ABSTRACT:
An apparatus and method for mounting and connecting a plurality of integrated circuit chip dice to a printed circuit substrate by means of a small circuit board (such as a Mini-Board) that may be adapted to attach and connect into a plurality of different types of printed circuit board systems. A pattern of conductors that monotonically increases in pitch and width from a central point on a planar structure to the perimeter edge of the structure allows matching of any type of printed circuit board connections. A standard Mini-Board may be fabricated and tested before attaching to an electronic system printed circuit board. Repair and rework is easily facilitated with a minimum amount of damage to a printed circuit board by utilizing the present invention. A plurality of active and passive electronic components may also be attached and connected to the planar structure of the present invention. A hybrid mini-system may be fabricated and tested before connecting it into a system printed circuit board.
