Abstract:
A aspect of the present disclosure provides a base material with a transparent conductive film on or above the base material. The transparent conductive film includes a conductive layer containing metal wires, and a protective layer being located on a side of the conductive layer and containing a resin and a particle, the side not opposing to the base material. The particle is soluble in an acidic etching solution, and the resin is resistant to the acidic etching solution.
Abstract:
A stretchable flexible substrate according to one aspect of the present disclosure includes: an electronic component; a first insulating layer located around the electronic component and having first and second main surfaces facing each other; a first metal layer that is in contact with the first main surface; a second metal layer that is in contact with the second main surface and electrically connected to the electronic component; and a second insulating layer that seals the electronic component, first insulating layer, and second metal layer, in plan view, a curved wiring portion extending from a central portion made up of at least the electronic component, portions of the first insulating layer and first and second metal layers, the curved wiring portion being made up of at least other portions of the first insulating layer, first and second metal layers, and the curved wiring portion being curved at least partially.
Abstract:
An electronic component package according to one aspect of the present disclosure includes a metal pattern layer having a first principal surface and a second principal surface, an electronic component disposed on the first principal surface and electrically connected to the metal pattern layer, at least one metal member disposed on the first principal surface and electrically connected to the metal pattern layer, a sealing resin layer disposed on the first principal surface, the electronic component and the at least one metal member, and an insulating layer disposed on the second principal surface. The at least one metal member is thicker than the electronic component. In plan view, the at least one metal member is disposed on an area of the first principal surface, the area including an end of the first principal surface. The at least a part of the metal pattern layer is exposed from the insulating layer.
Abstract:
A flexible substrate is provided with: a stretchable sheet; a member located on the sheet; and a stretchable strip connected to the member, and located on the sheet. When the amount of extension of the sheet is equal to or less than a predetermined value, the sheet has a first elastic modulus, and when the amount of extension of the sheet exceeds the predetermined value, the sheet has a second elastic modulus that is greater than the first elastic modulus and greater than the elastic modulus of the strip.
Abstract:
A base material with a transparent conductive film on or above the base material is provided. The transparent conductive film includes a conductive layer; and a protective layer being located on a side of the conductive layer and containing a first resin, the side not opposing to the base material. The transparent conductive film includes a conductive portion and a non-conductive portion in a plan view. The conductive layer contains no metal wires in the conductive portion or contains less metal wires per unit area in the non-conductive portion than the conductive layer contains the metal wires per unit area in the conductive portion. The protective layer contains a particle in the conductive portion, and includes an aperture penetrating the first resin in a thickness direction in the non-conductive portion. The particle is soluble in an acidic etching solution, and the first resin is resistant to the acidic etching solution.
