The printer is used to apply a liquid solder mask or marking paint to the surface of a PCB blank.
An important part of the identification system is the labeling of printed circuit boards, which makes it possible not only to track products at stages of the technological process, but also to use it at all stages of the life cycle.
The marking may contain information about the manufacturer, serial number, additional technological information, an indication of belonging to a particular type of device.
There are different ways of applying:
Classic – application of marking paint using a stencil.
Inkjet-drop – non-contact application, fully automatic, allows you to print up to four lines at a time.
Laser is a fully automated process, which, in addition to high accuracy of application, also allows you to check the marking for compliance.
Labeling is the most technologically accessible and inexpensive way, in which automated systems with a built-in printer are used, you can also glue labels manually when manufacturing small batches of printed circuit boards.
