Picture of a tin-bridge

This picture shows another frequent mistake - a tin-bridge ("short circuit"). (black frame)
When the gap between two lands is pretty narrow the solder may link those two as can be seen here.

SOLUTION:Just apply as much solder as necessary to cover the land and the wire.

NOTE: It is very important to hold the soldering joint in such way to head just one land at a time.

Ursache: Lötzinn wurde zu lange erwärmt, dadurch ist das Flußmittel im Lot verdampft und die Lötstelle geht keine Verbindung mit dem Zinn mehr ein.
