Flexible circuit board, also known as "flexible board", is a printed circuit made of flexible insulating substrate. flexible circuits provide excellent electrICal performance, can meet the design requirements of SMAller and higher density installations, and can also help reduce assembly processes and enhance reliability. Flexible circuit board is the only solution to meet the requirements of miniaturization and mobility of electronic products. It can bend, wind and fold freely, can withstand millions of times of dynamic bending without damaging the wire, can be arranged arbitrarily according to the spatial layout requirements, and can move and expand freely in three-dimensional space, so as to achieve the integration of component assembly and wire connection; Flexible circuit board 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.


flexible printed circuit board


FPC, also known as flexible circuit board and flexible board, is characterized by high wiring density, light weight and thin thickness. It is an excellent flexible printed circuit board with high reliability. FPC can be divided into FPC antenna, FPC touch screen, FPC capacitive screen, etc. according to functions; FPC flat cable is one of them. Generally speaking, the flexible plate flat cable is a connection wire group that can be bent to a certain extent. Here is a detailed explanation of FPC cabling and its use:


1、 Function and purpose of FPC flat cable

FPC flat cable is used to connect two related parts or products. FPC cables are used in many products, such as printers, mobile phones, laptops, etc.


2、 FPC flat cable composition and parameters

The composition of FPC flat cable is the same as that of FPC. FPC flat cable is generally long, with both ends designed as pluggable needles, which can be directly connected with connectors or welded to products. The base material is generally calendered copper, which is resistant to twists and turns and flexible.

Layout parameters: the minimum line width and line spacing are 3mil; The minimum wire hole finished product reaches 0.15 mm.


3、 FPC cable laying process

The surface treatment process used for FPC cable laying is generally gold deposition process; In addition, there are processes such as tin plating and tin spraying.


4、 Advantages and disadvantages of FPC flat cable

1. Advantages:

(1) It can greatly reduce the volume and weight of electronic products and is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability.


(2) It has been widely used in aerOSPace, military, mobile communication, laptop, computer peripherals, PDA, digital CAMeras and other fields or products.


(3) It can also be arranged arbitrarily according to the spatial layout requirements, and can move and expand freely in three-dimensional space, so as to achieve the integration of component assembly and wire connection.


2. Disadvantages:

(1) Because FPC is designed and manufactured for special applications, the cost is high.

(2) Generally, it is better not to use it in small amount.

(3) Later maintenance is essential. Soldering and rework require trained personnel.


5、 Storage of FPC flat cable

First of all, the vacuum of FPC soft board cannot be damaged. When packing, a layer of bubble film needs to be surrounded on the side of the box. Of course, moisture-proof beads are also necessary.


Secondly, after the box is sealed, the box must be stored in a dry and ventilated place separated from the wall and off the ground, and also avoid sunlight.

The above is the flexible board cable and its use. The Circuit board factory hopes to help you. Circuit board manufacturing, circuit board design, PCBA processing manufacturers will explain the flexible board cabling and its use in detail
