          FPC has the advantages of thin, light, and flexible, and can be flexibly routed in complex or restricted spaces.  During the production of FPC factor y ,  coverlay  are sometimes opened on the FPC.  What is FPC coverlay opening?   Why does  FPC need to open coverlay.    1.  What is FPC Coverlay Opening FPC coverlay opening refer to coating a protective film on the FPC, and then opening the film layer through cutting or etching technology to expose part of the circuit that needs to be exposed.  This can protect the FPC while ensuring that the required circuits can work properly.      2.  Why dose FPC need to Open Coverlay 1)  Circuit connection FPC is often used to connect different parts of electronic devices or systems.  The coverlay openning process exposes the circuitry beneath the coverlay for physical and electrical connections to other circuits, components or con...

          With the rapid development of vehicle electrification, intelligence, and comfort, in-cabin NVH (Noise, Vibration, and Harshness) performance has become a key indicator of overall vehicle quality. In particular, for new energy vehicles, the significant reduction of engine noise makes wind noise, road noise, and high-frequency tonal noise from electric drive systems more noticeable. As a result, traditional passive sound insulation methods are increasingly insufficient to meet the rising expectations for cabin comfort. Against this backdrop, automotive Active Noise Control (ANC) systems have emerged as an effective solution. As a professional automotive PCB manufacturer, HoYoGo provides reliable PCB  platform s  for ANC   mixed-signal  chains   and real-time algorithm processing , enabling   low-noise  performance , strong immunity to interference, and long-term reliable operation ,  helping vehicles maintain ...

          Whatever it is a 3 layer flexible copper clad laminate or 2   layer flexible copper clad laminate, there are three main manufacturing technologies. Each FCCL manufacturer will adopt different technologies according to its own characteristics. Do you know what manufacturing technologies are used in flexible copper clad laminates?     1.  Coating Method The coating method is a copper foil coated with adhesive,  uniformly  coated the   prepolymer of liquid polyimide resin , such as the copper foil of the 2 layer flexible copper clad laminate without an adhesive layer, and then pass it through the adhesive layer , and then through heating and drying, the coating resin   is imidized t o form a polyimide resin film.   For 2 layer flexible copper clad laminates, generally in order to improve the higher adhesion between the resin layer and the copper foil, some technologies first coat a layer of high-adhesion p...
