20110175700 | CONDUCTIVE POLYMER ELECTRONIC DEVICES WITH SURFACE MOUNTABLE CONFIGURATION AND METHODS FOR MANUFACTURING SAME - Surface-mountable conductive polymer electronic devices include at least one conductive polymer active layer laminated between upper and lower electrodes. Upper and lower insulation layers, respectively, sandwich the upper and lower electrodes. First and second planar conductive terminals are formed on the lower insulation layer. First and second cross-conductors are provided by plated through-hole vias, whereby the cross-conductors connect each of the electrodes to one of the terminals. Certain embodiments include two or more active layers, arranged in a vertically-stacked configuration and electrically connected by the cross-conductors and electrodes in parallel. Several embodiments include at least one cross-conductor having a chamfered or beveled entry hole through the upper insulation layer to provide enhanced adhesion between the cross-conductor and the insulation layer. Several methods for manufacturing the present surface-mountable conductive polymer electronic devices are also provided. | 07-21-2011 |
20140077923 | CONDUCTIVE POLYMER ELECTRONIC DEVICES WITH SURFACE MOUNTABLE CONFIGURATION AND METHODS FOR MANUFACTURING SAME - Surface-mountable conductive polymer devices include a conductive polymer layer between first and second electrodes, on which are disposed first and second insulation layers, respectively. First and second planar conductive terminals are on the second insulation layer. A first cross-conductor connects the second electrode to the first terminal, and is separated from the first electrode by a portion of the first insulation layer. A second cross-conductor connects the first electrode to the second terminal, and is separated from the second electrode by a portion of the second insulation layer. In some embodiments, at least one cross-conductor includes a beveled portion through the first insulation layer to provide enhanced adhesion between the cross-conductor and the first insulation layer, while allowing greater thermal expansion without undue stress. In other embodiments, these advantages are achieved by having at least one cross-conductor in physical contact with a metallized anchor pad on the first insulation layer. | 03-20-2014 |
20140239804 | DEVICES AND METHODS RELATED TO FLAT GAS DISCHARGE TUBES - Disclosed are devices and methods related to flat gas discharge tubes (GDTs). In some embodiments, a plurality of GDTs can be fabricated from an insulator plate having a first side and a second side, with the insulator plate defining a plurality of openings. Each opening can be covered by first and second electrodes on the first and second sides of the insulator plate to thereby define an enclosed gas volume configured for GDT operation. Various examples related to such GDTs, including electrode configurations, opening configurations, pre-ionization features, grouping of a GDT with another GDT or device, and packaging configurations, are disclosed. | 08-28-2014 |
