Since the emergence of new energy vehicles, the demand for charging piles has been increasing day by day. Many manufacturers or merchants are preparing to install or produce charging piles to obtain new energy-wave business opportunities. Many merchants have begun to pay attention to their charging piles. The circuit boards used in charging piles It has also become their first target.
The charging pile circuit board is generally a thick copper circuit board with more than four layers, and the copper thickness is usually above 1.6. The main reason is that the charging pile circuit board has a large current and high voltage, and the thin board cannot bear it. Although the materials are all made of copper, there are also certain differences in grades. The ordinary board material is below ordinary TG140, the charging pile circuit board material is generally above medium TG150, and the high TG is 170. The data is the parameter of the grade, the higher the grade, the better the temperature resistance effect and the higher the quality of the plate.
However, the circuit board itself requires high current and high voltage, so it is very important to design a standard circuit board for charging and discharging tests for the battery. Not only the charging pile but also the voltage required by the car must be considered. Unreasonable design may cause the circuit board to burn out.
Charging piles belong to the supporting type of automobile peripheral products, which do not allow problems such as line defects, or residual copper on the side of the line, solder resistance on the side of the hole, etc. Some customers implement the IPC-Ⅲl level standard to implement the zero-defect acceptance specification, which is much stricter than general consumer PCB boards.
Although the charging pile is a popular industry, the competition is also fierce. The review of the charging pile is also extremely strict. Therefore, in the production process of the core accessories of the charging pile, it is necessary to find a powerful circuit board manufacturer, such as circuit boards. The core components that carry the operation of the entire system, so its importance can be imagined, and the quality of the charging pile circuit board must be strictly checked.
