Homebrew PCBs

Thanks a lot everyone for ur suggestions...i really appreciate 
it...i looked around for sockets, but i find them to b really 
expensive and probably my prof wont allow me to use them for labs. 
this is wat i did - > i silvered the copper pads first to prevent 
further oxidation and to give a cleaner surface. then i placed the 
transistor on the pads and put a tape on it to hold it to the PC 
board. and checked in the network analyzer. i was seeing lotta 
resonance points. so, i went ahead and tried to put some more 
pressure on the transistor to hold it firmly to the pads. then i 
could c no resonance points. So for now i'm using a clip arrangement 
to exert pressure and that kinda works fine. its wooden clip and so 
it isnt affecting my calculations. its not a permanent solution, but 
hey it was an easy solution. any comments abt this ??
