A marking print is helpful for error-free manual assembly, but also for including a revision number on the circuit board. Multi PCB can provide marking prints in the colours white, yellow, and black.
！Solder pads should never be overprinted, because this may lead to problems during soldering, assembly, and in the E-Test. If we should detect an overprinted solder pad (spacing < 150µm), then Multi PCB will remove the marking print at this location. Relevant for the definition of the solder pads is the solder pad exemption. The marking print is usually automatically clipped with a spacing of 100µm to the solder-stop edge.

Marking print proposalThe spacing between solder pad and marking print should be at least 150µm.
Always avoid overprinting solder pads!
Note for EAGLE users
Before exporting your data, you should always activate the option "Always vector font", which is found under: Options / User interface. Otherwise your marking print will very probably be incorrectly applied.
