In this method, Acrylic ink is applied on a PCB with the help of an inkjet printer. It is relatively expensive but offers utmost precision and accuracy.

LPI enables better precision compared to manual screen printing. In this method, a liquid epoxy is coated onto the laminate and dried in UV light after which the board is cured. This process has some similarities with the one used for the application of soldered mask. Liquid Photo Imaging (LPI): This method is utilized when the line width is greater than 4 mil.This method is easy to implement however, it is applied where precision is not a critical parameter. The ink is cured by baking the PCB in an oven. In this method, a stencil of the text is used through which the ink is pushed onto the laminate.

Manual Screen Printing: This method is applied when the line widths are greater than 7 mil, with the registration tolerance of 5 mil.We employ any of these methods for silkscreening on a printed circuit board: This process takes less than 10 minutes in a conveyorized oven. No additional setup is required for inkjet printing. For creating a legend on the other side, the ink tack is dried, and the printing is repeated. The printer sprays small ink droplets onto the panel to create an image. We use inkjet printers to image the legends directly from the digital data of the board. Our Approach to PCB SilkscreeningĪs a silkscreen circuit board manufacturer with vast experience, we, at Twisted Traces only use formulated colors such as white and black for silkscreening. Usually we use standard font style and size however, it can be customized as per your requirement. We do this at our state-of-the-art PCB manufacturing facility. Twisted Traces is an old and established player in PCB manufacturing and has been practicing this artwork to help layer and component identification in circuit boards.

They are usually non-conductive epoxy inks. Silkscreening is normally performed using formulated inks. These indicate the names of various mounted components, soldered parts, test points, part numbers, date codes, manufacturer’s logo, warnings, and so on. It comprises some letters and numbers, which are readable to the normal human eye. Silkscreen is the nomenclature or pieces of information printed on PCBs, most commonly in white ink.
