Encapsulation: unlike a normal PCB, a flexible PCB can be placed almost anywhere, saving space and reducing the weight of a wired solution. In fact, a flexible PCB can save up to 60 percent of the weight and space of a rigid printed circuit board. Flexible printed circuit boards are thin and light and can be folded and positioned to miniaturize electronic devices. Skilled flexible circuit board technicians can use tweezers and fine tip soldering irons to manually weld very small parts under a microscope.
Durability and reliability: flexible printed circuit boards reduce the number of interconnections required, which means less soldering and contact bonding. This will leave fewer potential sources of failure, thus improving the reliability of the equipment. In addition the ductility and low quality of the flexible circuit board can significantly reduce the impact of vibration and improve the performance. Polyimide is known for its excellent thermal stability, which enables the equipment to withstand extremely high heat. As a result, flexible circuits are commonly used in military and medical applications. The main cause of circuit board failure may be related to environmental pressure. However, these can be easily avoided when using and storing devices under appropriate conditions. Unlike most rigid circuit boards, flexible circuits can be made of materials more suitable for harsh environments.
Cost saving: using flexible printed circuit board, the overall finished product assembly package size and material cost is low. Flexible circuits also reduce wiring errors and test times, thus reducing additional costs.
Flexible PCBS can be found in many common household items. Your mobile phone, computer, TV, clock and microwave oven all use FPC. Medical technologies such as scanners and X-ray machines, cars, GPS navigation devices and military technology also use flexible PCBS because they have many advantages over other circuit boards.
