In the world of spray etching equipment, what is the minimum
spray pressure generally accepted before the quality of the
etching becomes degraded (assuming the nozzles still hold
the spray pattern) ?
I have heard of pressure ranges between 15 psi and 40psi (1
to 3 bar) being used. Does anyone know if a pressure of 8
psi (0.55 bar) can be practical ?
