Hello Everybody,

Does anyone here on the forum know if there are any advantages of using gold plated IC Sockets over tin plated IC sockets for soldering into a through-hole technology circuit board to justify the extra cost (2X) of the gold plated sockets?

I am rebuilding a vintage keyer with an updated circuit board and do not know if I should purchased gold plated or tin plated IC sockets.

Regarding the IC sockets, I am referring to the pins of the socket that are soldered into the circuit board.

Thank You for your assistance and 73's

Gold doesn't rust or oxidize. As a keyer uses very low currents that won't burn through an oxidation layer, I use gold plated sockets or just solder in the parts.

If cost is an issue, I would not hesitate to use tin plated sockets. If, a few years down the road, you suspect that you may have developed a poor contact, it's easy enough to re-seat the IC in the socket, and you should be good for another few years.
