I've looked through numerous threads and can't find a proven method of removing diodes from the Nichia 8 diode bank. I have a Nichia NUBM06 32 watt 445nm 8x diode bank. I am reaching out to anyone who can help me extract these diodes safely. I believe they are soldered in. But what is a safe temperature to melt the solder and not kill the diodes. They have designed it to be tough to remove, but I'm sure it's being done by quite a few people out there. I know I could cut them out but that will be time consuming and might cause damage.

I haven't torn one down yet, but I expect you are going to need to do some cutting and pealing....carefully, just heating it sounds like a very bad idea.
Yeah I agree. Heating it without knowing the specific temp is probably not advisable. I'm sure high power diodes reach a pretty high temp rite at the chip when running. I don't know how hot they get but I'm sure it's up there. They were soldered in but in a very controlled way.

I wish it wasn't a secret. I don't see why it has to be kept from the public. It would greatly help the hobby if people shared this info.
Yeah I understand some people make a profit from extracting diodes from these banks. I can't ever be mad at someone for for making a buck. But it would be be good to know. If someone knows and doesn't want the world to know feel free to private message me there's a free diode in it for you and your secret will be safe.

I think its similar to why you wont really find any information on what projectors give what diodes. Its probably to avoid copyright/legal issues to the forum.

Copyrights for removal though?

That is correct, that's why we can't use the word Ca$10 in the forum, they don't want their products torn apart to extract laser diodes, they know about us and that's why these diode banks have been developed to be extraction resistant.

I didn't know that. That's messed up :O
It's understandable companies don't want us extracting diodes, waving them around in handheld form. It's a huge liability for a company. As diodes get more powerful people need to do more to protect our hobbie from bad publicity. That's for sure.

I'm not planning on using any heat, maybe a heated xacto knife blade in vice grips after the cracking to loose the edge but likely no heat, if I can I am going to repurpose the entire block employing some of the factory optics. It all passes through the phosphor wheel in a cluster, some telescope optics and ......well who knows, I must see what's in there, the moment the parent unit hits my price I will find out, at worst I wreck the whole thing, no guts no glory.
