Hi, I had to check the motherboard of my Iphone 5 after home button problemes The BGA U3 resistor is there but i noticed one resistor close a connector(i don’t know how it called ) is missing. As you can see on the pic , one in the middle of the 3 resistors vanished. Where can i get a free schematics for an iPhone 5, so i can get the correct resistor value ? Which are the other possible ways to get the probleme fixed ? Home button actually works with some pencil’s graphite but Iphone can’t be shaked and has obviously to be steady. Can a soldering dot fix it temporary ? Where to buy this component ? Sorry for my poor english and thanks in advance for help.
The missing component is a ferrite bead (FL5). It’s specs are 120Ohms / 210mA / 01005. You can find them at Digikey.com under the following part number (445-8668-1-ND). It’s the same component as the backlight filter.
yes this is possible to repair, you can either get a resistor from a donor board, and solder it on using a hot air work station or fine soldering tweezers, alternatively as it is a resistor you can just use a small jumper wire method. We repair these all the time, it is easy if you are experienced in micro soldering. Hope this helps.
If a micro jumper is okay , is it possible to solder any resistor since the size is same as the missing one and no matter the value ? ( here a 01005 resistor) Thanks in advance .
