1. Silicone RTV. I used it for years on socketed EPROM's in a portable instrument. Occasionally they needed updates when in the shop for repairs and I never saw the slightest corrosion from the RTV. However, I never applied the RTV to the pins. A tiny dab at each end of the chip to the socket was sufficient. 2. Nylon penny ties (cable ties, ny-ties, etc.) could be used if they fit under the socket or through pcb holes if there are any suitable. 3. PIC12F508 w/ICSP. No socket.
