  4. good job my friend, keep going.
    i think ... is it better if you sell the pcb..
    and we just buy it from you.

    best regard's

    1. "Heat Sink" it is used to keep cool Integrated Circuit in a manner. It is basically a Aluminium alloy. and there don't need any circuit in that perspective. Just attest at lest a minimum size aluminum allow. For that you have to know that how to determine perfect size Heat Sink.
