  • Liquid coverlays for flexible printed circuit boards
    Patent number: 9670306
    Abstract: The present invention relates to curable liquid coverlay compositions comprising polyamideimide resins for use in curable compositions for use as protective coverlay coatings for metal clad laminate materials in electronic components, such as flexible circuit boards. In particular, the invention relates to liquid coverlay compositions comprising polyamideimides having a terminal isocyanate group blocked by a thermally-dissociatable isocyanate-blocking group and the use of such compositions in preparation of flexible electronic components.
    Type: Grant
    Filed: March 16, 2010
    Date of Patent: June 6, 2017
    Assignee: Sun Chemical Corporation
    Inventors: Stephen Anthony Hall, Richard Charles Davis, Simon Richard Ford, Matthias Klaus, Karl-Heinz Ognibeni
  • Polyamideimide adhesives for printed circuit boards

  • Device for indicating the degree of exhaustion of an adsorption filter
    Patent number: 4332679
    Abstract: A filtering apparatus for indicating the degree of exhaustion of an adsorption filter which includes a mechanical filter and a pressure meter for detecting the difference in pressure between a point downstream and a point upstream of the mechanical filter to provide an indication of the degree of exhaustion of the adsorption filter. The mechanical filter may be an internal type filter or a surface filter and it may be either series-connected or connected in shunt with the flow path of the adsorption filter.
