Built up a pcb.
Tried to insert op amp and op amp legs 1 and 2 bent.
Straightened legs and tried again but op amp wouldnt go into DIL socket.
So tried putting a thin wire into pin 1 and it wouldnt go in.
Some sort of blockage on pin 1 and pin 2.
So had to desolder DIL socket and replace it.
Never had that problem before and they were RS sockets so not cheapest.

It looks like the faulty pins havent been formed right and are blocking the hole.
I have replaced it now and its now OK.

I’ve had solder wick up into IC sockets before. Tube sockets, too. At least with ceramic tube sockets you can remove them, heat the offending pin with an X-rated iron and give it a good shake to remove the solder. IC sockets are expendable.
The gap between pin and plastic housing is minimal so shouldnt leak solder.
I have been in electronics 43 years and its the first time i had a bad new socket.
Yes the sockets are pennies just a pain having to remove the bad one.
It isn't the space between pin and plastic, the pin itself if you run too much solder into it, can wick up in between the contact surfaces and solder them together. Milled sockets won't do this of course, but other basic sockets can.
Just use the better milled IC sockets and relax. When cheap IC sockets are used one is sometimes better off not using sockets at all.

I never use IC sockets, they are less reliable than the ICs that go in them. A DIP IC is so easy to remove, why bother?
