  • Publication number: 20240286389
    Abstract: A provided protective cover member is a member configured to be placed on a face of an object, the face having an opening. The protective cover member includes a laminate, and the laminate includes: a protective membrane having a shape configured to cover the opening when the protective cover member is placed on the face; and an adhesive layer. When a portion, of the protective membrane, coinciding with the adhesive layer when viewed in a direction perpendicular to a principal surface of the protective membrane is defined as a fixed portion of the protective membrane, an exposed surface of the protective membrane on a side opposite to a side, of the protective membrane, facing the adhesive layer has a region A overlapping the fixed portion when viewed in the perpendicular direction and having a contact angle of 55 degrees or more for methanol.

  • Publication number: 20240173947
    Abstract: A member supplying sheet includes two or more protective cover members each configured to be placed on a face of an object that has an opening on the face; and a substrate sheet with the two or more protective cover members arranged on a surface thereof. The protective cover members each include a laminate including: a protective membrane shaped to cover the opening when the protective cover member is placed on the face; and a carrier film. The substrate sheet includes a substrate layer and an adhesive layer laminated on the substrate layer. The carrier film is adhered to the substrate layer via the adhesive layer. The surface free energy of the carrier film on a surface thereof on the side closer to the substrate sheet is 20 mJ/m2 or more. The adhesive layer has a tack force of 100 mN/mm2 or less.

  • Patent number: 7352562
    Abstract: A solid electrolytic capacitor includes a capacitor element 2, an anode lead terminal 3 electrically connected to an anode of the capacitor element, a cathode lead terminal 4 electrically connected to a cathode of the capacitor element, and a package 5 which is made of synthetic resin and hermetically seals the capacitor element. The lead terminals are embedded in the bottom 5a of the package with the lower surfaces of the lead terminals exposed at the bottom surface of the package. The anode lead terminal and the cathode lead terminal are respectively formed with standing pieces 8 and 9 at portions corresponding to side surfaces 5b, 5c of the package, and the standing pieces have respective outer surfaces exposed at the side surfaces of the package. This structure enhances the soldering strength and facilitates the visual inspection of the quality of the soldering.

  • Patent number: 5461539
    Abstract: An electronic component is provided which comprises a resin package for enclosing inside parts. The package has a heat sensitive surface portion provided with a heat sensitive material which irreversibly discolors at a temperature higher than the soldering temperature for the electronic component. The component may be a solid tantalum capacitor, solid aluminum capacitor, diode or transistor which generates heat under abnormal operating conditions.

  • Patent number: 5363272
    Abstract: A capacitor apparatus incorporating a fuse incorporates a capacitor device having a first electrode and a second electrode; a fuse whose one end is connected to the first electrode; a first lead terminal connected to the other end of the fuse; a second lead terminal connected to the second electrode; and resin in which the capacitor device, fuse, and a part of the first and second lead terminals are molded. According to such features, fuming and ignition of the capacitor device due to an excessive current therethrough can be prevented without fail.
