Editing Flexible electronics (section)

==Manufacturing==
Flexible printed circuits (FPCs) are made with a photolithographic technology. An alternative way of making flexible foil circuits or [[flexible flat cable]]s (FFCs) is laminating very thin (0.07&nbsp;mm) copper strips in between two layers of [[Polyethylene terephthalate|PET]]. These PET layers, typically 0.05&nbsp;mm thick, are coated with an adhesive which is [[thermoset]]ting, and will be activated during the lamination process. FPCs and FFCs have several advantages in many applications:
* Tightly assembled electronic packages, where electrical connections are required in 3 axes, such as [[cameras]] (static application).
* Electrical connections where the assembly is required to flex during its normal use, such as folding [[cell phones]] (dynamic application).
* Electrical connections between sub-assemblies to replace wire harnesses, which are heavier and bulkier, such as in cars, [[rocket]]s and [[satellites]].
* Electrical connections where board thickness or space constraints are driving factors.

===Advantage of FPCs===
* Potential to replace multiple rigid boards or connectors
* Single-sided circuits are ideal for dynamic or high-flex applications
* Stacked FPCs in various configurations

===Disadvantages of FPCs===
* Cost increase over rigid PCBs
* Increased risk of damage during handling or use
* More difficult assembly process
* Repair and rework is difficult or impossible
* Generally worse panel utilization resulting in increased cost
