PCB production

[vick5821]

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

ya..trace width can be increase for high current..why? And how to deal with sensitivity to noise?

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

And how to deal with sensitivity to noise?

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 ?

Um, the same way a bigger wire does...
