摘要:
In an electronic component having a wiring and/or an electrode prepared through firing of a paste or in an electronic component having a wiring in contact with a glass or glass ceramic member, provided is an electronic component using a Cu-based wiring material which less suffers from increase in electric resistance due to oxidation, which less causes bubbles in the glass or glass ceramic, and has satisfactory migration resistance. The Cu—Al alloy powder includes a Cu—Al alloy powder including Cu and, preferably, 50 percent by weight or less of Al; and an aluminum oxide film having a thickness of 80 nm or less and being present on the surface of the Cu—Al alloy powder. The powder, when compounded with a glass or glass ceramic material to give a paste, can be used to form wiring (interconnections), electrodes, and/or contact members.

摘要:
The invention relates to an epoxy resin molding material for sealing, comprising an epoxy resin (A), a curing agent (B), and a colorant resin mixture (C) wherein a resin (C1) and a colorant (D) having an electric resistivity of 1×105Ω·cm or more are beforehand mixed with each other. This can provide an epoxy resin molding material for sealing which is good in moldabilities such as fluidity and curability, and colorability, and which does not cause a short circuit failure based on an electroconductive material even when the material is used in a package wherein the distance between pads or wires is small; and an electronic component device equipped with an element sealed therewith.
摘要:
The invention relates to a curing accelerator for a curing resin obtained by reacting a phosphine compound (a) with a compound (b) having at least one halogen atom substituted on an aromatic ring and at least one proton atom which can be discharged, and subjecting the reaction product to dehydrohalogenation, a curing resin composition containing the curing accelerator, and an electronic component device having a device component encapsulated with the curing resin composition. The curing accelerator exhibits superior curability under moisture absorption, flow properties, reflow cracking resistance and high-temperature storage characteristics.
