Flexible electronics offers a few benefits. A patent for the flexible electronics or flexible printed wiring appeared in the early 1900s. Albert Hansen would be one of the first individuals to shape the creation of flexible circuit boards. It would be in the1950s there will be more advances made by inventors, Victor Dahlgren, and Royden Sanders. Japan has made many uses of flexible printed wiring. Flexible printed wiring is growing in popularity. There are a few types of flexible electronics.
Benefits of Flexible Circuit Boards
Any type of rigid flex circuit boards offer several benefits. The flex circuit board is utilized because it is lightweight. The use of lightweight flex circuit boards can help reduce package size. A flexible circuit board the circuit board can withstand high temperatures. The resistance to high temperatures makes the circuit board a popular component for electronics utilized by military branches. The other benefits of flexible electronics are:
- Resistance to UV and radiation exposures
- Flexibility allows use in small devices
- Reduce circuit failure
- Minimizes vibration
The use of flexible electronics is good for devices who need protection from UV rays. It is also good for components that will be exposed to some radiation. The flexible printed wiring can be easily folded to fit small devices. The circuit board can be easily shaped to fit devices. The flexible electronics has fewer connects, and fewer connects will reduce the possibility of circuit failure. Flexible electronics are good to utilize when a reduction of shock is required. Vibration is easily minimized with the use of flexible electronics. The benefits can be offered in several types of flexible printed wiring.
Types Of Flexible Circuit Boards
Flexible circuit boards are often used in the aerospace industry and military projects. The single-sided flex circuits are used in automotive lighting. The circuit board can be used in LED glass. Single-sided flex circuits can be created with or without protective coatings. The single-sided flex circuit with protective coating is more common of the types to be utilized. Sculptured flex circuits will utilize copper conductors. The circuit is flexible and has a thin construction. Double-sided flex circuits can have two conductor layers. The common double-sided flex circuit will have plated through holes. The advantage of using the type of circuit it makes crossover connections easy. A double-sided flex circuit can be used in the circuitry of the mousepad that connects it to the motherboard of a laptop. Multilayer flex circuits consist of three or more layers of conductors. It utilizes plated through holes. The multilayer flex circuits are good when significant flexibility is necessary for a project. Rigid-flex circuits are a combination of rigid and flexible substrates into a single circuit. Both parts are laminated together. Polymer thick film flex circuits will be printed on polymer-based film. The type of circuit is made up of a single layer conductor. Polymer thick film circuits are often used in keyboards. The applications with low-voltage will utilize the polymer thick film flex circuits. The use of the circuitry can be cost-effective.
