Structure made of FPC

Structure made of FPC laminated by Darlox Electronic Limited The domestic quality inspection of FlexiblePrinted Circuit, or FPC, still relies primarily on manual visual inspection, is expensive, and is inefficient. However, FPC is favored due to its light weight, thin thickness, freedom of bending and folding, and other excellent characteristics. Circuit board design is becoming increasingly high-precision and high-density as a result of the electronics industry’s rapid growth. The demands of production can no longer be met by using manual inspection techniques. Automatic FPC defect detection is now a natural progression in industrial development. In purchaser electronic items with versatile designs (like side-sliding cell phones), to guarantee that the item slides in excess of multiple times in the bowed express, a solitary layer FPC (adaptable circuit load up) is typically used to electrically interface two unique modules . The operating frequencies and transmission rates of smart phones are increasing with their development. The differential pair signal must correspond to a layer Reference plane when using MIPI, MDDI, and other interface protocols because the impedance of the differential pair wiring needs to be controlled within a certain range. The current technology typically requires an additional layer or two of copper foil as the reference plane for FPC design, which will double the price. In the same way, adding more layers of copper foil will make the FPC thicker and lead to slippage. The performance suffers greatly, and the product’s lifespan is shortened by decreasing the number of times it uses FPC slides. Product performance will suffer if the sliding area is not impedance controlled. Edit basic structure Copper Sheet Electrolytic copper and rolled copper are the two main categories of copper foil. The typical thicknesses are 1 oz, 1/2 oz, and 1/3 oz. Substrate film: 1 mil and 1/2 mil are the two most common thicknesses. Adhesive (glue): The thickness is determined by the requirements of the client. Cover Movie Protective film for the cover: used for surface insulation. Normal thicknesses are 1mil and 1/2mil. Adhesive (glue): The thickness is determined by the requirements of the client.
