In today's 5G era, small-screen phones seem to have become the past. Nowadays, I still adhere to the small screen is not much, except for the iPhone SE 2 released for some time, it is necessary to count Huawei P40, but P40 is called "castration" flagship. Today, let's take a look at Huawei P40 can you remove surprises?
Dismantle
Take out the calorker, the rear cover is fixed by large-area glue, and the heat shield is used to heat the gap, and the binding tab can slowly open the back cover.
Carto has a silicone ring for a certain waterproof and dustproof effect. The main board position is attached to the protective effect of the bubble.
Remove the back camera cover, the camera cover is fixed by the rear camera. The inner side has a buffered buffer protection.
The main sub-plate cover is fixed by a screw, and the large-area graphite sheet covers a heat dissipation in the battery position, and the main board corresponds to the protective effect of the bubble BTB interface position.
The flash & sensor soft plate and the NFC coil are fixed by a glue and removed in turn. Set of white silica gels for protection.
Disconnect the cable on the motherboard and remove the front and rear camera and the L-plate. Remove the speakers, panels, and USB interface soft boards.
A graphite sheet is subjected to heat dissipation and protective effect on the front camera module. The internal support corresponds to the main board processor position with heat dissipation silicone for heat dissipation.
8 million pixel telephoto camera, model Omni Vision Ov08a10, 50 million pixel main camera, model is Sony IMX700; 16 million pixel wide angle cameras, models are Sony IMX481.
Front 32 megapixel camera, model is Sony IMX616; reddia deep camera, model is Sony IMX332.
The battery is supported by plastic tape and is attached to a lifting handle, and the fixed adhesive paper is very high, and a large force can be separated.
The P40 uses the screen vocalization component to replace the handset, and is supported by the screws. The fingerprint recognition sensor is located between the screen and the inner support, and the separation screen can be removed. Remove the sensor soft board, vibrator, buttons, etc., etc.
Heat the heating screen, softens the fixed screen and the inner support, separated by both. Remove the fingerprint recognition sensor.
The screen is a 6.1-inch 2340x1080 resolution OLED full screen, the model is BOE BF061YQM. The L-liquid cold tube is located on the right side, and the area is not too large.
Looking back, Huawei P40 uses three sections. The rear cover is very secure, and the battery and the screen are fixed. The P40 also once again used the screen vocalization component to replace the handset. The inside is heat dissipated by graphite sheet + heat dissipation silicone + liquid cold copper tube. A large-area graphite sheet is also attached to the battery position for heat dissipation.
Everyone thinks that everyone is considered to be castrated, and whether there is "castration" in the IC?
