What are the factors to keep in mind while designing a silkscreen for your PCB? Manual Screen Printing is one of the easiest methods to create a Silkscreen layer that supports all types of texts. The next step involves the curing of ink in the baking oven.Then, the stencil on the layer or laminate directs the ink accordingly. The process would involve converting the traces to nylon.Manual Screen Printing: You can opt for Manual Screen Printing when the tolerance level of registration equals 0.005″ or the line width exceeds 0.007.” One would perform Manual Screen Printing with the help of stencils that comprises texts & traces.However, you can mainly use DLP for processing the PCB assembly steps, referring to mounting the components. The users do the PCB Silk Screen Printing at the time of fabrication. The ultra-violet light cures the printed ink. In this technique, people would extensively use acrylic ink, applied directly on a raw PCB via CAD data. Direct Legend Printing – If you seek a better quality irrespective of the cost, Direct Legend Printing would be the right choice.The LPI gives you a better quality of screening & higher resolution of images and texts through it consumes more time & ink than Direct Legend Printing & Manual Printing. The liquid photo-imageable epoxy would cover the lamination & get exposed to ultra-violet light after the development of the Silk Screen Circuit Board gets complete. It has some of the shared similarities with the process followed for the solder mask’s application. Liquid Photo Imaging – You can use Liquid Photo Imaging when the line widths exceed four mils.The Silkscreen PCB printing offers you some of the Silk Screen printing methods. What are the methods of silk screen printing? Part Numbers: It helps you to get the device information in the absence of a datasheet.Test points: It helps indicate the board’s location with known values, which would be helpful when you identify the problems with board operations.The PCB Silkscreen also assists the engineers, technicians, and the manufacturers with the locations where you would need to take measurements at the time of testing and troubleshooting process that include: But you can’t miss out on indicators, Pin 1, Polarity indicators. However, you would need them for general placement. The Component Online wouldn’t be essential for simpler components having a smaller number of pads.
