Claim 25:
26. A hybrid power switch module, comprising:
a first printed circuit board (PCB) having a first and a second sides,
a second PCB having a third and a fourth sides, said second PCB being secured to said first PCB with said second and fourth sides thereof facing each other,
a first plurality of switch dies and a second plurality of switch dies having a respective predetermined topology on a respective one of said first and third sides of said first and second PCBs, respectively, wherein at least one first switch die of said first plurality thereof and at least one second switch die of said second plurality thereof are disposed in a double-sided fashion on said first and third sides, respectively, of said first and second PCBs, wherein each of first and second pluralities of said switch dies includes a gate terminal and a source terminal facing a respective one of said first and third sides of said first and second PCBs, respectively,
a plurality of spring pins, each soldered in a respective through-hole via (THV) formed through each of said first and second PCBs in alignment with said gate terminal of each switch die, each of said plurality of spring pins having a first cap at one end thereof in electrical contact with said gate terminal and a second cap at another end of said each spring pin exposed from said respective THV and secured to a respective one of said second and fourth sides of said first and second PCBs, respectively, and
a plurality of multi-functional components (MFCs), each expanded vertically from a respective one of said first and third sides of the first and second PCBs, respectively, and secured to said first and second pluralities of the switch dies through an elastic metal contact.
