Directly Printed Etchmask

Patterning Technologies Limited has developed its patented etch masking technology for use in many different applications including photochemical machining. printed circuit boards, die cut tooling. and displays. 1be technology enables reduction of both cost and time by eliminating the steps of photolithography currently employed in preparing the surfaces to be etched. Improvements have been made in achievable resolution down to 100 microns today, with 50 microns being achievable in the foreseeable future. The cured etch mask fluid has been demonstrated to withstand the conditions of etching for up to 2 hours. PTL is able to offer a complete process including equipment and fluid tailored to specific requirements.
