Every time as long as Apple has a new product release, the digital circle will usher in a wide wave of hot discussion. After all, Apple, as the world's top technology manufacturer, will always bring us unexpected surprises.
Looking back, this year's iPhone 13 series, whether it is the A15 processor at the time of the conference, ProMotion adaptive 120Hz screen and other technological innovations.
Or in appearance, smaller bangs, consistent simple design, or eye-catching color (macho fans love). It can all show that this is a work of sincerity.
The starting price of the real fragrance makes many fruit powders say that they want to buy and buy. On the day of the pre-sale, the expected result, Apple's official website collapsed, and the e-commerce platform did not grab a lot of people.
And Pinduoduo's sale of a price reduction of 500 is even more the popularity of the iPhone 13 to the peak, have you grabbed it? (I hope that those who grab it will not be cut)
For a time, "did you grab the iPhone 13" and "I changed the phone" became the hottest topics for everyone.
Even today, there is such a dramatic scene: Apple CEO Cook sent such a Mid-Autumn Festival blessing on Weibo:
But everyone doesn't care whether Cook eats mooncakes or not, what kind of filling, but the small tail of this iPhone 12 Pro Max.
Good guys, it turns out Cook you didn't use 13 ah? Netizens even said: Cook did not grab 13, but also cut orders!
For a time netizens all kinds of discussions, Cook is also on the hot search list four, haha, in fact, most of everyone's discussion is just a joke.
Of course, it is not ruled out that Apple deliberately engaged in marketing (but it is not necessary), and whether Weibo is operated by Cook himself is difficult to say, in short, you will also have a good time.
The iPhone 13 is indeed a complete mess, and friends who buy it don't think that everything will be fine, because recently there is such a thing that needs special attention:
Official information from Apple, in the iPhone 13, the antenna is made of recycled plastic water bottles!
Some users directly exploded!! Originally the iPhone signal is poor, now use a plastic antenna, will it really not affect the mobile phone signal?
So, let's take a look.
This is the content of the article from Apple's Newsroom, which mentions the reasons for Apple's commitment to the environment, upgrading plastic water bottles into a more powerful high-performance material to make antennas.
After all, this is Apple's environmental philosophy, and this is the first time the industry has tried this technology. Seeing this, I hope that you will not jump to conclusions because of the word plastic.
First of all, it should be clear that the antenna in the mobile phone does not only refer to a single component, it can include: coaxial signal line, on-board printed antenna, antenna small board, fuselage frame, border antenna band and so on.
Therefore, it is not correct to conclude that the signal is poor just by using plastic.
Taking the frame in the mobile phone that we are most familiar with as an example, in general, the metal frame of the mobile phone will affect a certain signal, so almost all the mobile phones you see will have sky line bands.
The antenna strip is generally made of plastic material, the purpose of which is to reduce the electromagnetic shielding effect generated by the all-metal frame, so that the mobile phone can have a better signal.
This also explains why phones with metal backshells are now almost gone.
At the same time, in addition to adding a plastic antenna band to the metal frame, you can also add a metal small A-shell antenna on the side like the MIX4.
The actual effect is like this:
Because it uses the Unibody all-ceramic process, adding a metal antenna to the screen bracket can concentrate on increasing the strength of the signal.
Therefore, as an important part of the mobile phone signal antenna, the plastic antenna strip is completely reasonable.
Inside the mobile phone disassembly, the use of plastic is also a routine operation in the on-board printed antenna and antenna platelet.
As recognized by The Fruit, the LDS process, namely: laser direct molding technology, has long been widely used in mobile phone on-board circuits, antennas and other fields.
Among them, the LDS material is a plastic with a metal composite, and after the moving laser irradiates the material, it can be laserd to form the desired antenna circuit.
These antennas made using LDS technology are an important component of the miniature antennas of today's communication equipment, which supports the development of mobile communications.
Apple's use of Intel's baseband in the early years caused serious problems with mobile phone signals, so it was branded with poor iPhone signal.
In the era of 5G networks, signal capabilities are particularly critical, and Apple has also used a high-pass baseband with better RF signals, and the hat of poor signals has gradually been removed.
So, taken as a whole: the antenna in a mobile phone is more than just a simple ordinary circuit board.
The plastic in Apple's mouth is not the plastic in the public user perception, and it may have a higher technical content.
The quality of the signal, many times is not the problem of the mobile phone, the region, coverage, interference and a series of conditions are factors that need to be considered.
What's more, Apple wouldn't be stupid enough to give up mobile phone signals for the sake of environmental protection, right?
