Yeading celebrate reaching the FA Cup 3rd round
Slough had taken the lead when Glen Harris scored from the spot after Nevin Saroya upended Alex Haddow.
But Campbell bundled the ball home in a goalmouth scramble and added a second after the break when he headed in Davis Haule's cross from 12 yards.
Another header, this time from Haule, gave Yeading their third goal and a deserved victory over Slough.
