HDMI port : solder does not melt!
Hello, I specify that I am a beginner in micro-welding.
However, am I the only one with so many problems that prevent me from repairing?
I am currently working on a PS5 motherboard, the problem is that the soldering of the HDMI port is bad (so to redo). I try to desolder the port with a hot air station, but the solder flatly refuses to melt! I tried with several temperatures ranging from 300°C to 450°C, without forgetting to preheat the card. I thought for a long time that the problem was my flux, but... no.
It seems that the alloy that attaches the HDMI port to the motherboard is not tin, otherwise it will melt more easily! In that case, what is it?
I also tested on a PS4 HDMI port: nothing to do, the solder does not melt.
I've tried hot air soldering with a PC motherboard, and everything works fine, which shows that it's not my soldering hardware that's having problems.
Is there something I don't know or am I just being stupid?
Thanks a lot for any help,
