    Bad opportunity to generalize.

    In an impedance matching network built using passive parts, I guarantee you will have to unsolder and try different values of parts until you get a usable RF match.

     If you don't put thermal relief on the ground vias or even the outer layer SMT pads, you will only get about two part swaps in and out before you caused the pad to lift from the board.
