How to extract A-140 diodes from projector ?

[Tabish]

Like the title says. How do I extract diodes from the laser array ?

This video shows it's easy to take out the array itself :

YouTube - XJ-A140 445nm Laser Array

Is it difficult to get the diodes out from the heatsink ?

Are they glued in ? They must surely be soldered in.

They are not glued in or soldered in
The only thing holding them in place is a bit of non hardening thermal compound and there ribbon cable.
Once you detach the cable a slight push will drop them out of the heatsink.
i extracted 48 lasers in under 30min not counting all the playing around i did with all the parts.
And so far there has not been one dead laser all perfectly working .

^ thats good news, i haven't taken the projector any further apart than what you see in
the vid. Its good to know it will be easy to harvest when the time comes.

oh yeah i harvested every part from mine and have had so much fun. it has a nice copper tec in it.
But if your thinking of extracting everything you will want a ton of anti static safety measures.
A esd mat, esd wristband, esd containers, and esd protected iron.
If you are missing even one of those you are risking killing the lasers.

Yup, not a problem, i the mat and plenty of baggies

Yup they are always good to have.
I am more curios as to what the point of the thread is he going to be buying a projector to extract or is it just curiosity of how we do it?
