Nut R1 is the first wireless charging mobile phone of Smartisan. Officially released two wireless chargers for consumers to purchase. Previously, we dismantled the first wireless charger of Hammer Technology: Nut alarm type wireless charging stand.
Today's unpacking and unpacking is for you to bring the second wireless charger that will be released later: Nutcake-style wireless charging stand. I believe many people are very curious, what is the difference compared with their predecessors? Then the next disassembly, the charging head network will come to you for everyone.
One, nut cake type wireless charging stand out of the box
The front of the package is the outline icon of the wireless charger, and the lower line is the product name: Nutcake type wireless charging stand.
The back of the package is printed with the main parameters of the product. Product Name: Nutcake-type wireless charging stand; Model: WCD30; Input Power: 5V2A / 9V1.1A; Output Power 10W (max); Input Interface: Type-C; Includes: Wireless Charging Block, data cable, manual, three packs of certificates; Size: 99*7.1mm; Weight: 99.5g. Manufacturer: Beijing Hammer Digital Technology Co., Ltd. Manufacturer: Suzhou Lanpei Wireless Communication Technology Co., Ltd.
The interior parts of the packaging are also very particular about the layout. There are humanized small handles in various places. This continues the style of Hammer Technology.
Contents include: Wireless charging station, USB-A to USB-C data cable (length 1m), manual and three packs of voucher.
The manual has a separate page to indicate that this product is compatible with nuts R1, iPhone X, iPhone 8/8 Plus, Samsung S9/S8, Xiaomi MIX 2S and other mainstream mainstream wireless charging phones. Because the nut R1 coil position is slightly biased to the lower left Instead of the common intermediate position, the illustration shows that the bottom left position of the phone is the most efficient.
The front of the nut cake type wireless charging stand is black, and the center position is a wireless launching logo. The panel is made of non-slip PC+TPU material, which prevents the phone from slipping during charging and causing accidental drop.
The back and the main body are black, made of aluminum alloy material, feel comfortable and delicate. Peripheral embedded black rubber anti-slip bar, "C"-shaped half circle more than the entire circle design sense. The middle is the hammer logo, the bottom is mainly Product parameters, Designed by Smartisan is written in the notch position of the rubber strip.
Using USB-C interface, support positive and negative insertion.
Second, nut cake type wireless charging seat dismantling
The wireless charging stand adopts a buckle structure and can be opened without damage by using a crowbar.
A white thermal conductive silicone rubber is coated in the middle to play a role in fixing the heat conduction. The PCB board is semicircularly distributed on the outside of the coil and occupies about half a space.
The middle of the coil is a temperature probe, which can measure temperature directly.
The metal base adopts the CNC integral molding process, and the internal appearance is exquisite. The workmanship is not compromised because the consumers cannot see it.
USB-C female.
The product adopts the American IDT wireless charging scheme, IDT P9237, which is exactly the same as the nut alarm clock type wireless charging stand.
Next to a 4H7520G34BS for storage, used to store IDT P9237 configuration.
Coil joints are plump and wet.
4 X7R capacitors.
Both sides of the capacitor are the MOS of the drive coil, 4 megas VS3618AE.
Remove the four screws and remove the entire PCB board and coil. The back of the PCB board is marked with the product foundry: Lan Pei Technology.
Family portrait, dismantling this end.
Third, the charging head network disassembly summary
If the nut alarm clock type wireless charging stand is the corresponding high-end positioning, it is obvious that the nut pie type wireless charging stand is taking the cost performance route. Compared to the nut alarm clock type wireless charging stand, the nut cake type wireless charging stand adopts the same IDT wireless The charging scheme provides stable performance guarantee for 10W wireless charging.
Due to the price and cost constraints, less than half of the price will be inferior to the alarm clock type in the use of materials and user experience. Fortunately, the workmanship is still exquisite, fully worthy of this price, can be said to want to take advantage of wireless charging features early adopters An ideal choice for users.
