Subject: Re: [Homebrew_PCBs] Good techniques for cleaning up old artwork?

Wire Wrap sockets will allow you go get about as far above the board as you want and solder the pins on top as well.  I am not sure you can find some of the newer size sockets like the 24 and 28 pin .3inch spacing between rows types or even the 18 and 20 pin but they probably exist.

In the 70's I bought some strips of ic pins.  You broke off the number you needed per row and stuck them in the holes and soldered them (top and bottom if you wanted as there was no plastic carrier for them) and then broke off the metal flange to separate the pins.  I can't remember what they were called but they were used and sold in the Hal ST6 rtty converter kits I built.

Also you can probably use a regular socket and solder all the pins on the bottom them pull the plastic carrier up and off the pins to do the top then MAYBE you can get that plastic carrier to go back over the pins.

Good luck.

It used to be possible to get IC sockets that were solderable from both sides. The socket pins came up over the side of the socket, making it (relatively) easy to reach them with a small iron. It's still possible to find sockets that have long enough pins to be solderable from both sides if they're not mounted flush with the board.
