FPC flexible printed circuit board, also called flexible board, is a kind of pcb with excellent flexibility. FPC flexible printed circuit board is made of polyester film or polyester imine, which is light, thin, high density, flexible and foldable, and has advantages that other types of circuit boards do not have. The application of FPC flexible printed circuit board in smart phones accounts for a large proportion, which can meet the needs of mobile phone screens, batteries and camera modules. Multifunctional modules of smart phones appear in the 5G era, and RF modules, folding screens and miniaturized models are inseparable from the connection of FPC flexible printed circuit boards.
The application of FPC flexible circuit must first pass the test. During testing, the high-current elastic microneedle module can transmit current and connection signals. In the current range of 1-50A, the transmission is very stable and has good connection function. Its average service life can reach more than 20w times, and its minimum value is 0. 15 mm in a small space. Its performance is reliable and its connection with FPC flexible printed circuit board is adaptable.
