Question:
A customer asked: "Is Pin 1 on the left side of the IC chip?"
Answer:
When identifying Pin 1 on an IC (integrated circuit) chip, there is always a small dot or indentation on the chip that marks Pin 1. This marking is a universal standard used in the electronics industry. Pin 1 is the starting point for the pin numbering sequence, which is critical for proper orientation when connecting, soldering, or programming the IC.
If you position the IC chip with the dot or indentation at the top-left corner, Pin 1 will be directly below the dot. The pin numbering then follows a counter-clockwise direction around the chip. For example, if Pin 1 is on the top-left, Pin 2 will be immediately to its right, and the numbers will continue counter-clockwise around the chip’s perimeter. Understanding this orientation ensures that the IC is installed correctly and avoids damage caused by improper connections.
