Due to the large number of pin pins in the power supply, the standard can reach up to 24 pins (additional spare pin pins arranged by the structural designer). Other styles use single row 24P patches, which is not very practical considering the main size of the type-c mother seat. Therefore, at the beginning of the type-c mother seat design, the default pin is to use double row pin SMT patches for PCBA welding processing. After mass production of the dual pin type-c mother seat, Due to its high requirements for production process and SMT accuracy, with the increase of usage, the dual mount type gradually shows some structural deficiencies. The first and foremost is that when the product cannot reach a one-time good product offline, the inspection and maintenance of the end type-c mother seat interface is very difficult. For example, when there are problems such as false soldering, false soldering, and tin sticking in the chip pins, the inner 12Pin pin pin pin cannot be directly inspected, The entire interface needs to be removed as a whole, and the use of front plug back mount packaging specifications can effectively improve and solve the shortcomings of such structures. Production line quality inspectors or maintenance personnel only need to inspect and repair the interface soldering situation of relevant PCBA products by detecting the solder pins under the board and SMT chip pins at the end of the interface.

Improvement of USB 3.1 type-c current output: It is said that compared to the USB type-a interface, the current output voltage of the USB type-a interface is 5 volts. In the newly released MacBook, we can also know that the charging interface can be increased to a maximum of 20 volts, which not only accelerates charging time, but also plays a significant role in subsequent power supply needs.
