FPCB Purpose and method of use

The FPC cable is defined on website as a connecting wire group that can be bent to a certain extent. Its base material is generally made of rolled copper, which is resistant to tortuous and flexible. At the same time, it is also a functional form of fpc. Having said that, the next content is to explain what are the advantages and disadvantages of fpc.

FPCB Advantage

Let me talk about its advantages first. The use of FPC can greatly reduce the volume and weight of electronic product s, and is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Therefore,

FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDAs, digital cameras and other fields or products. In addition, it can be arbitrarily arranged in accordance with the space layout requirements, and can move and expand in three-dimensional space, so as to achieve the integration of component assembly and wire connection.

shortcoming

In the process of producing products, cost should be the most considered issue. Since the flexible fpc is designed and manufactured for special applications, the initial circuit design, wiring and photographic masters require higher costs. Unless there is a special need to apply soft fpc, it is usually best not to use it in a small amount of application. In addition, since a lot of energy has been invested in doing it, post-maintenance is naturally essential, so soldering and rework need to be operated by trained personnel.

How to store FPC cables

Unlike other products, FPC flexible circuit board s are actually not in contact with air and water. So how should we store this product correctly? I believe everyone will find the answer after reading the following content.

First of all, the vacuum of the FPC flexible circuit board cannot be damaged. When packing, a bubble film needs to be placed on the side of the box. The bubble film has better water absorption, which plays a good role in moisture prevention. Of course, moisture-proof beads are also indispensable. of.

Secondly, after sealing, the box must be stored in a dry and ventilated place with partition walls and off the ground, and avoid sunlight. The temperature of the warehouse is best controlled at 23±3 degree Celsius, 55±10%RH. Under such conditions, PCB boards with surface treatments such as immersion gold, electro-gold, spray tin, and silver plating can generally be stored for 6 months. Surface-treated PCB boards such as Shen tin and OSP can generally be stored for 3 months.

After the final finished product inspection, FPC flexible circuit boards can be vacuum packaged and stored for shipment. So why do flexible circuit boards need to be vacuum packed? How to store after vacuum packaging? How long is its shelf life? I believe that after reading the above content, everyone will have a clearer answer

The above are the advantages and disadvantages of FPC cables. It is easy to understand the advantages and disadvantages of storing FPC cables.
