An adhesive film according to the present invention includes a resin composition layer (layer A) for an interlayer insulating layer, a thermosetting resin composition layer (layer B), and a support film (layer C), and the layer C, the layer A, and the layer B are sequentially arranged in this order. The layer A is a resin composition which contains a thermosetting resin (a1) and an inorganic filler (b1) having a specific surface area of 20 m2/g or more, and the mass ratio of the thermosetting resin (a1) to the inorganic filler (b1) is within the range from 30:1 to 2:1. The layer B contains a thermosetting resin composition which is in a solid state at a temperature lower than 40° C. but melts at a temperature of 40° C. or higher but lower than 140° C. Consequently, the adhesive film according to the present invention can solve problems in a laser process and a desmear removal process following the laser process and can form a conductor layer which has a high adhesion strength even on an interlayer insulating layer having a smooth surface-roughened state.

An etching solution comprising (A) an amine as a solvent, (B) an alkali metal compound, and (C) an alcohol as a solvent, this etching solution being a non-aqueous solution. This etching solution is-effective for etching a cured epoxy resin layer for forming holes for interstitial via holes having a small diameter, in the production of a multilayer printed circuit board. This etching solution is particularly effective for etching a cured epoxy resin layer formed from a thermosetting epoxy resin composition including (a) an epoxy resin, (b) a crosslinking agent, and (c) a polyfunctional epoxy resin, which forms a thermosetting copper-clad adhesive resin sheet which covers an interlayer circuit plate of a multilayer printed circuit board.

摘要:
In an information signal editing device, when a user specifies a desired reproduction section or reproduction start position, a management information file recorded in a memory is rewritten into a second management information file which is created on the basis of the specified information, and a second information file is set on the basis of the second management information file. The information signal editing device constructed as described performs arbitrary virtual editing when a DVD-RAM disk is non-rewritable, whereby the user can obtain a desired reproduction signal.
摘要:
The invention aims to provide a resin primer which can stick an insulator layer to a conductor foil whereof the surface is not much roughened with sufficient adhesive force, a conductor foil with resin, a laminated sheet and a method of manufacturing same. The resin primer of the invention comprises a resin having film-forming ability and a breaking energy of 0.15 J or more. The conductor foil with resin of the invention comprises a resin layer comprising a conductor foil and the aforesaid resin primer. Further, the laminated sheet of the invention comprises the conductor foil, an insulating layer disposed facing the conductor foil, and a resin layer comprising the aforesaid resin primer disposed between the conductor foil and insulating layer so that it is in contact therewith. This laminated sheet can be manufactured by heating and pressurizing a laminate comprising the aforesaid conductor foil with resin, and a prepreg laminated on this resin layer.
摘要:
In relation to telephone sets connected together over a radio channel, to enable a telephone set of a calling party to readily identify whether or not a call acknowledgement from a receiving party has been detected. After a call has been originated by way of a keyboard 22 of a radio telephone set, a call acknowledgement signal detection section 17c monitors a call acknowledgement signal transmitted from the calling party by way of a base station 30. When the call acknowledgement signal detection section 17c detects the call acknowledgement signal transmitted from the receiving party, a specific call acknowledgement sound signal is output from an audio output section 21. Further, a specific screen color is displayed on a display section 20. If no call acknowledgement signal from the receiving party is detected and the call acknowledgement detection section 17c determines that no call acknowledgement from the receiving party has been detected, a call is automatically re-originated by means of an automatic call originating function, thereby enabling easy identification of a call acknowledgement. Further, since the call is automatically re-originated if no call acknowledgement from the receiving party is detected, the operations required for the calling party are simplified.
