Zusammenfassung: | To propose a printed board that can prevent an electrolytic solution leaking from an electrolytic capacitor from reaching a wiring pattern or other mounting components, and has less restrictions caused by the prevention.SOLUTION: A printed board 10 includes a substrate 20, an electrolytic capacitor 30 provided on the substrate 20, a wiring pattern 41 or other mounting components 42 provided on the substrate 20, and a liquid stop pattern 50 formed on the substrate 20 so as to swell above the substrate 20. The liquid stop pattern 50 extends continuously along the substrate 20 such that both ends reach the outer edge of the substrate 20. The liquid stop pattern 50 divides the substrate 20 into a region A1 surrounding the electrolytic capacitor 30 together with the outer edge of the substrate 20 and another region A2 in which the wiring pattern 41 or other mounting components 42 are arranged.SELECTED DRAWING: Figure 1
【課題】電解コンデンサから漏出した電解液が配線パターンまたは他の実装部品に到達することを抑制でき、かつ、これによって生じる制約が少ないプリント基板を提案する。【解決手段】プリント基板10は、基板20と、基板20上に設けられた電解コンデンサ30と、基板20上に設けられた配線パターン41または他の実装部品42と、基板20よりも上方に盛り上がるように基板20上に形成された液止めパターン50と、を備えている。液止めパターン50は、両端が基板20の外縁に到達するように基板20に沿って連続的に延びている。液止めパターン50は、基板20の外縁とともに電解コンデンサ30を囲む領域A1と、配線パターン41または他の実装部品42が配置された他の領域A2と、に基板20上を区画している。【選択図】図1 |
