A Perfect Dedome?

Wouldn’t they just cool off once they hit the dedoming solution? Or do you prewarm the solution as well?

I’ve thought of running the emitter while in the solution but then I wised up. I don’t really know if a live emitter could ignite an mek solution but it sure seems like a bad idea…

I think with a new emitter, the phosphorus is wet/mushy “FRESH” if you will and once they are heated up the phosphorus gets hard. Only seen this on the big quad die emitters, normally the single die emitter except for a few XPL’s I never had to remove left over silicone, a blast of canned air takes care of it.

If I’m not going to use any of the emitters I do de-dome immediately I store them in a (plastic) film can, with the fluid I use, till I need them. The phosphorus remains harden, the fluid does nothing to soften it back up. Again just an observation from my personal experience.

Hmmmm, so it anneals somewhat after heating? Interesting…

I was gonna DD an XP-G2 I just got, right out of the tin. Should cook it a while, I guess…

G2’s are simple, 20-30 minutes in Imron Thinner quick blast of air, done!

Sounds easy enough. I’m just cheap enough to not want to ruin any “practicing”. :smiley:

No kidding! You store them in MEK indefinitely? Can I ask why?

Never used MEK, :smiley: Been wanting to try it though? I use three different chemicals, no heat, agitation.I store them Imron Thinner. Just something I pieced together, thru trial and error, most of the clues coming from MEM! (slower process)
The XHP35-50-70’s are quite expensive, slow and steady works best for me!

Ah. Ok… so you have another throw-juice brew as well… but why store them in thinner?

Does gas dedoming work with terpentine or white spirit? Has anybody tried this yet?

Does the whole emitter generally go into the liquid in a solvent de-dome?

Is it done on a mcpcb or? Conceptually it makes sense but I don't understand how the other is presented to the solvent.

I'm new here; never dedomed, reflowed, or even seen a bare emitter.

Thanks!

Yes the whole emitter soldered to the mcpcb is is submersed in the solvent. I fine reflowing undomed emitters a hassle so I make sure it is soldered to the destination mcpcb. Also. The emitters would just bounce around if not attached to anything. Possibly causing bondwire damage. It usually needs to be cleaned up with a tooth pick afterward so that requires the emitter to be attached as well.

Yes, the whole emitter mpcb and all go in the solvent. Generally I use a quarter inch of solvent and gently agitate after 15 minutes to remove the bits left behind that are still touching the emitter.

My latest S4 2B

Perfect clear explanations, thanks!

“NEW” G2 S4 2B :slight_smile: :+1:

Don’t tease us

I don’t tease. Upper de domed emitter is really new xpg2 s4 2b.

I thought new S4 2B's are . I'm confused...

I’ve been using Mek to dedomed xml2 emitters. The results ate not perfect but satisfactory with no silicone left on the done. Is there another solvent or solvents that I can add to the mek to get better results? Ild just try stuff but the idea of randomly mixing chemicals is short lived in my mind :slight_smile:

Yes it is. The funny thing is I can still get 1000+ meters in an L2 host with a single 26650 by choosing emitters with the lowest Vf. In an ass backwards kinda way I measure the current at 4 volts on my power supply and sort them by how much each draws.

Also, with a clear solvent the tint shift is not discernible unless you compare side by side with a rosy xpl hi. In my opinion the S4 2B still makes a great thrower.
