How to replace SMD-microphone. SE Mobile

silversweden · 14th November 2008, 10:42 AM

Hello!
I have a Sony Ericsson w880i with a bad microphone.
No guarranty left!

A new Mic arrived in my mailbox this week but i dont
know how to replace it!

What tools do i need? Maybe i could use some type of hand
held heat-iron?

Any advice are welcome!

I assume its a back electret mic of cylindrical construction?

Be careful not to overheat it! Anything smaller than a 6mm diameter really needs a heatsink when soldering or else the diaphragm will just vaporize.

Of course, opening up the cellphone in the first place is pretty tricky.

good luck!
