Chosen Solution
I have an iPhone 6s Plus that i suspected had a logic board problem because both WiFi and cellular connection didn’t, and still doesn’t, work. Anyway, I took the logic board out to check it out and discovered that “this” component (blue) was loose. And eventually after I it fell off. I don’t know what this component is called, but since I have a problem with the wireless connection i suspect the component has something to do with this, and in addition also because it is placed right next to the Wi-Fi/Bluetooth antenna cable socket. So my questions are: What is the component called?What does is do?How can I re-apply it correctly? Thanks in advance:)
its called utrip_rf its to do with the antennas along the side etc. you wil need a hot air station to put it back on
I know that without this chip, the Wi-Fi will not work. It is called the UTRIP_RF on ZXW, but I am not sure where to find a replacement besides on a Donor Board. You will need a hot air station and you will want to ideally pre-heat the board. Remove all of the underfill from around the chip. Add flux and hit it with hot air. I like to use around 360C. Here are some images of my repair.
Good luck. Hopefully you don’t have to run new traces.
