before you reheat the mic module you need to resolder under mic module put led then after that mildly reheat mic

NOTE: don't put a flux dont forget the mic module of 53410express is very sensitive.

post the result...

here is the tip that might help you

before you reheat the digital mic module

put some cover on it,you can use keypad mat as a cover

but before that, you may put a bit of double sided tape between keypad mat & mic

module, so that it would be stable

like this

forget about all the tips before

it works very easy with just a cheap hotair...

1.) desolder old mic
2.) clean contact pads and resloder cleaned pads (not to mutch, not to less)
3.) see on back side of the mainboard, if there is something like connectors (you have clean backside with no connectors on 5310 board), then use some tape to save it from heat.
4.) now use some flux or soldering paste and fix the new mic on right place.
5.) begin now ON BACK SIDE of mainboard to heat the position where the mic is on other side...
5.) now you will see, the mic will fix it self on right place and you have won!

its realy the eaysest way... try this way and you will no more demage any mic...

but be cearfull when there are some components on backside...
its no problem when there are some capacitors or resistors, ic´s ... thats all no problem... you even dont need to save it from head...

but be cearfull on plastic parts... this parts need to be removed first if you work with hotair in with my technic by heating from backside of pcb.

good luck!

ps: @ralel
i need to test your tip on boards where many components on backside... looks also good working..

i teached my methode many technicans and they have 100% success with my methode, because its very easy when no components on backside of pcb.

more info

instead of heating the PCB at the backside

im using this method for almost 5years and all is working

by this method there no other components would be damage

like 2 keypad/UI ic & keypad connector which is placed on the pcb back side

For me to not have a long problem

Why not be able to do this option

Try jumper from the mic than go to board

100% tested no problems with new mic

The better you than to reheat
