Extracting Diodes From Nichia diode bank






It's good to get our hands in there and play the game, nice haul of diodes Ricker, I know you are having fun, you got those cuts dialed in good.

I'm going to test some methods and see how it goes. I wonder how many people would like a fresh nubm06, mine is a powerhouse.
I'm going to have to get a LPM so I can post real numbers, but that NUBM06 is strong.
I still love the NUBM44 too, they are my best corrected blue burners right now.

I have it nailed down now, after I get my deep well circle cutters and attach a stop ring for the depth I think a can use a brass punch and hand fit it, even use my large vise to push them through.

Heck for 20 dollars on flebay I can skin this cat. I can use a good quality deep well 7mm socket for a press, I have lots of tools, old snap on and craftsman from my auto days, I have multiples of everything.

This is all I need to buy:

This

This
THIS

THIS will do just fine. I can use a longer bolt, but I will add a stationary plate with a cutouts so it the socket presses without turning, or my large vise and a small socket. The big vise would be better, no need to build something for the sake of doing it.

THIS would be total overkill.

It's a simple concept, the right diameter hole saw to fit the round pocket on the back and cut within a fraction of the diode back, then use a deep wall socket to push it through in a large vise.

Hell forget the socket I will push it through with the hole cutter. ;)

START OVER, RIGHT SIZE HOLE CUTTER and a large VISE, Cut just short of hitting diode back, I will make a guide plate, press through with hole cutter in place, simple.

A little fine tuning and I could do it production line style, I could with an assortment of those diamond cutters start with what fits and work up to widen the sides until it falls out, just a matter of sitting and playing with it, with the windows/Gball well protected of course.

I like it!!! I would love to see this in action!!
Another picture for you! This is my handheld 60-120X pocket microscope being used, which works perfect for seeing a diode window, check out this dirty girl. This is one of the first diodes I did when I only covered it over with tape like half the time, But I got my First Contact solution so this will be solved sometime this week!!

Like that you guys keep at it. There's always a way.

Thanks Pman! If someone else can learn from my mistakes, it's all worth it, plus I want to keep this thread alive so someone else that may have some information can chime in as well! :)
 
You did a pretty good job getting those out. I just finished getting all of the diodes out of the block on mine. It will be nice if we can make a tool for this. I'm sure there's one out there in the world. I only used a drill press and cutters this time. I used a really small drill bit and made perforated lInes where I wanted to make a break. This way was a lot easier and didn't even cause the block to get warm or subject it to a lot of vibrations.
I'm glad people are getting in on this thread. When I first started there was very little to go on. Now we have some legit knowledge to reference. I hope we can keep refining out methods. I just hope none of the company's like Nichia see it and find other ways of making it more difficult to remove the diodes. But I think the way they configure the diodes now won't change at least for a little while.

Hi Alex,
Maybe Nichia should make it easier to get them out this way we would purchase more of their block arrays, they make money and we get diodes.

Rich:)
 
I'm not going to talk about what they did that made it harder or easier, and what I see that they could do to make it harder or easier, that would not be a good idea.

There are some politics at work and we do ourselves a favor not to say those things.

I do think they build great light sources with fantastic tolerances, I am impressed with their product, they build quality, just on tolerances alone they can put any 8 diodes out of a bin into a block and they run parallel, that's some excellent manufacturing quality.
 
Hi Red,
Wow well put there quality control is impeccable in most cases . yes we must leave well enough alone for now, It isn't that bad as of yet . And yes i am very impressed with their quality also many times over..

Rich:)
 
Yes definitely. You have to appreciate those Japanese scientists working hard to make science fiction a reality. Big thanks to Nichia.
 
Yes they do a great job, I feel bad that so many scammers and con-artists in Japan and mostly China make crap and sell crap which gives those countries a bad name, when there's great products being produced as well.

Wednesday and Thursday I'm going to start checking lenses, cleaning lenses, and testing diodes! I'll keep you all informed, I also have another block to disect, not sure which route to go with but I might start that this weekend (my weekend is Wednesday and Thursday) as well. And when I get them all tested I'll send you out your gift RC, do you want some metal from the block to do some tests with too?
 
Sure, I can always compare if I get another block just to see that they are the same.

I know the 08e is going to be in one of these new boxes soon, but they are all expensive, but I'm keeping a lookout, just like the V is an economy unit there will be others and they will run the latest as they are not expensive for the box makers.
 
I am confused on that pic. Are you saying that whole black area is the dirty part of the lens? If so, how did it get so bad? Sorry if I missed what happened but it sounds like you covered it with tape and that's residue and you are going to use contact solution to clean it. Does that sound right or am I way off? I'm not questioning what works, I'm questioning my own understanding of what you are saying.
 
The pic looks upside down and out of focus a little, that top is the wave guide and on the bottom you see the bond wires and the emitter and AS device in the middle, those tiny specs are on the window.

Hey Ricker you said you were going to use contact solution to clean them? I'm just speaking from my experience and people my have other preferences but so for for me the only thing that has worked and not made things worse is the LENSPEN I think they are under $10 bucks and you can find them in the camera section at Wal-Mart. Just go very lightly with it and used canned air also. But don't blast it with air just lightly hit it at an angle. Not strait at it. Also make sure you have the can level so squirt frozen liquid at it.
