The one that will be dismantled in this issue is the glorious new machine that was just released on Monday - Changwan 7C. Let's just take advantage of the new one and quickly remove it. The conventions are explained at the beginning. This column is to cooperate with the love play player. In cooperation with love and play, it is to cooperate with love and play, and important things are said three times. Some of the angles and shots in the photos do not appear in the video of the lover. Of course, if you want to see the whole dismantling video, Welcome to Koala and listen to him.
Not much to say, this will open up. Before the formal hands-on, of course, Cato should be taken out. Here to say, play the 7C Cato is different from the common and or slot, this slot can be kept double SIM cards and expansion cards are used at the same time. This is good news for students who like to use memory cards.
Then start the formal dismantling, first unscrew the two bottom set screws. Here Tucao screwdriver, often encounter the head model is not enough, a small snack is not too strong, bigger one is too big to In the end, we still used old A to help.
After the screws are resolved, the back cover can be easily separated using the cymbal. In our dismantling, the post-fingerprint identification of the Changwan 7C is actually fixed on the main board. When separating the back cover, there is no need to worry about the cable. This habit of first observing and reprocessing still hopes everyone can develop.
The back cover is obviously a three-stage design. The middle part is metal. The upper and lower ends use an injection molding process to ensure that the signal overflows. On the actual perception, there is a certain color difference between the three sections, but it is not obvious. The patch on the back cover is only In order to ensure a tightly fitting gasket, it does not have the ability to assist heat dissipation like graphite.
After the back cover is removed, the internal structure can be started. First, remove the most prominent fingerprint identification element. The BTB connector of the cable is fixed under the metal fixture. Remove the fixed cover first. To our surprise, the interface actually stuck to the back of the metal cover. When the cover was removed, it was brought down.
After removing the fingerprint identification button, carefully disconnect all connections, including power supply, camera, radio frequency cable, etc. Be careful not to leave it to avoid damage when removing the main board. A clearer part to say again.
What is different from the past is that after the connection on the mainboard was removed, we could not directly remove the mainboard. We need to turn our eyes temporarily to the lower part of the sound chamber, and remove the screws one by one. The entire sound chamber can be directly dismantled. Here we can also see that the 7C used is still a relatively traditional micro USB interface, both sides have screws, do not miss the time of removal.
After unraveling the voice, you can discover why you cannot directly remove the main board: The U-shaped main board, which is now relatively rare, is used on the 7C. In fact, the so-called main board and sub-board are integral. Why is it rare now, because it is now Most mobile phones use a three-stage design. The upper main board, the middle battery, the lower sub board, and the main board and the sub board are connected by an FPC. Some of the FPC are hidden under the battery, and some are directly on the battery surface. Across, this is no need to say more.
The benefits of using U-type motherboards are naturally increased plate area, more layout locations, and the cost of an FPC and two BTB connectors. The disadvantages are, of course, that the middle part squeezes the battery space. The whole machine is only equipped with a 3000mAh battery, which is affected to a certain extent. This is not to say that the special-shaped motherboard is certainly not good. After all, it is recognized that the excellent workmanship and design of the iPhone are very fond of special-shaped motherboards, but play 7C motherboards in the middle There is no component placed on the site, and the connection is simply used. This design is rather strange.
It can be seen that the front of the main board has a separate mask except for the fingerprint identification element. The contents under it are not very much. The first thing to see on the backside is a huge three-card coexistence card slot, which is really crowded out. With less internal space, it may be precisely because of this that most cell phones use non-essential selection slots or slots. In addition, we can also see the Opteron 450 chips with QUALCOMM tagging, and with Hynix. Sign of the package memory particles.
As for the roll cage from the surface cleanliness and gloss and processing traces, it belongs to the ordinary Thousand Yuan machine level, taking into account its price, can be considered a little bit of super level play.
Honestly speaking, Changwan 7C is not a traditional RMB 1000 water bucket machine. It has certain bright spots and many disadvantaged items. To choose a classmate, it is still recommended to consider whether to meet their own needs.
The dismantling of this issue is over here. If you like to disassemble yourself, or if you like to disassemble and understand the internal structure of the machine, you are welcome to continue to pay attention to our iMobile mobile home. We will continue to bring more interesting Dismantling the content. As for the next issue, we'll take a break, so let's wait until the beginning of next issue.
