Hi,
I have two pcb’s for my old inkjet printer which I am trying unsuccessfully to repair. They have surface mounted parts. I only need one working board.
I am using an Antex 25w soldering iron with a fine needle point, I have tried 0.7mm lead free flux wire and some thinner lead free flux wire.
One board needs a new capacitor but I can not melt the old solder. The soldering iron is making no impression. I was wondering is the iron under powered or is there a special technique for removing solder? Internet searches have suggested everything from a dremel to a torch.
The second board needs a new fuse. When I could not melt the fuse solder I thought I could get away with soldering the new fuse on top of the old one. Again that was a big fail. The solder just kept forming little balls and would not stick to anything or any part of the board. It was as if the board had a Teflon coat. I tried putting solder on the new fuse and then soldering it to the board, but that was just another fail.
I would appreciate any advice to get either board working.
