#106276 - Depends
Responding to: ???'s previous message

But i did it upside down compared to what andy said. I put my drawn PCB traces on the bottom and the ground plane at the top.

Which methode is better depends a bit on what connectors are to be soldered and on what side of PCB you want to solder them.

In earlier days, I always mounted the chips on sockets. But in those days achievable sockets were more expensive than the chips. And, I had lots of contact problems, because they hadn't gold contacts. Funny enough, I never had a damaged chip to exchange, which finally is the reason to use sockets at all, isn't it? So, one fine day I neglected all these shitty sockets.

Anyway, when using SMDs there isn't any socket on board, is it?
