PCB Silkscreen Easter Eggs

Hidden messages or easter eggs on circuit boards, often referred to as “silkscreen easter eggs,” are fun and deliberately secretive messages hidden on the silkscreen layer of printed circuit boards (PCBs). The silkscreen layer is the topmost layer of a PCB, typically used for labeling components, indicators, providing assembly instructions, or other information. Normally these are lighthearted messages. The creative origin of these easter eggs could be from anyone involved within the manufacturing chain: engineers, designers, or even directly from the manufacturers.
