Love to play computer games On July 30, it was reported that at 7:30 this evening, the Xiaomi 8 Discovery Edition will be sold for the first time in the Xiaomi Mall. The biggest highlight of the machine's appearance is the transparent rear cover. However, it was reported earlier that there was an ordinary sticker under the back cover, that is to say, what we saw was not the real motherboard.

At noon today, Zang Zhiyuan, the marketing director of Xiaomi's mobile phone products, revealed the secret of the back of the new machine in a microblog. According to Zang Zhiyuan, the area seen below the back cover of Xiaomi 8 transparent exploration version is a "decorative motherboard", which covers the real motherboard. Officially, it is another "motherboard" with complete circuit board process and decorative significance.

It is reported that the base plate of this "decorative main board" is all copper with steel plate reinforcement. It has 101 capacitors, 32 resistors, 6 switch ICs, 11 sensor ICs and 7 signal control ICs.

In terms of technology, the manufacturing of a "decorative motherboard" will go through four main steps: motherboard circuit imaging, DES precision engraving circuit, motherboard shape refinement, and SMT component assembly, with a total of 45 production processes.

From the official introduction, we can know that Xiaomi spent a certain cost to make a decorative motherboard. Compared with stickers, it has more weight. Although it is much more refined, it also occupies a certain amount of internal space. The shrinkage of the Xiaomi 8 exploration version battery should have a lot to do with this fake motherboard. We may understand that "decorating the motherboard" is an advanced sticker.
