Hi all,

a question to the tech-wizards here.

Do Phoenixboards require re-capping?

As mine is one of the original ones and it seems that I need to do some serious re-work on my "Paladin"-system I thought this could be an opportunity to do whatever is required on the actual board as well. The battery is already replaced with a coin cell.

What do you think?

One feedback I got was "no, doesn't need recapping as the Phoenix has Tantals".

Thanks,
McT

This is a great (and scary) question!

I've only seen people recommend replacement of electrolytic capacitors, due to leakage potential.
Tantalums...well, those fail in a different, more "magnificent" fashion. Damage ranges from a badly burned board to a total hole blown right through it, from what I have seen. Is it wise to replace them? What about ceramic caps, which can short disastrously and kill stuff on aboard? That's a question I'd like to see answered as well, so, I am tagging along. Personally, I can't see a reason to do anything other than electrolytic, unless they are testing out of spec, or you're noticing any kind of weird behavior from the Phoenix.

In plain English... I'd just leave them alone. Electrolytics are known to leak and fail, but, the others (tantalum and ceramic) don't -- instead they just explode or short out. Will it happen? Maybe, maybe not. I suppose you could remove them from circuit and test their values to make sure they are within spec, but, is it worth doing so? Probably not.
