Abstract
An electrical sub-circuit assembly is secured to a printed circuit board by providing a printed circuit board with a basin, the printed circuit board having electrical pathways leading to the top or side or on the bottom of said basin, and positioning an electrical sub-circuit assembly in the basin, the sub-circuit assembly having dimensions corresponding to the size of the basin so as to be a close fit therein and having electrical connections which locate adjacent corresponding electrical pathways on the printed circuit board. The sub-circuit assembly is secured in the basin, and the electrical connections on the sub-circuit assembly are connected to the corresponding pathways on the printed circuit board.
Claims6
An electrical circuit assembly comprising a printed circuit board and an electrical sub-circuit assembly secured thereto, wherein:
- the printed circuit board has an upper surface and a basin defined therein, and electrical pathways extend along the upper surface of the printed circuit board and terminate adjacent the basin;
- the sub-circuit assembly has dimensions corresponding to the size of the basin, the sub-circuit assembly is secured in the basin and is a close fit therein, the sub-circuit assembly has an upper surface having electrical connections thereon adjacent the periphery of the upper surface of the sub-circuit assembly;
- the electrical connections on the upper surface of the sub-circuit assembly are each electrically connected to a respective electrical pathway on the upper surface of the printed circuit board across a respective gap between the upper surface of the sub-circuit assembly and the upper surface of the printed circuit board;
- the upper surface of the printed circuit board adjacent the basin and the upper surface of the sub-circuit assembly are substantially coplanar with one another;
- and
- the sub-circuit assembly is secured in the basin by adhesive and the printed circuit board has reservoirs adjacent the basin receiving excess adhesive from the securing operation.
