Abstract
A multi-layer rigid-flex circuit (20) is formed of a number of flexible layers (62-70) on a rigid substrate (100) with individuals ones of the layers having laterally projecting arms (32,38) that define flexible circuit connections to individual ones of a number of ceramic circuit boards (10,12,14,16). The laterally projecting flexible arms (32,34,36,38) are each formed with gold dot or projecting feature pressure contacts (40a-40g) which are pressed against mating sets of circuit board contact pads (40a-40g) by a clamping bar (120) that is bolted to the rigid circuit board. Thus the interconnections between the rigid-flex circuit and the circuit boards are effectively built into the rigid-flex circuit, requiring only a clamp to complete the connection.
