Let's Break Down the Description:

14/16/18/28/40 Pin: The socket is available in various pin configurations, including 14, 16, 18, 28, and 40 pins. This indicates the number of pins the socket can accommodate, providing flexibility for different IC sizes.

2.54mm Pitch: The pitch of 2.54mm refers to the distance between the center of one pin to the center of the adjacent pin. This is a standard pitch commonly used in electronic components and connectors.

Green DIP Universal ZIF IC Lock Socket: "Green DIP" suggests that the socket has a green-colored housing and is designed for Dual In-Line Packages (DIP). "Universal ZIF IC Lock" indicates that it is a Zero Insertion Force (ZIF) socket, meaning that it allows for easy insertion and removal of ICs without applying significant force. The term "Universal" implies that it can accommodate different IC sizes within the specified pin range.

Test Solder Type: The socket is designed for testing purposes, allowing you to easily insert and remove ICs for testing or programming without soldering directly to the IC.

Solder Type: This indicates that the socket is intended to be soldered onto a printed circuit board (PCB). It is not a socket designed for use in socketed IC bases but rather for direct soldering onto a PCB.
