As we all know, Huawei has officially launched the Honor 7C smartphone. Today, we will begin to take apart the phone to explore its internal structure.
First, remove the SIM card tray. The SIM card tray can support both dual SIM cards and memory card expansion at the same time. This is undoubtedly good news for users who prefer to use a memory card.
Use a screwdriver to remove the two screws at the bottom of the phone.
After removing the screws, use a pry bar to separate the back cover from the phone body. We found that the fingerprint module is fixed on the motherboard, so there is no need to worry about damaging the connecting cables during the back cover removal process.
The back cover of the phone adopts a three-segment design. The top part is made of metal, while the rest is made using injection molding to ensure good signal transmission performance.
After removing the back cover, we can see the internal structure of the phone. Before removing the fingerprint scanner module, it is necessary to remove the metal cover plate securing the fingerprint module connector. Use a plastic pry tool to disconnect the fingerprint module ribbon cable and remove the fingerprint module.
After removing the fingerprint scan button, we need to disconnect all connections, including the battery, camera, RF antenna, and other components. Its mainboard features a specialized design, which we will explain in detail later. The RF antenna is secured very firmly. The dual rear cameras are held in place by a separate metal plate.
After disconnecting all connections, the motherboard cannot be removed directly. The screws need to be removed first, and then the loudspeaker can be taken out. This phone uses a traditional micro USB port, which is secured by screws on both sides. We need to remove the micro USB port.
After removing the loudspeaker, we understand why the motherboard can not be removed directly. The phone uses a U-shaped motherboard, which means that its motherboard and vice board are designed as a whole part. That is why we say that the motherboard has a special design. As a matter of fact, most smartphones adopt a three-stage design: the motherboard on the top, the battery in the middle, and the vice board at the bottom. In addition, its motherboard and vice board are connected via FPC, which is hidden under the battery.
The advantage of the U-shaped motherboard design is that it occupies more space, which not only provides more ample layout space but also saves costs on flexible printed circuits. However, he motherboard also makes the battery occupy less space. This phone comes with a 3000mAh battery. There is no other component on the middle part of the motherboard.
The other components on the front of the motherboard are all covered with metal shields, except for the fingerprint scanner, which is unprotected. The large SIM card slot takes up a significant amount of internal space on the back of the motherboard. We can also see the Qualcomm Snapdragon 450 processor and Hynix memory chips.
After removing the motherboard, we found that it was mounted within a metal roll cage to prevent displacement.
Summary
In general, the Huawei Honor 7C has both highlights and weaknesses. Whether it is suitable for users depends on individual needs.
