What is PCB Silkscreen? Why is PCB Silkscreen so important?

Within the realm of PCB manufacturing processes, there exists a pivotal technique known as silkscreening. Today, we delve into the topic concerning PCB silkscreen—an essential aspect of the production process. Let's explore the?significance associated with PCB silkscreening.

1. What is Silkscreen?

Silkscreen is typically employed on PCBs to convey useful information, aiding users during assembly by marking component values, part numbers, polarity, and more. It also includes details such as versioning and manufacturer information. Silkscreen can consist of letters, numbers, and text.

PCB silkscreen is accomplished during the PCB manufacturing process but is utilized in the assembly phase of PCBs.

The image below illustrates an example of silkscreen on a finished PCB.
