In the automotive industry, where reliable and high - performance power distribution is vital for the proper functioning of various electrical systems, our 18 - layer Thick Copper Secondary Power PCBs stand out as an ideal solution.
These PCBs are constructed using IT180A material, which offers excellent thermal conductivity and electrical insulation properties. This is crucial in automotive applications where the PCBs are exposed to varying temperatures and high - voltage electrical signals. The board thickness of 3.8mm and a thickness ratio of 11:1 provide the necessary mechanical strength to withstand the vibrations and shocks that are common in a moving vehicle, ensuring long - term durability.
One of the most significant features of our PCBs is the use of 4oz copper. The thick copper layer enables efficient power transmission with minimal resistance, reducing energy losses and heat generation. This is especially important in automotive power systems where high currents are involved. The double - pressed manufacturing process further enhances the copper - to - substrate adhesion, preventing delamination and ensuring reliable performance under extreme conditions.
The POFV (Plugged Over Via Full) technology is another key advantage. By filling the vias, it prevents the entry of moisture and contaminants, which could otherwise lead to electrical shorts and component failures. The minimum aperture of 0.35mm and minimum trace width/spacing of 180/200μm allow for precise circuit layouts and high - density component placement, optimizing the use of available space on the PCB.
The Immersion Gold (ENIG) surface treatment provides excellent corrosion resistance and solderability, ensuring reliable component attachment during the assembly process. This is essential for maintaining the integrity of the power system over the lifespan of the vehicle.
