Hi all. I need to replace an SMD fuse on my camcorder and this is the first time I have had to do any SMD soldering so your advice would be appreciated. Below is a picture of the board that I am working on and I have highlighted the fuse that needs to be replaced. I managed to zoom in to take this picture but the fuse is really tiny and is sandwiched between other components so this is going to be a new milestone for me. I appreciate that I am going to have to buy a new soldering iron if you could advice on what I need please. I was thinking about putting a big soldering iron across the whole thing so I could heat up both sides in one go but don't know if this is the correct way of going about it? Thank you.

Has anybody tested this product? Posting this question on a Facebook tech group I'm in got a few responses like "that kind of thing corrodes the tips" and "just using normal solder paste is much better" so I'm not looking for generic responses like that, but rather, does anybody know for certain whether this exact product is good or bad for soldering iron tips?

Hi all,
I am testing a USB powered soldering iron. It's made by Kaiweets but I believe it's also sold under other names.
As a standard test, I checked whether there was any voltage leak from the tip - that said the thing runs on USB-C power delivery so am I correct that the whole unit is floating and not grounded? If I check, I measure 90V at the tip but I have a feeling that that is not relevant? Maybe caused by that capacitor between primary and secondary inside the PSU? I do not see current flowing at all.
In other words, do you think it's expected and... -
Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping... -
