E dismantling: Nokia Return, C3 with removable batteries

"Why not invent a detachable battery?" 10 after this soul is tortured whether you don't know how to explain? Today, NOKIA's latest C3, a mobile phone that is removably disassembled, is dismantled by ewistech. Today, I returned to that year with a backing battery instead of charging treasure. Dismantlement step The rear cover is adopted by detachable design, and the rear cover is opened by a buckle of the bottom, and a graphite sheet is posted on the back cover. The side push key is fixed to the back cover by the riveting process. The rear end cover is fixed by a screw, one of which has a tamper tag. Since C3 uses detachable rear cover design, fingerprint recognition is fixed under the rear end cover, which avoids damage to the fingerprint identification module when dismantling the rear cover. 3 FPC antenna integrates on the rear end cover. Do you have never seen this battery port for a long time? Waterproof stickers are also posted on the battery port. Replaceable batteries, battery capacity is 3040mAh, and a waterproof label is posted on the battery. The motherboard and the sub-plate are fixed by a screw, and the front camera is fixed to the motherboard by a conductive tape. The fingerprint recognition soft board is attached to an insulating tape. 8 megapixel rear camera, F2.0 aperture. 5 megapixel front camera, F2.4 aperture. The main panel is connected to the soft board, the handset, the vibrator, and the distance sensor soft plate and the side key soft plate are supported by the glue. The button soft board is posted on a black protection tape. Finally, it is heated, separated by heating table, separating the screen and the inner support, and the inner support is attached to the motherboard. Perhaps due to factors, the screen is selected from the LCD screen of the 5.99-inch 1440x720 resolution. Motherboard IC information: The motherboard shield CPU and the memory location are attached to the thermally conductive silicone. The main IC of the motherboard (below): 1: UNISOC - SC9863A - Tiger Balph Nuclear Processor 2: ISOCOM - MDXC1024G - M3 3GB memory chip 3: Unisoc - SC ***** - Power Management 4: UNISOC - SR ***** - RF transceiver chip 5: Accelerometer? The main IC on the back of the motherboard (below): 1: ISOCOM - MEMA032G - 32GB flash chip 2: RF power amplifier Summary information The whole machine is designed to use 23 screws to fix, except for screen and fingerprint recognition, and the first design of the first Nokia smartphone is basically the same. Most of the chips used are domestic chips. The heat dissipation is also the most basic graphite and thermally conductive silicone heat. Removable cover + replaceable battery design + integrated FPC antenna plastic rear end cover design, makes disassembly and maintenance easier, and cost is relatively low.
