Latest Patents

Joshua holds a patent for a "Method of making a Z axis interconnect circuit." This method involves creating Z-axis interconnections between adjacent circuit layers with electrically conductive traces. The process includes connecting a conducting member made of a deformable material to a circuit board layer and depositing an adhesive layer over an adjacent circuit board layer. The adjacent circuit layers are aligned, with the conducting member substantially collinear with the conductive traces of the adjacent circuit layers. By applying pressure, the conducting member penetrates the adhesive layer and deforms until it 'cracks.' This cracking exposes fresh (unoxidized) material that contacts a conductive trace, effectively joining the circuit layers together and creating a low resistance electrical connection. The adhesive serves to bound the expansion of the deformable conducting member, reducing any potential contacts with adjacent conducting members.
