use the above-mentioned HT-G001 pressing program for pressing.

[0040] In summary, the present invention solves the problem that the existing PCB process cannot produce the BMS protective copper substrate of new energy electric vehicles. It presses the BMS protective copper substrate by pasting high-temperature tape and adjusting the parameters of the pressing program. As a r...

Abstract

The invention provides a manufacturing method of a copper substrate for new energy electric vehicle BMS protection. The manufacturing method includes: manufacturing a copper bar; manufacturing a FR4 plate; manufacturing the copper substrate. The manufacturing method has the advantages that the copper substrate lamination technology is used to perform lamination on the BMS protection copper substrate by adhering high-temperature tape and regulating lamination program parameters, deviation movement during lamination is avoided, and precision is guaranteed; the problem that the BMS protection copper substrate cannot be produced by a traditional process is solved, and product quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of printed circuit board manufacturing, and specifically relates to a method for manufacturing a copper substrate used for BMS protection of new energy electric vehicles. Background technique [0002] The battery management system (BATTERY MANAGEMENT SYSTEM, BMS) is an important link connecting the vehicle power battery and electric vehicles. Its main functions include: real-time monitoring of battery physical parameters; battery state estimation; online diagnosis and early warning; charging, discharging and pre-charging control and Equilibrium management and thermal management, etc. As an electronic component for real-time monitoring, automatic balancing, and intelligent charging and discharging, BMS plays important functions such as ensuring safety, prolonging life, and estimating remaining power. It is an indispensable and important component in power and energy storage battery packs. [0003] Electric v...
