Hi Pi R Squared, Im new so please excuse my noobness. I saw that the Module leads were wrapped together. Did you have to unwrap them with your hands? ( I know weird question) I thought touching the leads would short the module also if I touch the Driver leads. Is this True? im confused.

Nice Build and tutorial It really helps. Thanks
Don't forget your antistatic wrist strap, especially when handling the diode.

I've been using a little 100x pocket microscope for looking at diodes. So far it has been working really
well. More magnification and a wider focal range would be nice though. A jeweler's loupe is better than
nothing, but I've found that it doesn't have quite enough magnification and optical quality. My loupe seems
to have pretty bad chromatic aberration.
Yes I need something like that, I may buy a real microscope one of these days, I would sure like to have one, had a cheap one years ago but not now.

As Tmack said, you have to touch them, but as The Lightning Stalker said, you need to be careful of static electricity.

If you do go that route, also get a pocket one because it's handy for getting into crevices
without having to remove the diode. Each has its uses.

Hw about those head mounted magnifiers? The microscope seem like it could be a bitch.

I've soldered a few diodes and never needed any magnification. Are you guys talking about looking at the pins????

No, this is for checking bond wires, windows, and front facets.
That's it, like the black spots I was referring to above but I don't see anything on the diode window, I bet I could if I had a microscope or if there is nothing on the diode window then its something internal to the diode but you can't tell with the naked eye, so there are times when a microscope can be helpful.

I see why the head magnifier wouldn't be enough now. So you are diagnosing faulty or broken diodes then? So can problems with these components be repaired?

Often no, but in some cases yes, for example the black spots above, if something is burned onto the diode window and can't be cleaned off or if the window itself is defective you could remove the window or decan the diode, some diodes are open can to begin with like some red diodes, now something like a broken bond wire, I read a thread here once where someone claimed to be able to solder things that small but I wouldn't be able to work with something that small even with proper magnification. I imagine a pin broken off a diode may also be repairable in some cases but again too small for me to work with.

It's more along the lines of preventative maintenance. Checking the facets and windows for dirt to clean off before any permanent damage occurs
