In the PCB application, there are a multitude of copper base materials with different pre-treatments. Lunaris is the only solution in which print heads and resist are manufactured by the same vendor – Océ. Not only have we sourced the best and most reliable print heads, the heads and resist are tuned for optimal performance. We consider this to be a mandatory requirement for a real world industrialized solution for the imaging of etch resist. So much so, we’ve given it a name... micro-procedé.
Micro-procedé facilitates a stable jetting print head; controlling jet frequency, jetting angles and drop size, whilst eliminating cross talk and satellite formation.
So now we’ve got stable jetting of resist in the form of known drop sizes, known angles, known frequency and known timing. Next we need to control the flow and how the droplets interact with each other on the substrate. This is taken care of by the Print Strategy – something unique to Lunaris. It operates within the resist gelling window to ensure that the final etch resist image is a perfect facsimile of the CAM data. Without a Print Strategy, the resist flow would be uncontrolled with disastrous results.
