1/27/2024 0 Comments Silkscreen pcbWhether it is to do with font sizes or line widths, do stick to the specifications. To avoid these common errors, the design guidelines must be followed carefully. Split Silkscreen InkĮver so often the silkscreen ink can cover the surface mount pins and can cause damage to the board. The other issue with reference designators often has to do with dense designs, where reference designators are hidden by assembled components. In testing the board, technicians then have to grapple with the issue of the schematic not matching the board. Wrongly Placed Reference DesignatorsĪnother common mistake that leads to error and a lot of angst among technicians, is to do with erroneously placed reference designators. Using a very small font size or too narrow or too wide a line width are all potential causes of unreadability. non-ReadabilityĪnother commonly faced issue is to do with the legibility of the silkscreen text. Components not represented correctlyĪny small error in the silkscreen and its intended components, their shape, location, polarity indicators, etc can lead to a whole lot of issues for the technicians when they are doing any modification or a debug. While the importance of Silkscreen is undisputed, what also comes in its wake are several potential issues, which if not taken care of can lead to costly errors. It is also faster than LPI, even though it comes at a higher cost. In terms of accuracy, this method is rated the highest. In terms of accuracy, this turns out to be more accurate than manual printing, even though the approach is time intensive. This is used when the line width is more than 4mil. From the accuracy point of view, however, this isn’t the most desirable choice as the output is determined by aspects such as the viscosity of the ink, humidity, pressure of the stroke, and more. This is typically used when the line width is greater than 7mil and registration tolerance is 5 mil. YOU MAY ALSO LIKE: What Are Gerber Files In PCB? 3 Types of Silk Screen Printing Technology 1.

What Is Silkscreen In PCB?Īn effective silkscreen is a layer of ink trace that acts as an efficient map with the right calibrations and information of various essential components such as logos, symbols, PCB components, marks, test points, etc. Not only does it contain valuable information about the location of components, but it also contains other indispensable information such as identifiers, labels, and more. When it comes to PCB Manufacturing, the importance of Silkscreens cannot be overstated.
