The 2-layer PCB stackup can be clearly demarcated. Layer 1, or the top layer, is described as a signal layer. The 0.0014-in.-thick layer is made of copper material; the copper amounts to about 1 oz.

A step-down PCB is simply a multilayer PCB whose board thickness is reduced (stepped down) in a few places. The step-down is ...

My 2 layers PCB designs typically has around 65% area filled by single sided components. I got one populated on both sides at around 70%. I might be able to squeeze another 10%, ...

But as you can see above, there are additional choices when it comes to multi-layer boards. #1 is a through via connecting all of the layers. #2 is a blind via; it stops part way through the board.

Compared to a 4-layer PCB, a 2-layer PCB layout has higher parasitic inductances within the hot loop, which increases the resonance amplitude and changes the location of the switch-node resonance. The ...
