It's not cheap, but here's a product I highly recommend for contact problems: http://www.posthorn.com/Stab_2.html In more years than I want to remember I've never had to replace a socket unless it was damaged in some way. When I was selling and supporting custom systems running in a very hostile industrial environment I would have an IC-socket related service call every few weeks, which stopped completely after treatment. The only issue I have observed in my 2001 series PETs is that with any handling (flexing) of the board a chip will occasionally tend to creep out of its socket. Probably not economic for a single application, but I thought I'd mention it anyway. m ----- Original Message ----- From: "Francesco Messineo" <email@example.com> To: <firstname.lastname@example.org> Sent: Monday, February 06, 2017 12:55 PM Subject: Re: UD3 ROM on a 3032 > On Mon, Feb 6, 2017 at 6:51 PM, Christian Dirks <Toast_r@idealine.info> wrote: >> Am 06.02.2017 um 08:23 schrieb Francesco Messineo: >>> Changing all the 40 pins one will be a long job anyway :( >> >> If you have the usual white sockets, it can be done very easy. >> The white plastic carrier can be lifted off with a screwdriver, leaving >> the solderd pins in the PCB. >> After that, the pins can be desoldered one by one. > > sure, I noticed that.
