#PCB Manufacturing
In the design of a power electronic PCB, I want to use a metal PCB for heat dissipation of a TO-220 package MOSFET. To do that I want to mount metal PCB on the MOSFET with the use of thermal paste and screw exactly like we do when we use heatsink for the same package. Should I leave the copper of PCB between MOSFET surface and dielectric of PCB or remove the copper surface and leave only the dielectric opening?
I required a BOM from PCB designer of manufacturer, but he sent me a Gerber. How can I open and read it?
