How to fix earbud board with lost continuity?

crwdns2934249:0crwdne2934249:0:

So I’ve run into a problem. I was dismantling some in-ear headphones for a project and the first one worked out fine but the second has an issue.

There are 4 terminals on the board. All but the bottom right one (in the images) have continuity with each other in the working driver. The driver that is having trouble has lost continuity with the bottom right terminal. I didn’t treat it any differently than the first one but something must have happened. The only thing that makes any sense to me is perhaps I got it too hot when desoldering the terminal.

If this is the case, is there any way to fix it? Any suggestions as to how to troubleshoot any further? If anyone has an idea about how I might salvage this, I would greatly appreciate it.

Please note these aren’t actually Apple headphones but from what I’ve seen of the internals of the Apple ones, these are similar.

Thanks in advance :)
