Although PCB silkscreen printing is an automated process, the following are a few factors to be addressed during the process.
Font Type: Earlier, only a few standard fonts were allowed by CAD software, but now various fonts are used for silkscreen printing. The silkscreen contains important information on which engineers rely. Ensure to choose a font that is clearly readable by everyone.
Font Color: PCB silkscreen printing is done in different colors such as white, yellow, red, blue, and so on. Choose a silkscreen color that clearly gets highlighted on your printed circuit boards. For instance, if a PCB is green, white silkscreen printing can be a good option.
Designation: The location of the components and connections should be printed as close as possible to avoid any miscommunication. If the component density is high, silkscreen could be printed inside the elements with precise arrows and directions.
Reading Directions: The reading directions should be clear and simple, starting from left to right and bottom to top. This will make the circuit board more comprehensive for the engineers.
