Advantages and disadvantages of FPC wiring
Using FPC can greatly reduce the sizeElectronicsThe volume and weight of the product are suitable for the development of electronic products towards high density, miniaturization, and high reliability. Therefore, FPC is used in aerospace, military, mobile communications, laptopscomputerPeripherals, PDAs, digital cameras, and other fields or products have been widely used. In addition, it can be arranged arbitrarily according to spatial layout requirements, and can move and expand freely in three-dimensional space, thus achievingcomponents and partsIntegration of assembly and wire connection.
In the process of producing products, cost should be the most important consideration. Due to the fact that flexible FPCs are designed and manufactured for special applications, the initial cost of circuit design, wiring, and photographic substrates is relatively high. Unless there is a special need to apply soft FPCWhen applied in small quantities, it is best not to use it. In addition, since a lot of effort has been invested in it, maintenance in the later stage is also essential, so soldering and rework require trained personnel to operate.
FPCCable layingThe storage is different from other products,FPC flexible circuit board should not come into contact with air and water. Firstly, the vacuum of the FPC flexible circuit board should not be damaged. When packing, a layer of bubble film should be wrapped around the edge of the box. The bubble film has good water absorption, which plays a good role in moisture prevention. Of course, moisture-proof beads are also essential.
Secondly, after sealing the box, it must be stored in a dry and ventilated place with a partition wall and off the ground, and avoid direct sunlight exposure. It is best to control the temperature of the warehouse at 23 ± 3 ℃ and 55 ± 10% RH. Under these conditions, PCB boards with surface treatments such as gold plating, electroplating, tin spraying, and silver plating can generally be stored for 6 months, while PCB boards with surface treatments such as silver plating, tin plating, and OSP can generally be stored for 3 months.
