Hello,Does anyone have any suggestions on how to replace capacitor on motherboard as the solder does not want to melt when using a conventional solder station or air gun..no matter how long i hold it there it does not want to melt - any ideas?
Not to insult you, but you may simply need a hotter soldering iron. In your situation, it seems that your motherboard vendor used a type of solder that has a higher melting point than your current soldering iron is applying. You really don't have any other feasible options for mounting the replacement capacitor without removing the old/defective one(s). Good luck!
Solder is quickly melted by the iron then the iron is too hot. It should take 2-3 seconds to melt the solder. It's not suggested heating for a longer than 3 seconds. But do not worry too much about this, just focus on making a excellent solder joint & every time you will be quicker to solder the cap on.
