In the rapidly advancing field of new energy electric vehicles (EVs), the demand for high-performance and reliable printed circuit boards (PCBs) for inductor coils is soaring. Our 20-layer Inductor Coil PCBs are specifically designed to meet the rigorous requirements of high - voltage applications in EVs.
Constructed using TU865 material, these PCBs offer excellent electrical insulation and thermal stability, which are crucial for handling the high voltages and currents encountered in EV power systems. The board thickness of 4.0mm and a thickness ratio of 8:1 ensure sufficient mechanical strength to withstand vibrations and shocks during vehicle operation.
One of the standout features of our PCBs is the use of 3oz copper. This thick copper layer provides low resistance, enabling efficient power transmission and reducing energy losses. The double - pressed manufacturing process further enhances the copper layer's adhesion to the substrate, ensuring long - term reliability under high - stress conditions.
The POFV (Plugged Over Via Full) technology is another key advantage. By filling the vias, it prevents the ingress of moisture and contaminants, reducing the risk of electrical shorts and improving the overall reliability of the PCB. Additionally, the minimum aperture of 0.5mm and minimum trace width/spacing of 180/180μm allow for precise circuit layouts and high - density component placement.
The lead - free spray tin (HASL - Hot Air Solder Leveling, lead - free) surface treatment provides excellent solderability while being environmentally friendly, ensuring reliable component attachment during assembly.
