does not need heat sinking, as chassis of structure shall heat sink the voltage regulators or transistors or other high power components to itself through

must have through holes for 4-40 screws for mounting onto a superstructure

1/2 inch thick otherwise)


dimensions of pcb allowed:
18 inches long (desire 12 inches max but can go up to 18)
3 inches wide (desire 2 inche...
