Furry IT I need your help/advice
2 years ago
So Furry IT ( I know there is a LOT of you out there ;P ) I am in need of your assistance. First let me say I am pretty good with watching vids, and doing things to fix my computer and other issues. So when I'm asking for help I REALLLY need it. So here is the issue. My wife's MSI Ms-16r4 laptop stopped charging. So after watching a few vids we determined it was either the charger or the charging port. I borrowed a multimeter and found out the charger was working, but the charging port was not. So I went watch a video on how to change out the port. I found the part on Amazon, ordered it, it came in; now it's time to work. SO in order to replace this part you must desolder 5 pins on the mother board, then once removed, you clean and then put the new part in and add solder to the 5 pins. I saw this done on youtube to the same model....So I get a desoldering kit since I have the iron already. I can't get the solder to come off or even melt. I'm using flux and one of those ribbons to catch solder... I thought maybe its my solder iron and or I'm not that experienced with doing this. So I got a friend who repairs game systems. He is pretty decent at soldering. He starts to work on it with his tools....nothing. It's not melting or coming off...He even turns up the temp on this iron and nothing. So we are stumped....I know its do able. I've seen vids but I dont know where we are going wrong. So if there is anyone out there that could give some advice or help I would be really appreciative.
In short: I don't know, what makes that substance melt, but it's a bother indeed. I will try to look after it, but hopefully some IT furry will post the answer way before that, so you can fix that minor part-exchange and have your laptop running again!

Adding fresh solder will make it easier to melt the rest. The flux in kester 44 is fantastic and doesn't need cleanup technically.
A solder sucker is also helpful. They're manual spring loaded pumps. 10 bucks again.
The best thing to have is a temperature controlled soldering station with power behind it. I like my FX 888d but that is about $120. There are cheaper clones. Check reddit for model advice.
Good luck!
What iron do you have? The pencils without temp control aren't great. If the tip is pitted or oxidized it also will have issues. Solder globs and slides right off that.
63/37 solidifies instantly instead of going through a plastic phase (called eutectic solder). 60/40 is decent though. Avoid 40/60. And make sure whatever you get has nice rosin or rosin mildly activated flux.
Also, as Sentharn points out, adding a bit of solder to the iron and using the blob of liquid solder to transfer heat to the pins will help. Be VERY careful if you try to use a heat gun. A hair dryer won't be too much, but a heat gun will do the job too well if you aren't careful. You'll desolder far more than you intended.
Also, make sure you choose the right solder. Here's some help in that department.
