Latest Patents

One of Urmi Ray's latest patents is an optical fiber preform cleaning method. This method involves cleaning glass preforms by contacting each preform with supercritical carbon dioxide, which effectively dissolves residual index-matching oil. The liquefied carbon dioxide is then converted back to gaseous form, allowing for the separation and recovery of the index-matching oil. This process is designed to be environmentally friendly, as it results in substantially no waste.

Another significant patent is a method for stripping conformal coatings from circuit boards. In this process, the surface integrity of the protective covercoat is altered, for example, by making incisions. The coated circuit board is then subjected to supercritical carbon dioxide in a processing chamber, which allows the coating to be easily lifted from the board, facilitating repairs.
