Abstract:
A pattern-forming method for forming a conductive circuit pattern, the pattern-forming method including the steps of: preparing a pattern-forming composition composed of: Cu powder; solder particles for electrically coupling the Cu powder; a polymer resin; a deforming agent that is selected from among acrylate oligomer, polyglycols, glycerides, polypropylene glycol, dimethyl silicon, simethinecone, tributyl phosphare, and polymethylsiloxane, and that increases bonding force between the Cu powder and the solder particles; a curing agent; and a reductant; forming a circuit pattern by printing the pattern-forming composition on a substrate; heating the circuit pattern at a temperature effective to cure the pattern-forming composition and provide the conductive circuit pattern; and electrolytically plating a metal layer onto the conductive circuit pattern. A circuit pattern having superior conductivity is formed at low cost.
Abstract:
To provide a printed circuit board that allows for easy exchange of only a deterioration detection conductor, and can reduce costs. A printed circuit board includes: a main printed circuit board in which a wiring pattern is formed on an insulated substrate; and a deterioration detection wiring board in which deterioration detection wiring (deterioration detection wiring pattern) which is wiring having a form whereby deterioration is promoted compared to the wiring pattern on the insulated substrate is formed on a separate insulated substrate from the main printed circuit board, and is exchangeably connected to the main printed circuit board in a vicinity thereof by way of a replacement-enabling connection part. One mode of the replacement-enabling connection part of the printed circuit board is a connection part (solder joint) constituted by solder, another mode thereof is a connection part (electrically conductive adhesive connection part) constituted by electrically conductive adhesive, and yet another mode thereof is a connection part (cable) constituted by a cable.
