Anyone here every repair a broken USB stick?

I thought the USB male connection was loose from the board so I stripped down the cover and it turns out that's not the issue. So I'm assuming re-soldering the 4 connectors (pictured) is what is required?

I only have a flux pen and heat gun on me, would that do any justice?

I don't want to send it to a hardware recovery shop until I have tried to fix it myself.
