Quartz tubes

Do Quartz tubes in a flash degrade over time?

[3Deep]

Every tube I have replaced the tip's are broken and burn causing it to lose contact nothing wrong with bulb, but I willing to bet they could lose some heat intensity over time.

Do Quartz tubes in a flash degrade over time?

I've always wondered this. I don't know the answer. Same with computers. Aside from software causing issues
do the actual physical components of a motherboard degrade over time? it seems like they do.

If I am not mistaken, capacitors degrade over time, at least the cheaper ones. Inductors should be fine, resistors could if the components re cheap. Integrated circuits degrade with high heat, so it stands to reason that they can develop issues over time. One thing I know for certain is that the RAM can develop "whiskers" that can bridge across gaps and short it out. 'not sure on the time period though.

As far as quartz tubes, i would imagine that everything degrades (even the LEDs contrary to the popular belief), but the question is in what time frame?
If you are talking about MHM bulbs, there are two different kinds out there. The original Calmat are much more expensive and seem to be dimmer than what Hirsch found as a cheaper replacement. Supposedly the originals worked better .  .  .

MSI is what I have

Typically capacitors in a PC environment shouldn't experience excessive heat issue but years ago some capacitors were manufactured with flaws and were prone to swelling and blowing.

There is a lot of myth out there on the internet about soldering cracking from on/off stress and the usual remedy claimed by many is to reflow your soldered chips in toaster ovens. There is videos of people putting GPU's and mother boards in toaster ovens and getting pissed when the end result is worse than what they started with. Thing is manufacturers use lead free solder that has a high flow temp, chances of solder breaking down internally just from normal use is next to zero. The worse things for MB's and circuits is improper cooling for the chips and cigarette smoke. Also installing massive liquid cooled heat sinks and fans onto the MB's can cause cracks in the board which causes shorts.

people putting motherboards in a toaster oven are probably the same ones that tried to drill out the headphone jack on the new iPhones.

Reflowing motherboard/laptops/Xbox is a real thing.

It can be done with ovens... Just need to be careful.

I've fixed a few dv5000 laptops that were notorious for poorly soldered gpu's.  I'd just wrap them in a blanket and let them overheat themselves.

They'd fire up and work like a champ after.  I've never had anyone call me back with a subsequent issue.


Guess it's a good think I'm an android guy.

It was done with an oven the first time, now you tell me I can use my oven to fix the crappy job they did originally?   

BTW, if you decide to invest serious time into reflowing, you can get a hot air rework station for like fifty bucks...
I don't know how long the caps will last though.

My girl friend is a component level repair person. She works under high powered microscopes and uses rework stations. Not saying  reflowing in an oven is not possible but more often than not you couldnt get the board hot enough to flow leaded solder and not also damage other components.

For fifty bucks and a hot air rework station you could fix just about anything if you have board schematics and access to needed parts. Plus they sell special heat tape to protect certain components from excess heat while working on them.

Or you can buy one of these, they only cost a few bucks

LOL what does any of this have to do with quartz tubes

We can thank eb for starting the tangent of other electrical components wearing out in time, and then their ensuing myths and fixes.
I've always marveled at how dynamic threads can be even without intentional hijacks.
