Plasma cleaning removes organic contaminants from the surface of the solder pads before soldering, which enhances the wettability of the solder to the pads and reduces soldering defects caused by contamination.
As the nerve center of an automotive electrical system, the rationality of its layout directly affects the safety, reliability, and assembly efficiency of the entire vehicle.
In terms of structural design, industrial control wiring harnesses should adopt a reasonable layout and layered design to reduce mutual interference between conductors.
For high-voltage wiring harnesses in new energy vehicles, withstand voltage tests and insulation resistance tests are also required to ensure that the solder joints can maintain a stable connection under high-voltage conditions.
During system design, matching terminating resistors should be connected at both ends of the bus according to the requirements of the bus protocol to ensure the stability of signal transmission.
In the complex architecture of modern automobiles—especially intelligent electric vehicles—wiring harnesses are like "neural networks," connecting hundreds of electronic control units, from battery management systems and autonomous driving sensors to cock
