Pcb prepreg thickness

SpletAn IMS PCB can be designed with a very low thermal resistance. If, for example, you compare a 1.60 mm FR4 PCB to an IMS PCB with a 0.15 mm thermal prepreg, you may well find the thermal resistance is more than 100 times that of the FR4 PCB. In standard FR4 products, it is very difficult to dissipate a large amount of heat away from components. SpletIf we took one ounce of copper and rolled it flat to the point where it covered one square foot, then the copper would end up being 0.0014 inches thick. That is one-ounce copper. Copper weights can be less or more so we can work in fractions of an ounce or multiple ounces for higher current capacity.
