On October 10, 2019, OPPO held a “Super Games Conference” conference in Chengdu, officially releasing the new Reno series products Reno Ace and K series new product OPPO K5. Among them, OPPO Reno Ace has achieved all-round breakthroughs in charging, screen, and configuration. The high-performance configuration combination brings super players an excellent black technology experience. Especially in terms of charging, it supports 65W SuperVOOC super flash charging. The official claim is that it can be fully charged in 30 minutes. At the same time, OPPO Reno Ace is also the world ’s first mobile phone equipped with a standard gallium nitride fast charge charger. It is also thanks to the blessing of gallium nitride technology. Although its original charger has an output power of 65W, it is similar to a conventional charger. Compared with this, it has obvious volume advantages and efficiency advantages. The following charging head net will bring you the internal disassembly of this charger.
OPPO this gallium nitride fast charge charger uses a pure white appearance, rounded body, the surface is brightly treated with piano paint, and the word “SUPER VOOC” is printed on the front.
This charger is equipped with national standard pins and fixed design.The specifications of the product are printed on the side of the pins.
In addition to the OPPO logo on the pin side, you can also see the CCC certification logo.This charger supports 100-240V ~ 50 / 60Hz 1.6A input and supports 5V / 2A or 10V / 6.5A output. The product model is VCA7GACH, which is manufactured by Lite-On Technology Co., Ltd.
The net weight of the charger is about 113g, which is very important in terms of product volume.
Use the latest firmware version ChargerLAB POWER-Z KT001 to test the protocol of the OPPO charger, and show that it supports USB DCP, VOOC, SuperVOOC protocols.
Compared with Apple’s 61W charging volume, OPPO’s 65W charger has obvious advantages, which is also due to the use of gallium nitride technology.
Open the case of the charger, you can see that a gray foam is attached to the inside of the case, which plays a supporting and buffering role.
As can be seen from the front of the PCBA, the layout of the components is very compact.A large number of glue injection treatments are used in the gap and fixed into a whole to enhance the stability and thermal conductivity of the components.
A large plastic insulation board is used on the back of the PCB, and a metal heat sink is attached to the outer layer.
The AC pin is connected to the PCB board through two wires, and the solder joint at the end of the pin is treated with glue to play a role of fixing and insulation.
The input end of the charger uses two electrolytic capacitors for filtering. The outer layer of the larger capacitor is wrapped with 3M tape; the right side of the transformer is stacked with heat-dissipating silicone.
Charging head network disassembly summary
OPPO this 65W original gallium nitride fast charge charger is manufactured by Lite-On Technology Co., Ltd. The product has a round appearance and a compact size. Supports a maximum of 65W output, and has two gears of 5V / 2A, 10V / 6.5A, backward compatible with SuperVOOC, VOOC and other protocols, suitable for the needs of all fast charging mobile phones in the OPPO family. The charging head network learned through dismantling that this charger mainly uses PI customized PowiGaN main control chip, which has the characteristics of high efficiency and high frequency, which greatly reduces the size and heating of the charger; the protocol still uses SwissChip Micro customized VOOC flash charge chip. There is an isolation design between the primary and secondary inside the charger, and an insulation baffle is installed; a large amount of glue injection processing is used between the components to fix the components and assist the heat conduction. The entire product, from materials to workmanship, reveals OPPO’s high requirements for product quality.
