Harvesting Diode Tutorial *~*~*

[BluRay]

I harvested my first DVD burner diode today. and let me tell you what guys. i was s****ting myself cause i knew how delicate the open can diodes are, and didnt want to touch the little wire you see connected to the pin inside the diode.
Well after getting it all out, (the easy part) it was time to remove it from the heat sink. That took my for ever. I tried the Phr-803t approched and with no success it just remain the same.
But i found out later the easy way. after using a fine tip pliers to remove the little piece of glue from under the diode where the diode is glued onto the heatsink, You can gently fine a fine tip tool and push it out. and it gently comes out. Make sure you dont touch the inside of the diode, and push on the piece behind the 2 pins.

Well thats my way, hope it can help someone

I basically do it BluRay's way. Works like a charm! Remove the glue from the back of the diode, I just scrape it off with pliers like BluRay does. Pinch the heat sink with a table vice (Fairly tight) with the diode facing up. Then take one of those square screwdrivers and touch it to the top of the diode. Tap it lightly and repeatedly with a hammer and it will wedge out. I have only tried this on the open can ones, and wouldn't recommend it for closed can because you might crush the can inwards. Besides that, I really recommend doing it this way, I have ruined diodes trying to snap the heat sink off with wire cutters

nice work bluray and mmykle my first and only open can extraction took at least an hour :-[
to get it from the heatsink. I had to put my wire cutters in my vice with the diode's heatsink in the cutters. I slowly tightened the vice until the heatsink snapped. My diode hit my fridge then fell onto the ground but it was fine.

I guess the moral of the story is be a bit patient but also that people think the open cans are more fragile then they really are ;D

ok soo i watched styropyros youtube video for making a burning blue ray laser, his approach (which i have tried ) is to grap each side of the heat sink with pliers then just bend downwards and *POP* the heat sink breaks and the diode is free, too me like a minute to extract a diode that way, from the PHR-803t sled lol

Guess what?

That diode has a completely different heatsink!

Thanks for the info.  However, this thread is about how to harvest a long open can red diode NOT the PHR-803T sled.

Peace,

So, what's the verdict on removing the long die red?

a. dremel
b. file
c. remove glue and push out
d. visegrips and snap or crush heatsink
e. something else that I missed?

I have two that I still need to extract w/o trashing them. (still in sleds from 1st gb)

I've probably extracted a good 40 or 50 of these in the past few months, and, from my personal experience, I can say that the quickest and most efficient method for extracting open cans from their heatsinks is to use a very sharp pair of wire cutters to snap the heatsink at the point where the side of the open can diode will be facing you. You just need to make sure that you're applying significantly more force to the top of the heatsink, as opposed to the bottom, where much less of it protrudes over the diode. Pics/diagrams and possible a video to follow...

Those are some good tips!

if i find this post a week before i would have 3DVD diode on my hand,

thank you so much that helped a crap load! =)

I use a pair of diagonal cutters as well... i've harvested probably 300 of this things and still mess up sometimes..

I cut off each corner close to the diode, then make 1 more cut on the side nearest the middle pin. Then use your fingers and try and pull the diode out from the heat sink, if it doesn't come out, keep cutting small chunks of metal around the bottom (pin) side freeing up more glorious copper color of the diode, then try pulling it out again.

seems to work pretty well, about 85-95% success rate..

Care to post a video?
I just file each side and then break it in half.

i have ran into a few different heatsinks for the LOC, but usually, 2 of the four side with be thinner than the other two, i simply use a file to file the thinner side down as close to the diode as i can, once the heatsink is cut as far as i'm willing to risk going, i go back to the PHR method with two pairs of pliers.
