When new clients come to us asking for assistance in bringing a product to market, it's often because they've become overwhelmed by the sheer number of options when it comes to PCB assembly and manufacturing.
Rapid technological changes have created an environment where even seemingly-minor issues like those of electronic interconnect cables are far more important than they seem.
Electronic interconnect cables are exactly what they sound like. The wiring on the underside of a PCB is designed to carry current, not data. So on a modern PCB with multiple processing units and other "smart" components, they need additional wiring to carry the data between those components. Additionally, they're needed to carry data to/from any external sensors, displays, or other components the user may interact with.
