The ink seeps in through the silkscreen image onto the panel and may require oven-curing to dry. The operator then uses a squeegee to draw the epoxy ink across the silkscreen and panel combination. The operator has to position the screen on the panel, taking care to register them precisely for proper alignment. After washing with a developer and baking in the oven, the screen with image is ready for printing. Next a laser printer creates the initial film and a UV printer imprints the image onto the emulsion. The first step in this process is to spray a polyester screen stretched across an aluminum or wooden frame with solvent resistant emulsion. The manufacturer applies the silkscreen printing over the solder mask when the boards are still in their panelized form, just before routing or v-scoring. The most common method of printing the information on the PCB surface is by depositing white non-conducting ink through a stencil. and other marks considered important for assembly.PCB manufacturers print the details on the PCB surface using a method known as silkscreen printing.Īlong with the PCB details, the silkscreen can also include:

Not only does this help identify a particular PCB for a specific product, the numbering system also helps with traceability as required by ISO and IPC standards. When designing PCBs, engineers usually assign a model number, a version number, and the version release date.
