Deep disassembly of oppo Reno ace original 65W Gan charger
On October 10, 2019, oppo held a "super play conference" in Chengdu, officially releasing Reno ace and oppo K5. Among them, oppo Reno ace has achieved all-round breakthroughs in charging, screen, configuration, etc., and the combination of high-performance configuration brings super players excellent black technology experience. Especially in the aspect of charging, it supports 65W supervooc super flash charging, and officially claims that it only takes 30 minutes to charge.
At the same time, oppo Reno ace is the world's first mobile phone equipped with gallium nitride fast charging charger, which benefits from the blessing of gallium nitride technology. Although its original charger has 65W output power, it has obvious advantages in volume and efficiency compared with conventional chargers. The following charging head network will bring you the internal disassembly of this charger.
1、 Appearance of oppo 65W Gan fast charging charger
Oppo's Gan fast charging charger has a pure white appearance with a round body. The surface is polished with piano baking paint, and the words "super vooc" are printed on the front.
This charger is equipped with GB pin, fixed design. The specifications of the product are printed on the pin side.
Besides the logo of oppo, the CCC certification mark can also be seen on the pin side. This charging device supports 100-240V ~ 50 / 60Hz 1.6A input and 5V / 2A or 10V / 6.5A output. The product model is vca7gach, manufactured by Guangbao Technology Co., Ltd.
The usb-a output interface adopts yellow rubber core.
The net weight of the charger is about 113g. Compared with the volume of the product, this weight is very important in hand.
Use the latest firmware version of chargerlab power-z kt001 to test the protocol of oppo charger. It shows that it supports USB DCP, vooc and supervooc protocols.
Compared with apple 61W charger, oppo 65W charger has obvious advantages, which is also due to the adoption of Gan technology.
2、 Disassembly of oppo 65W Gan fast charging charger
Open the charger shell, you can see that there is a gray foam on the inner side of the shell, which plays a supporting and buffering role.
It can be seen from the front of PCBA that the layout of components is very compact. In order to enhance the stability and thermal conductivity of the components, a large amount of glue injection treatment is used in the gap to fix it as a whole.
A large plastic insulating board is used on the back of PCB board, and a metal heat sink is pasted on the outer layer.
AC pin is connected with PCB through two wires, and glue injection treatment is used at the solder joint of pin end to play the role of fixation and insulation. The input end of the charger is filtered by two electrolytic capacitors, and the outer layer of the larger capacitor is wrapped with 3M tape; The right side of the transformer is covered with silicone. The output terminal adopts customized usb-a interface, and the left side is two output filter electrolytic capacitors; On the right side are two series Y capacitors, which are used to output anti-interference.

Simply clean the silica gel on the front of PCB board.
Summary of dismantling charging head net
Oppo's 65W original Gan fast charging charger is manufactured by Guangbao Technology Co., Ltd. It has a round appearance and small size. It supports a maximum output of 65W, and has two gears of 5V / 2a and 10V / 6.5A. It is downward compatible with supervooc, vooc and other protocols. It is suitable for all the fast charging mobile phones in oppo family.
Through the disassembly of the charging head network, we learned that this charger mainly uses the powigan master chip customized by pi, which has the characteristics of high efficiency and high frequency, greatly reducing the volume and heating of the charger; In terms of protocol, Ruixin micro customized vooc flash charging chip is still used. There is isolation design between primary and secondary in the charger, and an insulating baffle is installed; A large amount of glue injection treatment is used between components for fixing components and auxiliary heat conduction. From materials to workmanship, the whole product reveals oppo's high requirements for product quality.
