    Which layout the best?

    I not see great advantage with second image. You can add a copper shield, (blue color) but this cannot make a great advantage. The RED plane are the most important, reference (GND) and EMI shield plane. Skywalker.

    PADS LAYOUT : How to remove component w/o unroute ?

    Hi, the best practice is to use a new netlist with changes, in ECO mode. Otherwise you can delete a old part then you add a new. But in this case you delete and add connections manually, not recommended for complicate board. If you edit a decal in pcb layout, you cannot delete a pin and cannot...

    Issues when transferring from 4 layers microstrip PCB to 2 layers RF PCB

    Re: 2 layer RF PCB Another important consideration. The impedance of micro-strip lines, is not the same if the dielectric thickness change. IF strip-lines are used in the four layer, this may result in a big problem into 2 layer board. Skywalker.
