SpletThere is an extensive range of thickness of PCB that can be accomplished through combination of various sheet prepreg and core thicknesses. At RayPCB we are offering … 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.
