If there are any true constants in the formula for the evolution of modern electronics, the push to work at increasingly smaller scales arguably tops the list. Where convenience and practicality ...

Building electronics in unconventional form factors with high packaging density is possible thanks to three-dimensional circuit designs using flex and rigid-flex printed circuit boards (PCBs).

Flexible printed circuit boards (PCBs) aren’t much different than rigid boards during the design phase, except that the designer must account for the mechanical complexity associated with flex ...
