What is silkscreening on a printed circuit board

Silkscreening is printed symbols, letters, numbers, inscriptions on a printed circuit board.

For example, PCB name, logo, polarity of parts, location of test points and other data about the circuit and its components. Silkscreened test points facilitate debugging and repair. They enable service technicians to quickly identify components and efficiently troubleshoot problems.

The silkscreen is usually applied on top of other layers of the PCB and used as a reference. The process of creating a silkscreen on a printed circuit board seems simple, but it requires careful attention to the size, placement, color, and contrast of the text. As technology advances, the PCB silkscreening process continues to evolve, offering more and more precision and capabilities.

Understanding the intricacies of printed circuit board silkscreening is essential for anyone involved in the design, manufacture or use of printed circuit boards. The inks used for silkscreening are non-conductive epoxy inks in a variety of colors including black, white, red, blue and yellow.
