Re: New Members - please post your introductions here
Hello
I signed up quite some time ago but on a hunt for things I came across this site yet again, logged in and now, I suspect that I might have already entered a note here but as I am unsure I thought I better follow the rule again.
A lot of what I do relates to archival and some of what I do relates to small simple repairs such as recapping old boards. I am by no means trained in electronics but I wish I was because it is such a fascinating field. Nonetheless, I have all the necessary tools for soldering...

Re: Tantalum Capacitor desoldering- safety concerns
Just a quick follow-up on my process.
1) add a liberal amount of isopropyl alcohol around the cap
2) add flux to both the + and - side of the cap
3) With the iron already hot, contact the terminal and add a good amount of solder to both sides
4) Alternate back and forth between each side while gently rocking or lifting the cap. This relies on my sense of feel but I maintain a gentle tug while alternating.
This has proved the quickest method for me. I have pulled 20+ caps since my last...Leave a comment:

Re: Tantalum Capacitor desoldering- safety concerns
Guys, I figure out a method.
I put an ample amount of flux and then soak fresh solder onto the pads. Then I heat up with 400°C which is what I found works. I alternate between sides with the iron while gripping the cap with small players. As I draw heat to each side I gently wiggle the cap until it begins to lift on one side. If needed I add more solder as this creates a nice heat reservoir.
After two minutes the cap is off, I clean up the excess solder with a copper braid and then clean with isopropyl...Leave a comment:

Re: Tantalum Capacitor desoldering- safety concerns
Some folks really are against this as pads might come off as a result.
Maybe I just have to purchase desoldering iron tweezers, they can come handy in these cases, at least for me.

Re: Tantalum Capacitor desoldering- safety concerns
Thanks stj and R_J. I desolder my first tantalum. What appears to be 10x harder are the small electrolytic caps, man are they ever tough to remove. I avoid bending or rocking the cap, maybe that's why but I can't risk damaging the pads.
Thanks again!Leave a comment:

Tantalum Capacitor desoldering- safety concerns
Dear members
I have the TS100 soldering iron, not a tweezer type and some tantalum capacitors that I need to remove.
Considering the tools I have, desoldering braid, flux and the iron but are there safety concerns to account for? Namely the tantalums blowing up? I will use glasses but I wanted to know if this is legitimate concern or an event that happens with very little frequency.
Kind regards

Hello, thank you for visiting my 'visitor page'. As an FYI, I joined this forum to learn more. My knowledge is still very brief. I have some basic soldering skills but still need to learn a lot. All the best to you. -
Re: How to Recondition (Reform) Electrolytic Capacitors and Why
Interesting stuff but it made me wonder. If I have devices stirring around unplugged for months on end, well how would this evaluation or consideration play out on some old device that only gets plugged in once a year. It would appear that the running logic you outlined would suggest that we power stuff up regularly to avoid degradation.
What are your thoughts?Leave a comment:

Hello everyone
I'll keep it short.
First of all, I found this awesome forum because I started doing research on ESR meters and then found myself reading this sweetest of sites, [url]http://www.capacitorlab.com/failed-recapping/index.htm[/url]. An amazing document.
So other than that, I baby-sit a bunch of old Macs and started knowing zilch, still know zilch. I have only done some very minor soldering, desoldering, got myself a cheap multimeter and it looks like the next thing on my...Leave a comment:
