Understanding Silk Screen Technology in Printed Circuit Board (PCB)

Adding the silkscreen layer onto a printed circuit board is the final step in the fabrication process. Silkscreen is a layer that uses ink traces to identify all the PCB board components, test points, parts of the PCB, warning symbols, logos and marks etc. These shapes, numbers, and letters really aren’t some new language. They can also communicate the function of each of the pins. This silkscreen is applied on the component side; all though you may find the use of silkscreen on the solder side is also not uncommon, which will increase the cost. Essentially a detailed PCB silkscreen will benefit both the manufacturer and the engineer to locate and identify all the components.
