Mein erster Versuch hatte wesentlich weniger Brücken dafür aber viel Pindurchführungen.
Denke so ist es einfacher?
Außerdem ist die Übersichtlichkeit etwas verlorengegangen zugunsten der Platinengröße von 100x75.

Man könnte sicher den Wannenstecker gegen eine Buchsen oder Stiftleiste tauschen - ist so etwas überdimensioniert -

Pindurchführungen vergisst man gerne zu löten. Eine Brücke ist ein Bauteil wie jedes Andere auch. :wink:
Löten verbindet ...manchmals. :mrgreen:

Habe mit Pindurchführungen augenscheinlich das falsche Wort gewählt.
Ich meinte das durchführen der Leiterbahn zwischen den Pins eines ICs.

Ich dachte du meinst eine 2 seitige Leiterplatte wo die "Vias" nur bei Bauteilepins vorkommen.
