Using these IC sockets is easy. First, if you're working on a Perma Proto or PCB, solder the socket onto it. Then, you can simply insert your 40 - pin chips with 0.6 - inch pin spacing into the socket. When you need to replace a chip, just gently remove it. Remember, these sockets aren't for solderless breadboards because the pins are too short. For maintenance, keep the sockets clean and free from dust. If you notice any loose pins after soldering, you can carefully re - solder them to ensure a good connection.
