Function and use of Zhongshan FPC wiring and advantages and disadvantages

What is FPC wiring

Speaking of FPC wiring, you must understand or familiar with the FPC wiring board is what? FPC wiring plate can be divided into many kinds according to the function, such as FPC antenna, FPC touch screen, FPC capacitive screen, etc. FPC wiring plate is one of them. Generally speaking, FPC wiring plate is the connection line group that can be bent in a certain degree.

Two, FPC wiring function and purpose

The function of FPC wiring is to connect two related parts or products. Now, many products are used to line, because it has a certain flexibility, in the printer, mobile phone, notebook and many other products have used FPC line. FPC line manufacturers are mainly concentrated in the Pearl River Delta region, which is headed by Shenzhen.

3. Composition and parameters of FPC wiring

FPC wiring is a kind of FPC wiring board, so its composition is the same as that of FPC wiring board. The FPC wiring board is usually long and designed to have pluggable needles at both ends. It can be directly connected to the connector or welded to the product. The middle is generally the line, because the FPC line needs a certain flexibility, therefore, the base material is generally calendered copper, tortuous resistance, flexible.

Layout parameters:

The minimum line width line spacing is 3mil/3mil.

Minimum wire hole finished product up to 0.15mm.

FPC wiring process

The surface treatment process used for FPC line is usually gold immersion, and occasionally oxidation prevention. But the anti-oxidation process can not withstand high temperature, the environmental bearing capacity is worse than the gold sink, the two prices are similar, therefore, most of the gold sink process. In addition, there are tin plating and tin spraying process, but FPC temperature is generally below 280 degrees Celsius, and tin spraying will have more than 300 degrees Celsius temperature, and tin paste hardness is smaller, so it is rarely used.

5. Advantages and disadvantages of FPC layout

Advantages:

Using FPC wiring board can greatly reduce the volume and weight of electronic products, suitable for electronic products to high density, miniaturization, high reliability direction development needs. Therefore, FPC layout board has been widely used in aerospace, military, mobile communications, portable computers, computer peripherals, PDA, digital cameras and other fields or products. In addition, it can be arranged according to the spatial layout requirements, and can be moved and expanded in three-dimensional space, thus achieving the integration of component assembly and wire connection.

Disadvantages:

Cost should be the most important consideration in the production process. Since the flexible FPC is designed and manufactured for special applications, the initial circuit design, wiring and photographic plates are expensive. Unless there is a special need to use FPC wiring board, usually in a small number of applications, it is best not to use. In addition, since a lot of effort has been put into doing it, the maintenance of late is also essential, so tin welding and rework need to be trained personnel operation.

FPC line storage

Unlike other products, FPC exhaust boards are not in contact with air and water. So how do we store this product correctly? Believe that read the following content, we will find the answer.

First of all, the vacuum of the FPC wiring board can not be damaged. When packing, a layer of bubble film should be wrapped around the side of the box. The water absorption of the bubble film is better, which plays a very good role in moisture-proof.

Secondly, after sealing the box must be separated from the wall, stored away from the ground in a dry and ventilated place, but also avoid sunlight. The temperature of the warehouse is best controlled at 23±3℃, 55±10%RH. Under such conditions, PCB boards with surface treatment such as gold, electrogold, tin spraying and silver plating can generally be stored for 6 months, and PCB boards with surface treatment such as silver, tin and OSP can generally be stored for 3 months.
