Hello...

I'm start journey to make inkjet head for printing pcb's. As far I know
all direct print inkjet have problem's with ink and head itself is
problematic. So I was just trying to make one pixel piezo head capable
to jet etch resist for making traces and after that to print real solder
resist mask.

As far I know the head itself is made from 3 components. The chamber
with variable volume, the input port capilar and the nozle.

I was try to make capilar just with zigzag milling the pcb just 0.1mm
deep and after that gluing transparent foil ontop. The capilar is 15cm
long and seems that is ok. The chamber is made inside same piece just
the depth is set to 0.5mm and is covered with piezo buzzer glued on top.
For the nozzle I just try if I can do that small hole and I can. The
hole of 0.08mm can be done without some special tool.

See photos.

Slavko.
