Latest Patents

Kapp-Schwoerer holds a patent for a "Curtain coating process for producing thin photoimageable coatings." This process involves a meticulous technique where a metallic-layered substrate is conveyed beneath a free-falling curtain of a photopolymerizable substance. The substance, possessing a viscosity of 30-120 seconds DIN cup 4 at 25 degrees Celsius, is applied from a height of 5-25 centimeters above the board. The result is a coating that achieves a dry film thickness of up to about 1.5 mils after the surfaces are dried. The coated surfaces are then readied for photoimaging, developing, etching, and stripping operations, revolutionizing the methods used in the electronics industry.
