I have some mosfets that I would like to replace with new ones. (They are N310AS) I bought a few new ones from Mouser. (The part number on them are NF30AB made by Fairchild)
I would like to replace 4 of them. Not sure if they are going bad or not. One of them gets pretty hot.(at least I know it did before I recapped it, you can see some of the green coating missing from the board around it) The board still works after I recapped it.
I had to recap it, as it was dead.
My questions are, What is the best way to unsolder and remove the old ones? And the correct way to solder in the new ones? What end gets soldered first, the heat sink side or the side with the 2 legs? And what type of iron would be the best to use with what type of solder?
