Skyworks SKY77541 module soldering
Recently my iPhone 4 had a bad fall and suddenly after that reception was gone. (it switches from "Searching" to "No Network" on the top left of the screen.) Initially i thought that this has been caused by humidity so i teared down my device to find out whats wrong. (I was using my phone to work out and the volume buttons and silent switch stopped working too. So i was thinking that sweat got into it. But thats not my priority here.) When i reached the logic board using the iFixit tutorial for iPhone 4 page2 step 16, i noticed that the Skyworks SKY77541 (according to tutorial GSM/GRPS Front End Module) wan not mounted to the board anymore. If am not mistaken and getting all these right this should be the reason that reception on my device was gone...(?) So my question is: Is there a way of mounting this chip back on board and what tools or equipment i need to do so? As i mentioned above the side buttons are damaged too and i was thinking to buy new and replace them too. If its impossible to mount the chip back i don't need to purchase any other parts because my phone will be pretty much useless right? Finally I'm attaching a snapshot of the logic board and SKY77541 to get a better view.
Thanks in advance!
Is this a good question?
