Our loyal customer base is built upon RFP’s unparalleled customer service and response time.”Multilayer flexible PCBs comprise three or more layers. Each layer is separated by an insulating material. All the layers are connected with the help of plated through holes (PTH). Connections are featured on all layers of the boards. These PCBs feature high-density connections and are used in critical applications.Multilayer flexible PCBs are used in specific applications that require high number of connections. In today’s technologically advanced era, multilayer flexible PCBs are used in nearly all electronic products and systems. With the advent of PCBs, the possibilities of application design and manufacturing are immense. With flexibility and multiple layers added to the equation, the creativity of the designer is limitless.FPC manufacturers website:http://www.foundpcb.com/flex-pcb/
