Using these IC sockets is easy. First, make sure you have a suitable PCB or protoboard for soldering. Then, carefully place the socket on the board where you want the chip to go. Solder the socket firmly to the board. When you need to insert a chip, just align the pins of the chip with the holes in the socket and gently press it in. To remove the chip, use a small tool to carefully lift it out. Here are some important notes. These sockets are only for 28-pin chips with 0.3-inch pin spacing, so don't try to use them with other types of chips. They're not suitable for solderless breadboards because the pins are too short. For maintenance, keep the sockets clean and dry. If there's any dust or debris, you can use a soft brush to gently clean them. And that's all you need to know to make the most of these handy IC sockets!
