[QUOTE="John Roberts, post: 116185, member: 126"] Re: New QSC Product - TouchMix At Peavey we used millions and millions of sockets where the ICs were machine inserted into the sockets by the same machine that inserted the socket into the PCB. I don't recall if they were Amp or Molex but a good quality brand name socket. I do not recall any failures because of the sockets. In manufacturing, you don't want humans touching ICs, machines cause less mischief from static and whatever. In theory a metal to metal connection in a socket may seem suspect for degradation from oxidation or contamination, but when properly executed the socket connections are robust and reliable. With modern IC reliability there is far less reason to ever use sockets. Back when I was starting out, decades ago even new ICs did not always work... For my kit business back in the '70s I used to test new IC's 100%, before re-selling them, and in the early days I weeded out a small fraction of weak sisters or duds. JR [/QUOTE]
