20080308003 | UV inkjet resist - A UV curable, etch-resistant ink composition for ink jet printing of variable information on printed circuit boards and for printing the circuit boards themselves. The ink composition of the invention includes a novel thermal stabilizer for preventing the ink composition from hardening and gelling in the print head when heated. | 12-18-2008 |
20090191491 | Method of Creating an Image in a Photoresist Laminate - A process for creating an image in a dry-film resist laminate. The dry-film resist laminate comprises in order, a peelable top layer, a layer of dry-film resist, a clear or translucent coating layer, and a peelable bottom layer. The top layer is peeled from the laminate and the laminate is applied to a surface using heat and pressure. Thereafter, an image is created in the layer of dry-film resist and the resist is developed to remove uncured portions of the layer of photoresist along with the clear or translucent coating layer. | 07-30-2009 |
20110079578 | Nickel-Chromium Alloy Stripper for Flexible Wiring Boards - A nickel-chromium alloy etching composition comprising sulfuric acid, a source of chloride ions, including hydrochloric acid or sodium, potassium or ammonium chloride, and a sulfur compound comprising a sulfur atom with an oxidation state between −2 to +5, such as thiosulfate, sulfide, sulfite, bisulfite, metabisulfite and phosphorus pentasulfide that can efficiently remove nickel-chromium alloy in the presence of copper circuits is disclosed. | 04-07-2011 |
