Silkscreen


        If we analysis PCB surface in horizontal direction, the surface of the PCB should contain four parts: solder mask, silkscreen, surface of vias and pads. We will share some knowledge of the process and quality standard of the silkscreen in this article.

        We use silkscreen printer to print the characters on PCB, so that the characters are beautiful, the lines are clear, the ink volume is even, we are committed to perfecting the details, providing higher specifications of services, and hope that our years of accumulated manufacturing experience can give you a reference in design.
