Abstract:
A process for assembling a rigid-flex printed circuit board (PCB) is presented. During operation, the process receives rigid-flex PCBs that are to be coupled together, wherein a rigid-flex PCB includes flexible PCBs coupled to rigid PCBs. The process then places the PCBs onto a carrier which is configured to: align the PCBs so that bond regions located on the flexible PCBs overlap with bond regions located on corresponding flexible PCBs, and apply pressure to the overlapped bond regions. The process then sends the carrier through a reflow oven which reflows solder on the PCBs so that the components become mechanically and electrically coupled to the PCBs. The temperature profile generated by the reflow oven and the pressure applied by the carrier cures and sets an anisotropic conductive film located in the bond regions so that the overlapped flexible PCBs become mechanically and electrically coupled together.

Abstract:
The invention is directed to a method and apparatus for electrically interconnecting multiple electronic components together by disposing the electronic components between two opposing plurality of protrusions that hold the electrical components together and establish an electrical connection therebetween. Each plurality of protrusions may be disposed in an offset arrangement with the opposing protrusions. The opposing protrusions cause the electronic components to bend and adopt a deflected geometry when they are positioned between the opposing sets of protrusions. This bending results in the electronic components being biased against each other so that electrical contacts on each electronic component may be held together and thereby form an electrical connection. As a result, the opposing sets of protrusions can be used to electrically interconnect a plurality of electrical components in the absence of clamping, adhesion, soldering, or pinching.

A hybrid structure of multi-layer substrates comprises a first multi-layer substrate and a second multi-layer substrate. The first multi-layer substrate stacks up first metal layers, first dielectric layers alternately and has VIAs. A border district of a first metal layer connects with a border district of the corresponding first dielectric layer. The border districts are separated from adjacent first metal layers and adjacent first dielectric layers. The second multi-layer substrate stacks up second metal layers and second dielectric layers alternately. A border district of a second metal layer connects with a border district of the corresponding second dielectric layer. The border districts are separated from adjacent second metal layers and adjacent second dielectric layers. The VIAs are located at the border districts of the first dielectric layers and each VIA has electric conductor therein to connect one first metal layer with one second metal layer.
