Rapid development of mobile phone wireless charging circuit board

The Circuit board manufacturer, circuit board designer and PCBA manufacturer explain to you why the mobile phone wireless charging circuit board can develop rapidly?

What do modern people fear most when they go out? Some people will say that there is no WiFi, and compared with no WiFi, the thing that Xiaobian thinks is more terrible is: hands! Machine! No! ElectrICity!

Although mobile phones, tablets and other electronic products have brought great convenience to people, the subsequent charging problem has also brought trouble. Different types of charging lines, chargers, and power packs add weight to the bag. If you bring the wrong model, you will be in an awkward situation of "loss of connection".

Evolution history of wireless charging

The charging mode of mobile phones is also evolving with the development of mobile phones. In the early years of the rise of SMArt phones, the charging of mobile phones depended on "universal charging". Now this little thing has disappeared in the long river of history, replaced by USB cable charging, which is also a common way of charging at present. We can call it the charging 2.0 era.

The 3.0 era of charging is just the emerging wireless charging. Using Tesla's electromagnetic induction principle, the current is indirectly transmitted to the battery through induction to complete the charging operation.

Today, let's talk about why mobile wireless charging can develop rapidly?

1、 The giants have joined in wireless charging

According to the small editor of mobile phone wireless charging circuit board, first of all, smart phones fully embrace wireless charging. Half a year after Apple joined the WPC Alliance, it launched three mobile phones with wireless charging function -- iPhone 8/8 plus and iPhone X, which made people sigh. After a long winter, it was finally the spring of wireless charging. Another big man with the right to speak, Samsung, has always been a wireless charging "loyal fans". The flagship S9 series mobile phones launched in 2018 listed wireless charging as an important upgrade. Xiaomi is also the most active mobile phone in China. In March 2018, the flagship of Xiaomi, the MIX2S, was introduced into the wireless charging function for the first time, followed by Huawei, making the wireless charging MARKet more lively.

2、 5G era is coming

The second is the promotion of the coming 5G network. A large number of RF modules have been added to the 5G mobile phone. With the increasing requirements of thinness and lightness, the existing space utilization has reached the limit, so there is no room left for the battery. As we can see, Apple has already taken the lead in canceling the headphone jack, which is not only for personality and fashion, but also an important attempt to make way for the new modules of 5G mobile phones. Within the 5G technical framework, it is a process of mutual compromise to promote the popularization of mobile phone wireless charging technology.

3、 Rapid improvement of mobile phone hardware

According to the small editor of mobile phone wireless charging circuit board, the lack of major breakthrough in battery technology also forces the further development of wireless charging technology. The improvement of mobile phone hardware performance can bring us a better experience, and in some places it has exceeded the impact of intelligent terminals such as computers. However, with the rapid improvement of mobile phone hardware, power consumption is becoming more and more fierce. Mobile phone battery technology does not seem to keep pace with the rapid development of hardware. As a portable mobile phone, no electricity is equivalent to a brick. At this stage, how to improve the charging experience has become a top priority, which is also the original power of the rapid rise of wireless charging.

4、 Market demand

Of course, the most important is the consumer experience appeal. Although some people hold the view that wireless charging is "cool, but not practical". However, from most user experiences, wireless charging is not only interesting, but also practical. Whenever you use your phone, just put it on the charging tray to charge it. Compared with wireless charging, the process of finding a USB charging connector on a messy desk, then plugging it into the USB interface and putting down the phone is as complex as acrobatics.

Wireless charging has ushered in explosive growth, and now it is the golden development period of wireless charging. When users get used to wireless charging technology, wireless charging will become a necessity for mobile phones like WiFi, completely changing users' charging needs.
