Abstract
A circuit board comprises one or more first electrical conductors (-) in a first portion of the thickness of the circuit board, one or more second electrical conductors () in a second portion of the circuit board, at least one via-conductor () providing a galvanic current path between the first and second electrical conductors, a hole extending through the first and second portions of the circuit board, and an electrically conductive sleeve () lining the hole and having galvanic contacts with the second electrical conductors. The thermal resistance from the electrically conductive sleeve to the first electrical conductors is greater than the thermal resistance from the electrically conductive sleeve to the second electrical conductors so as to obtain a reliable solder joint between a part of the electrically conductive sleeve belonging to the first portion of the circuit board and an electrical conductor pin () located in the hole.
