Re: Component fallen off a scope board

Hi, thanks for all the useful advice. Sorry it took me so long to reply. I tried to solder the broken legs with a standard soldering iron (thanks rebornonline for the suggestion). In particular, I followed the tips given in this video that details soldering of SMD components:

Re: Component fallen off a scope board

Hi. Thanks for all the support.

I didn't even try to solder the DSP legs. I don't think I have the right tools. The tip of my soldering iron is too big and have no experience in doing this kind of job. If you could point me to any web page which explains how this can be done with a soldering iron ...

Re: Component fallen off a scope board

Unfortunately the story has a sad end.

Re: Component fallen off a scope board

Hi,

the broken cap prevented me from installing me the board at all. I guess the suggestion coming from all these comments is to first try it anyway. I will do it tomorrow, hoping I find the time.

Re: Component fallen off a scope board

Thanks for the advice. Knowing that the board might work even without that cap is an enormous relief.

I have some soldering experience, so I would like to solder the capacitor back on. Since the capacitor appears to me as polarized, my next problem is: which way should I solder it? I think the ...

Component fallen off a scope board

Hello, this is my first post and I am rather sad. I just bought a used scope card, but the card turns out to be damaged: in the box that contained the board there was an electronic component floating around. See here the component near the spot where it belongs:
