PCB Technical - FPC battery and FPC application in wearable devices

1. FPC batteries in future wearable devices

With the development of technology, wearable devices have been heated up.

It is understood that a company is producing a new type of bendable lithium battery. This bendable FPC battery may be used in wearable devices or bendable smartphones in the future.

According to the company, although the FPC battery is still in the early stages of production, this battery has been tested to maintain power supply capacity under bending and other deformations, while ordinary lithium batteries used in smartphones and other wearable devices will be deformed. Degradation, which will shorten the power supply time.

This FPC battery made its debut at the annual advanced technology exhibition (CEATEC) earlier this month.

Once a lithium battery fails, it will be very unstable. The fact is such an example. Being plagued by battery problems, the phone becomes overheated and may explode. The battery in question will catch fire after being overcharged because the lithium battery can easily accumulate at one point and then become metallic lithium and precipitate.

Once this happens, the heat generated after overcharging can cause the formation of oxygen bubbles, which can easily react with metallic lithium. Once the reaction occurs, it will explode.

According to the company, the flexible FPC battery developed by the company has a multilayer internal and external structure, which makes it very difficult for the battery to leak and overheat. With this new housing and internal structure, FPC batteries are not only safer and more reliable for wearable devices. .

2. Application of flexible circuit board in NFC Bluetooth

Nowadays, flexible circuit boards are increasingly coming into our lives. Here is a brief talk about the application of flexible circuit boards in NFC Bluetooth:

The application of NFC technology is very extensive, with basic functions such as from data transmission to mobile payment, etc. The application of NFC technology is currently in the development period, and its fields include cities, transportation, logistics, security, home furnishing, cities and other large-scale fields, which can be involved in the future The application range of NFC technology will be unpredictable.

Bluetooth (bluetooth) is a radio technology that supports short-distance communication between devices. The Bluetooth configuration is simple. Using Bluetooth technology, it can effectively realize non-contact communication between short-distance mobile communication terminal devices. At present, Bluetooth technology is unprecedentedly widely used. . However, Bluetooth has some shortcomings. For example, it takes 6 seconds for Bluetooth pairing and connection, and pairing requires setting a password. The biggest feature of the information age is more convenient and fast information dissemination. This problem lags behind the use of Bluetooth in real life.

Based on NFC technology, a variety of application products can be developed. The NFC antenna in the Bluetooth-NFC quick pairing module is mainly composed of flexible circuit board coils, functional chips, and rectifier circuits. Through the preliminary drawing design, material selection and test analysis, the flexible printed circuit board manufacturing process is adopted, and the quality of the production process is consistent. Performance control to realize high-frequency, stable, reliable, low-power environmentally friendly products

Function: with trigger and without trigger function

NFC is used in Bluetooth. Achieve quick matching and connection. It is 1/30 second of traditional application time. Greatly save time and simplify operation. Improve the convenience of users' operation., It has revolutionized the experience of traditional speakers, closer to our lives, and makes the application more convenient. With the popularity of NFC on mobile phones, it will bring users a new way of experience! NFC is expected to become standard on Bluetooth speakers, and it will also become a new trend in the wireless audio market!

The above is the application information of the flexible circuit board produced by the circuit board factory in the NFC Bluetooth.
