When to Use Rigid and When to Use Flexible
Rigid PCBs typically cost less than flex circuits. I say
“typically” because when considering the total cost of ownership
there are some applications that, when using flexible PCBs, may be
less expensive compared to using rigid PCBs. To get a true and
accurate understanding of the total cost of ownership, you first
need to appreciate the fact that flex circuits may eliminate the
need for components such as connectors, wire harnesses, and other
circuit boards. By removing these components from a design,
material cost, labor and assembly cost, and scrap cost are all
reduced.
Many electronic devices (laptop and desktop computers, audio keyboards, solid-state drives (SSDs), flat-screen TVs and monitors, children’s toys, and various electronic gadgets) employ rigid PCBs instead of flexible PCBs. However, flex circuits may be found in ultra-compact and/or high-performance devices, including GPS units, tablets, smart phones, cameras, and wearables.
Greater sophistication is not the only reason to use flex circuits; low-tech applications (such as under-the-counter LED lights, see figure below) may utilize flex circuit technology, in some cases because it makes installation much easier.
