I have a burned smd capacitor on my gpu, luckily i had found the right capacitor for that burned capacitor on aliexpress. Now to do this i will need to unsolder the old capacitor and solder the new one and i would like to ask you what type of flux should i use for this task? rosin-core flux (RF)? mildly activated rosin (RMA)? or water-soluble flux (WSF)? what type of flux should i use? And btw if i use flux would it damage electronics?
