Multilayer PC Connector

Printed-circuit (PC) board A is orthogonally mounted and electrically interconnected to an underlying PC board B by connectors 10.

Each of the connectors 10 is made from a flat PC flexible cable having one or preferably more layers (laminated together), e.g., layers 11, 12. Connectors 10 are of the type which are formable into various shapes and which retain the shapes into which they are formed. Accordingly, each connector 10 is formed from an appropriate length of this type cable and shaped into a right angle or L- form. Also, inner layer 11 is partially stripped away at its transverse edges. As a result, the conductors 13 of the resultant shorter layer 11 are adapted to be bondable to the pretinned inboard PC pads of boards A and B, e.g., respective pads 1 and 2, and conductors 14 of longer layer 12 are adapted to be bondable to the pretinned outboard PC pads, e.g., pads 3 and 4 of boards A and B, respectively.

Apertures or holes 15 in connectors 10 are provided where needed to allow heat transfer accessibly to inboard pads 1, 2 which are to be solder reflow bonded to the conductors 13 of layer 11. At the sites of the particular conductors 13, 14 to be bonded, the associated insulation of the connector 10 is removed. One way, for example, would be to strip away the insulation along the transverse edge of the particular layer 11, 12 and remove the so exposed conductors not desired to be bonded. Thus, as shown by way of example, the insul...
