Mother and daughter circuit board arrangement - has lugs formed on daughter board locating in holes in mother board for connections

摘要

A circuit board arrangement has a mother board (HP) onto which a daughter board (ZP) is mounted. The mechanical fixing of the boards is obtained by inserting lugs (EP) formed on the daughter board into matching apertures on the mother board. Connecting tracks on both boards are aligned and, when assembled, are permanently connected following immersion in a solder bath. The connecting lugs are separated by minimum distances. ADVANTAGE - High contact density.
