been reading you how to’s and just wanted to get some advice before i dive in…
im soldering a mosfet transistor, but have to remove the old one i have 3 points to desolder and was just going to apply some solder and hope i get it off with tweezers. for something this “basic” would that be easiest for a novice? then clean surface and go through the normal “basic” soldering techniques for surface mount.
I have a 25 watt iron, .015 solder
im trying to attach a pic of my area….am i on the right track thanks…

If you don’t need the old transistor, it’s going to be a lot easier to cut each lead and then remove it individually. Otherwise I’d get a solder sucker or wick/braid to remove the solder. You can probably also get away with trying to heat all the pads at the same time.

I prefer .02 or .031” solder for non-surface mount components, but it’s really not that critical and a lot about personal preference.

I don’t see your picture, did you get an error message when uploading it?

thanks thats funny cause i can see it, im loading it locally duh
sorry
and no i dont need it, its bad

Oh, it’s a surface mount component. The cheapest route is to glop a bunch of solder on the pins and try to keep all of them molten by sequentially touching them with an iron. Then flick it off with tweezers. You can also cut each lead with flush cutters. ChipQuik can be used to keep pins molten for longer periods of time, which is useful if you have lots of pins.

yeah i agree with you on soldering the pins, i guess i was more worried about cutting …..would u think it is also “glued” down from the bottom in addition to the soldering by the manufacturer, if that was the case, soldering would be the best option all the way around. and is the .015 solder ok for this operation?
thanks

with only 3 leads i hope i can just work fast enough to do it, with my lack of experience i will try and avoid cutting even with a magifier it looks a little daunting
since you see it now would the .015 solder work when installing the new one, any any tips for the installation assuming i get if off with relative ease

thanks again for the quick responses

Ideally you’d clean off the pads with wick before putting the new chip on, but you can probably get away without doing that. Have you seen our Surface Mount Soldering 101 video?

Basically you apply a small amount of solder onto the larger pad first, then hold the chip with tweezers and remelt that solder to secure the large pad. Then add small amounts of solder to the other leads. .015 should be perfect for this.
