Circuit board and energy transmission equipment

Abstract

The invention provides a circuit board and energy transmission equipment. The circuit board comprises a substrate and a wiring layer arranged on the substrate, and the wiring layer is provided with a circuit, a first bonding pad and a second bonding pad. The first bonding pad and the second bonding pad are used for being connected with two PINs of a capacitor in a one-to-one correspondence mode. When the circuit is connected, at least one of the first bonding pad and the second bonding pad is electrically connected with the circuit through a wire, and the wire serves as a fuse for protecting the circuit. According to the technical scheme, the mode that the bonding pad connected with the capacitor is directly connected with the circuit is not adopted, the circuit is connected with the bonding pad through the wire, the wire can be fused when the capacitor is broken down, the function of a fuse is achieved, the risk that the whole circuit is affected when the capacitor is broken down is reduced, the safety of the whole circuit board is improved, and the safety of equipment using the circuit board is also improved.

Description

technical field [0001] The present application relates to the technical field of circuit boards, in particular to a circuit board and energy transmission equipment. Background technique [0002] Electrolytic capacitors are common energy storage devices on circuit boards and play an important role in power lines. Generally, circuit boards with output rectification will have this device. The existing series-parallel layout technology of multiple electrolytic capacitors is directly connected to the PCB, which only considers welding or current sharing, and does not consider the risk of arcing in the event of failure. [0003] Since the electrolytic capacitor itself stores a lot of energy, especially in the case of high-voltage multiple series-parallel connections, once the electrolytic capacitor fails, it will often be accompanied by arcing. Once the device fails, it will often have a great impact on the entire equipment. In this case, the entire device will burn down. Conten...
