Abstract
A ceramic multi-layer wiring substrate includes a line-shaped insulation pattern arranged to extend over a plurality of surface wiring patterns and to intersect the respective surface wiring patterns, in which soldering land electrodes are defined by the insulation patterns.
Claims19
A wiring substrate comprising:
- a substrate;
- a plurality of wiring patterns disposed on the substrate;
- and
- a line-shaped insulation pattern disposed on the substrate so as to intersect the plurality of wiring patterns and so as to define a portion of each of the plurality of wiring patterns for defining land electrodes;
- wherein
- the line-shaped insulation pattern includes four line-shaped portions, each of the four line-shaped portions extends substantially perpendicular to an adjacent one of the four line-shaped portions such that the line-shaped insulation pattern has a substantially rectangular shape, and includes a disconnection portion at which ends of the line-shaped insulation pattern are spaced from one another.

A method of producing a wiring substrate comprising the steps of:
- providing a substrate;
- forming a plurality of wiring patterns on the substrate;
- and
- forming a line-shaped insulation pattern on the substrate so as to intersect the plurality of wiring patterns and so as to define a portion of each of the plurality of wiring patterns for land electrodes;
- wherein
- the line-shaped insulation pattern is formed to include four line-shaped portions, each of the four line-shaped portions extends substantially perpendicular to an adjacent one of the four line-shaped portions such that the line-shaped insulation pattern has a substantially rectangular shape, and to include a disconnection portion at which ends of the line-shaped insulation pattern are spaced from one another.
