Andy,I could do that but I want to seperate the SMD TQFP from other Non SMD components and conceal the this Socket with Epoxy .

Bruce,I know how to connect the Grounds But my question is can we connect the Grounds from a PCB on top of a PCB .
I have seen the architecture of BASIC STAMP and it also shows
SMD aggregrate on a small PCB(called basic stamp) which is to be mounted on the final mother board .I want to know that if the two seperate grounds are on the SMD aggregrate chip DGND and AGND and two on the motherboard AGND and DGND .Then can we connect the these two via pin connectors on the mother board OR do we have keep them seperate ,the AGND and DGND of Adaptor seperate and joined on Adaptor and the motherboard AGND and DGND seperate .
