Flexible Circuits, They Bend for All of Your Electronic Devices
Class I flexible circuits are a part of every type of device that you can conjure up. They do not need a whole of attention while wearing them because they are not exposed to rough environmental factors that usually results in the malfunction of the device. Some examples of flexible PCB devices would be halter monitors (measures your heart rate), calorie counters, and devices that measure the number of steps you take during the time you are wearing the device.
Class II (Two)
Class II flexible printed circuit boards are utilized for industrial and commercial industries. They also are not usually exposed to tough environmental factors because of this their standards are based on quality and efficient solder joints making connections within the circuitry.
Class III (Three)
Class III flexible printed circuit boards are used for military, aerospace, and medical electronics. Since these boards are used for such important tasks their standard requirements must meet an extremely demanding testing process before they are deemed ready to function.
