Flexible circuits, also known globally as flex circuits, flexible printed circuit boards, flex print, or flexi-circuits, are part of the electronic and interconnection family. They consist of a thin insulating polymer film with conductive circuit patterns affixed to it, usually coated with a thin polymer for protection.So, I believe PCB meaning In the future, it will be promising to create a miracle belonging to the industry. https://www.wellcircuits.com/
The technology has been used for interconnecting electronic devices since the 1950s and is now a crucial interconnection technology in many advanced electronic products today.

Size and Weight Reduction Benefits of Flexible Circuitry
Wiring solutions that fit where rigid boards cannot.
Thin, lightweight products that are durable.
Miniaturized versions of existing technologies.
Three-dimensional packaging geometry.
A low number of device interconnects.
Shock and vibration resistance.
These benefits highlight flexible circuitry as an ideal solution for mobile consumer electronics. Inside modern devices like smartphones and laptops, flexible circuitry plays a critical role.
In mobile devices, using rigid circuitry would result in devices that are too large, heavy, and fragile to carry conveniently, exemplified by the Osborne I, the first fully powered mobile computer, weighing an intimidating 24.5 pounds. Size and weight reduction is only part of the flexible circuit story; they are also ideal for high-temperature and high-density applications.
High Temperature and High-Density Applications
Flex circuits, often made of polyimide or similar polymers, dissipate heat better than most rigid circuit board materials. This feature allows flexible circuits to be placed in locations where heat would impact the performance of rigid circuit boards.
Flexible circuit boards can withstand extreme temperatures ranging from -200＜C to 400＜C, making them desirable for borehole measurements in the oil and gas industry and preferred in industrial sensor technologies for their small size and durability.
High temperature resistance, combined with chemical resistance, excellent resistance to radiation and UV exposure, and the ability to control impedances in high-density designs, makes flexible circuits highly beneficial for manufacturers.
Why Not Make All Circuit Boards Flexible?
Flexible circuit boards are certainly useful, but they are not going to replace rigid circuit boards for all applications. Cost efficiency is the main obstacle to implementing an exclusively flexible circuit board design in a consumer product. Rigid circuit boards are less expensive to manufacture and install in a typical automated high-volume fabricating facility.
Typically, the ideal solution for an innovative product is one that incorporates flexible circuitry when necessary, and employs solid, reliable rigid circuit boards where possible to keep manufacturing and assembly costs down.
