Abstract:
The invention relates to an arrangement for connecting a hybrid circuit to a mother board, the hybrid circuit comprising a printed circuit board (1) of an insulating material, with foils on both sides, components fixed to the printed circuit board, and printed circuit board legs (2) by means of which the hybrid printed circuit board is connected to the mother board. The purpose is to achieve a connection which is maximally easy to manufacture and at the same time electrically and mechanically reliable. To achieve this, the legs of the printed circuit board consist of projections (2) in the board (1) itself, and the mother board has apertures corresponding to the legs, the apertures not being copper-plated throughout, in which case the earth foils and conductor foils in the projections (2) are connected to the foils of the mother board at the edges of the apertures. The apertures in the mother board are preferably oval, corresponding in width to the thickness of the legs (2).

Abstract:
A printed circuit board (PCB) assembly may include a motherboard PCB with one or more plated holes and a daughterboard PCB with one or more plated fingers extending from a lower edge of the daughterboard PCB. The plated fingers may have a rectangular and/or square cross section. The plated fingers may be plated on four sides that define the rectangular cross section. Each of the plated holes may be configured to receive a respective plated finger, for example, such that a lower portion of the plated fingers extend beyond a lower surface of the motherboard PCB. Each of the plated holes may be configured to be electrically connected to a respective plated finger via a solder joint. The solder joint may extend around the respective plated finger. The solder joints for the plated fingers may be configured to secure the daughterboard PCB to the motherboard PCB.
