Well.... I killed it.

Yes… I killed a cheap zoomie with an XML-T6 today. I thought I’d take a shot at dedoming it.
I should have soaked it, or cut it off I suppose, but I thought I’d try just pulling it off if it didn’t seem too stuck.

It actually popped off fairly easily, but, it’s completely dead. Not even a flicker.

Words of wisdom…. Don’t yank your dome!

Dome Yanking? That’s a paddlin’.

:stuck_out_tongue:

Just soak it in gas till the dome falls off, easy peasy.

You probably broke/pulled off the tiny leads (very hard to see). They are (or were) kind of embedded in the dome. You can probably easily replace the emitter+star.

Doh!

Soak it in gas as in car fuel? Does that have any ill effect on the phosphor? How do you clean off the toxic residue afterward?

I have this charger that has a rejuvenation setting which I use occasionally. I don't know if it would work in your case though.

Duh? :~ :stuck_out_tongue:

Was that supposed to be here ?

Indeed! Our other-side-of-the-world friend has a lot of tabs open, I guess. But we must forgive him, it has to be difficult to live all your life upside down

About the dedome, yes, leaving it in gasoline for a few hours do the job. Many clean it afterwards with isopropyl Alcohol (I did it too) and it seems to leave the phosphor alone in its place

yup…ripped off the tiny gold traces from the die to the top of the emitter stratta….bummer, fixable with a reflow

Car fuel is very clean stuff by itself.
It’s proven to be the best way to dedome.
The dome falls apart and detaches from the chip.
Leave it in a tiny glass, submerged in the fuell for 24 hours, shake it around a bit, and there will only be some remains under the bond wires, if at all.
I use some IPA (alcohol) to rinse it afterwards, but maybe it’s not even necessary.
The phosphor layer is not affected.
I was surprised too, as car fuell is also a powerful solvent.

There are many topics about ‘dedoming’ why and how to be found here.

You don't really need to rinse it afterwards as gasoline is fugitive (evaporates completely), and alcohol almost always has water in it.

Sometimes it floats off on it's own, sometimes it needs a nudge from a toothpick or tweezers. I've also had luck putting a thumbnail on each side and squeezing it like a pimple. The dome pops straight off. :Sp

I have IPA in a spray can, so it stays pure.
Come to think of it, it’s running low, should order new…

I hope you’re not talking about India Pale Ale :stuck_out_tongue:

Isopropyl……Alcohol :smiley:

Isopropyl Alcohol = Propanol, so you could say just “P” for short :slight_smile:
