Xiaomi CC9 inductor L0439
First time like this problem posted in social media. Great
:)
Your idea sharing is really motivating. Thanks a lot. Sometimes the video seems to be blurry and vision of the writing difficult to see clearly. Thanks again I really appreciate.
Really you guys are sharing the master ideas for better understanding 👏 👍 👌
Once again a big big thank you for your great effort.
Thank you!
Good job sir
please more videos like this......
Thanks a lot for your another great video. Please answer these questions:
1.What temperature did you use to remove the metal cover ( at 2:25)
2. Does that Xiaomi has glued CPU or not?
3. How did you know that you must start measuring in BAND 7 channel and not in different BAND? Thank you again for excellent video.
1. 390℃, wind power 60
2. Xiaomi CPU is almost the same as the other Android phones
3. The L0349 is abnormal since its one end has no value, while L0349 an inductor on BAND7 transmitting channel.
@@CINOTechnology Thanks for your reply.
2. I meant that if the CPU is glued a man must be very careful when desoldering around. Was that Xiaomi with glued CPU? Or not?
3. You tested BAND 7 path. BAND 7 path has 2600 Mhz frequency but Wi-Fi has about 2400Mhz frequency. Does it mean that BAND 7 consists also 2400Mhz frequency? Or am I wrong? Thanks
@@ladbla1752 2. Xiaomi CPU is not glued, and the reverse side of RF is not CPU, so on this video, no need to worry about that
3. RF band is modulated by Baseband, while the Wi-Fi band is modulated by the Wi-Fi chip, so there is no connection between them. For frequency, BAND 7 band ranges from 2500MHz~2570MHz while the Wi-Fi band is 2400MHz, still, no connection.
Thank you for your insightful question :)
