PCB Silkscreen

Silkscreen is a legend or nomenclature, which outlines the human readable information printed on the PCB. It is a text-based information, which comprises company logos, component identifier, switch settings, test points, version numbers, and various other instruction part numbers. Silkscreening is normally performed using formulated inks. We as an industrial veteran has been practicing this artwork in PCB manufacturing facility, which also helps in the layer identification in the circuit boards.

Our Approach to PCB Silkscreening

At Twisted Traces, we use formulated colors like white and black for silkscreening. Ink-jet printers are used to image the legends directly from the digital data of the board. The printer sprays small ink droplets onto the panel to create an image. For creating a legend on the other side, ink tack is dried, and the printing is repeated. No set-up is required for ink-jet printing. This process takes less than 10 minutes in the conveyorized oven. We employ any of these methods for silkscreening on a printed circuit board.

  • Manual Screen-Printing: Manual screen printing is done when the line widths are greater than 7 mil, with the registration tolerance being 5 mil.
  • Liquid Photo Imaging (LPI): This method is utilized when the line width is greater than 4 mil.
  • Direct Legend Printing (DLP): This method is more appropriate for complex printed circuit boards.

At Twisted Traces, we have mastered manual silkscreening, over the years. Our experts will help you with appropriate silkscreening method.
