FP2 Bottom Module needed in Hamburg/Germany

[thomiel]

Sadly, I missed the deadling of @Leo_TheCrafter to order a Bottom Module replacement, so I’m looking for the original part again.

It’s the usual microphone issue. I already tried to fix it but had no luck.

Welcome to the forum, it’s good to know you tried to fix it. Did you read the posts from people here?

Of course have you considered getting a electronics shop to do the work given how long it may take to acquire one

Hi,
I also missed leo_thecrafter’s offer for a bottom module. Is there any chance to get a replacement?

[thomiel]

@anon9989719 I tried here and elsewhere, yes. And no, I have not considered to let an electronics shop do the work because what’s the point in having a DIY-phone (unless very special treatments are necessary like SMD soldering).

I tried disassembling the module and putting a piece of plastic below the contacts as one user suggested who had similar symptoms.

I think there is no option to repair the mic other than soldering. FP intention is not that users can repair the modules the intention is to replace easy if broken. Unfortunately there was a higher need of bottom modules as expected so its sold out and one must hope for second hand.

@yvmuell What would be a good starting point to search for soldering instructions to repair the mic? Maybe I can find some help in a maker space or repair café.

Howto repair the microphone inside the bottom module

As fairphone angel (in Berlin) I have a lot of support cases with nonfunctional microphones in the bottom modul. A lot of users have minimum the 2nd, often the 3rd bottom module. Mostly easily changed by Fairphone support in warranty. But there is a lot of waste (I collect old faulty modules and send them back for recycling). So my questions: Did anyone successfully repaired the microphone inside the bottom module by soldering a new smd microphone? What’s the reason for the highly rate of f…

FP2 Bottom Module: Repair broken µUSB port and or mic

Hey, just desoldered my microphone from the bottom module. the (very thin) pcb is glued into the plastic case of the module. But with a heatgun the glue softened and you can pull it out. After that I put my heatgun on 380°C and desoldered the mic. I coverd the surrounding parts with kapton tape. But I ripped one half of one solderpad off the pcd(see picture, top right pad). The trace from that pad seemed to be connected to a via next to it. [image] That was written on my mic: S1263 277…

FP2 Bottom Module: Repair broken µUSB port and or mic

Hi, I also want to share my experience with repairing the microphone. From one day to the next my microphone didn’t want to work anymore. This was not the first time but now, I can’t buy a new bottom module… I read a few times that the pcb tracks are maybe cracked. So I opend my bottom module, heated it up to soften the glue and the solder and removed the microphone from the pcb. And the result was: All three tracks are broken (now) (see picture below)… The solderpads of the pcb were …
