What is the reason/how to reapair it this problem:

Under talking the received voice is breaking, make pauses (like poor field power). Some guys say it is a tranceiver problem...

Any advice will be helpfull

Thx,

Do you say if I'm a newbe in hardwer, that this is impossible.

I need hot-air station, and another COBBA.

Questin: If I only have 20W solder station (not air ****er) I could change it? And COBBA: I have to buy another phone with good COBBA or this part purcaseble somewhere? What about COBBA-ID problem? If I chenged COBBA, I have to recalculate FAID, etc.? I dont know this soft modification regretfully <img src="frown.gif" border="0">

Thnx, I wont buy this...

99,99% you don't need to replace COBBA. You need only REHOT it with good flux by hot air station. Non-hot air station can't help this situation...

THX,

I look for a hot-air station at my compony! Maybe i will find one to borrow for a day. Not worth to buy it until I dont run a bigger business <img src="smile.gif" border="0">

You can't replace COBBA IC as you will have to recalibrate it to work. Just reflow COBBA IC and your crackling problems will be solved.

Hi, I just wonder something.

First Flux then Solder (Hot air) or First Hot-Air then Flux ?

Best Regards...

flux then reheat via hot air... just enough to make it "dance" a litte <img src="smile.gif" border="0">

nightxyz · 10-11-2001, 15:55

Hi,

What does it mean "dance a little" ? shake the board after using hot-air ?

While ****ing hot air over (around and sideways) the COBBA IC, the fast moving air creates lift. But the flux acts as a cushion that keeps the BGA down. You will see the COBBA IC move.
