do you guys think its OK to recycle capacitors and the like? ive got a bunch of scrap boards with rubycons and etc on them

Re: Recycling parts
If they are a reliable brand, then yes, I sometimes re-use them for older boards. If they are KZG or something, then if they get taken off at all, it's just to put them in a fire.
One thing to bear in mind is that the cap will no longer be able to handle its rated voltage. They become conditioned to whatever voltage they get in the circuit. So, if you pull a 6.3V cap off a 1.5V VRM, it's now only a 1.5V cap.Last edited by c_hegge; 06-28-2013, 08:59 PM.I love putting bad caps and flat batteries in fire and watching them explode!!
No wonder it doesn't work! You installed the jumper wires backwards

Re: Recycling parts
I always recommend against reusing caps from one board to the other, especially motherboards. Even good brands that are years old will have a great degree of degradation, especially those of the ultra-low ESR variety. You're always better off getting new replacements, as the used ones may not be much better off than the ones you're taking out.<--- Badcaps.net Founder

Re: Recycling parts
You can bring an old cap back to like new by a process called reforming. You need a variable power source to do it. Personally, I would buy new as TC said.sigpicThe Sky Is Falling

Re: Recycling parts
Personally, I think it's more than okay as I do it almost all of the time. I haven't had anything I repaired fail again either. Some of my repairs are a few years old now too.Originally posted by luke10050 View Post
Usually, the good capacitor brands like Panasonic, Rubycon, Nichicon, Chemicon, and Sanyo I will reuse with confidence (except for Chemicon KZG/KZJ).
The unreliable brands (pretty much everything else) I may reuse, but only if they aren't bulged, haven't been overheated, and show good ESR on an ESR meter or pass my "spark" test. And of course, I may only use those for a test/temporary repair. Nothing long term unless I really don't care about the hardware I'm repairing and just want to get it going again. One place where I often use the unreliable brands is when I'm building/testing some circuit on my breadboard and need filtering capacitors.
And then there's the "never-use" unreliable brands on my list - Sacon FZ (they like to pop violently for no reason), Rulycon, problematic Nichicon HM/HN with 2001-2004 datecodes, and probably a few others I can't remember right now.
Not if you recondition it like rhomanski mentioned. But even if you don't, most of the good brands will recondition themselves in just a few moments after applying power to the circuit.Originally posted by c_heggeComment

Re: Recycling parts
Let me tell you, I tried recycling some parts to repair one of my monitors but I didn't fully test them.
That monitor is failing once again with symptoms of bad capacitors. It's not too bad yet, but I will have to take it apart again.Comment
