    As an engineer , you are needed to design a PCB for your company's product.The product should handle a larg amount of current and very sensitive to noise. Explain two criteria for you to consider before building your PCB.

    Any ideas guys ? Please help

    Thank you

    Is there anything that you can suggest might help? Perhaps if you miss something or don't quite get it right we can set you straight.

    There are lots of things to consider, trace width, trace thickness, routing, application, product environment, possibly using internal (or external) layer ground planes for shielding, what parts or areas might be shielded blah blah blah

    Are you making a trace that handles the load or a fuse? Both trace width and trace thickness will make that difference...

    I tossed up several options to consider, there are of course others...

    This is a type of exam question.Btw, just to ask, how does increase in the net thcikeness/width can sustain more current ?
