I use 300degree... how to replace this chip? I've tried 3 times with no luck

300 ?

Try another ic, they may be bad, even if new. some are fake.

mb83 · 01-09-2016, 10:41

Bro 300 is too much??? What temperature should i use? This is ma first time when i change wifi in ip6... Please give me some advice because i do not want to destroy another ic.

Use 220, medium air flow. no board holder.

Use 300 degrees with good flux, but isolate with kapton around.
Make sure IC is perfectly aligned and apply gentle pressure at the end of soldering for good adesion to pcb
Also use good original wifi chips.
Tested every time successfully.

I too have the gray wifi on my iphone 6 any suggestions?

jimchu316 · 02-03-2016, 03:51

check c5202_RF 4.2v, c5204_RF 1.8v,

if Voltage is okay and L5201_RF no 1.35v. replace wifi IC.

thank you so much response, I feel this is the right way!
But if that's not the voltage, I should make a bridge?
Thanks again!

I have the wifi gray, to me the torch works, but does not operate the volume up key and the external microphone (the second), but I wish it were a flat problem ... I have to try
