Long-lasting 256-nozzle 256Jet-S has durable design and rugged stainless steel construction for noncontact printing of acid and alkaline etchants and conductive metals for direct write, printable solar photovoltaic production applications. Lines or holes of 50 μ wide x 5 to10 μ deep can be produced without damage and defects, and noncontact digital printing also lowers costs by eliminating breakage and scrap. Unit can jet conductive metal inks (such as silver ink) to digitally produce contact lines as narrow as 50 μ thick. Four models enable precision dispensing of 5, 30, 50, or 80 pl drops.
