       FPC factory may encounter the problems of FPC overflowing adhesive during the production process.  This problem refers to that during the FPC manufacturing process, the adhesive overflows from the edge or pad of the FPC board, resulting in excess adhesive on the FPC. This problem may negatively affect the performance and reliability of the FPC, so steps need to be taken to address this problem. So how to solve this problem?   1.  Control the amount of  adhesive In the FPC manufacturing process, the amount of  adhesive   should be  properly  controlled to avoid using too much  adhesive . The problem of  adhesive   overflow  can  be reduced by reasonable  adhesive   spraying or roll coating technology.     2.  E venly   d istribute   adhesive The adhesive  should be evenly distributed on the pad and the surface of  the FPC board to avoid excessive adhes...

      FPC  is not only  small and light,  but also  has high performance and functions. As a new welding technology, laser welding is widely used in FPC manufactur ing  by  FPC  factory . So what are the advantages of laser welding FPC?   1.  Laser welding uses high-density, high  heat  laser beams to focus and melt tin solder, while the solder joints of FPC can be directly focused by laser spotlights .   This  is not only conducive to precise control of solder joints, but also to avoid phenomena such as pseudo soldering or false welding.     2. FPC  is not suitable for electrostatic reaction during welding, and the reason why laser welding technology is superior to traditional welding technology is that it uses non-contact welding, which greatly reduces the possibility of static electricity generated by friction  during  FPC welding.     3.  Laser welding  is...

       FPC is a thin, light, flexible circuit board, which is widely used in electronic devices such as mobile phone, laptop and cameras, etc. However, FPC manufacturers sometimes have defective boards in the production process, so what cause the defect? How to solve these defect?       1.  FPC hole have solder mask and patterns have pinholes M ain  R eason: 1) FPC did not print paper in time during screen printing, resulting in too much residual ink accumulated on the screen plate, and then the residual ink would be printed into the hole under the pressure of the scraper. 2) If the screen mesh number is too low, it will also cause solder mask in the hole. 3) There is dirt on the photographic plate, which will cause the part of the FPC that should be exposed during the exposure process   to lose light , resulting in pinholes in the  patterns .     Solution: 1)  The paper should be printed in time and the high-mesh scr...

       Due to cost and technical reasons, FPC sometimes has failure problems during production and application.  In order to find out the cause of the failure and find a solution to the problem, the FPC factory must conduct a failure analysis on the failure case. So how to find out the cause of FPC failure?       First of all, the FPC factory should pass information collection, functional testing, electrical performance testing, and simple visual inspection to determine the failure location and failure mode of the FPC.     Next, it is necessary to analyze the failure mechanism, that is, use various physical and chemical means to analyze the mechanism that leads to FPC failure or defects, such as virtual welding, pollution, mechanical damage, moisture stress, medium corrosion, fatigue damage, stress overload, etc.     Then, the cause of failure analysis is carried out, that is, to find the cause of the failure mechanism.  G...

       In the production of FPC factories, only by ensuring higher quality and more stable use effects can they be recognized by consumers. So what are the methods of FPC Factory quality control?       1. Stable and permanently engineered processes as the basis for production The production of FPC needs to be based on a certain process and a perfect production process.   FPC factory   need a complete design process and precise design scheme   during production .   Before the  scheme   is determined, professionals will conduct all-round discussions to ensure the reliability of the  scheme , and it will not be easily adjusted after the  scheme   is established, so the quality of each product can be guaranteed to be stable.     2. Precise control of the production process The production quality of FPC will be affected by the actual production process. Therefore, when the FPC factory is in pr...

      FPC cable refers to a group of connecting wires that can be bent to a certain extent. Its base material is generally rolled copper, and its function is to connect two related parts or products. So what are the advantages and disadvantages of FPC cables?       Advantages: The use of FPC cables can greatly reduce the volume and weight of electronic products, which is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Therefore, FPC cables have been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDA, digital cameras and other fields or products. In addition, it can be arranged arbitrarily according to the requirements of the spatial layout, and can be moved and expanded arbitrarily in the three-dimensional space, so as to achieve the integration of component assembly and wire connection.     Disadvantages: In the process ...

     Nowadays, various electronic devices are becoming more and more important in our daily lives. All kinds of electronic products need to use circuit boards, so the types of circuit boards are also diverse. Most of these devices will use   flexible PCB , if without it, many electronic devices will not work properly. Different type of PCB have their own advantages. As one of the most common circuit boards, flexible PCB has the following main advantages: 1.  Flexibility Elasticity and bending ability are the main advantages of flexible PCBs, they can be manipulated in various ways to fit the folds and creases of the edges. The flexibility of this circuit board also means that it is more reliable and durable than ordinary PCBs, it can also reduce the impact of vibration, and there are few wiring on the circuit board. Minimal wiring eliminates the needs for interface connections such as solder joints, contact crimping and connectors. 2.  Reduce weight and spa...
