Anyone know how remove the internal components from this type of host safely

https://www.google.com/search?q=sdl...Ud27DIKEygH0voDgDg#biv=i|25;d|fjuRYs1H6gXJGM:

I bought a 50mw 532nm from ledshoppe and it worked the first day but now it's not doing anything and wanted to check and see if the wiring need to be re-soldering but it seems to be imbedded in a type of "washer" approximately 3mm thick, I can't figure a single way to get it out without destroying the host

This was in the search you provided. Every part laid out. Pretty straight forward.
To what "washer" are you referring? :thinking:

Yes exactly, but i can't seem to unscrew the top part of the laser closest to the diode it's self it just won't budge, doesn't even look like it should unscrew

What top part? There is the focusing part and below that the threaded part that unscrews. It may be on tight and or manufactured with some sort of glue. It may require a heat gun and some strap wrenches to loosen.

heat it up, wear gloves, and twist hard. Like I said, you may need a heat gun. Maybe a hair dryer will work. Don't grip it with pliers. That will for sure scratch it or damage it.

Okay so I go that down now how do I extract the internal components? I'm thinking the solder is melted where the circuit board it soldered to the diode I want to get to that part

That aluminum part is your heatsink and is wrapped around the green module. It should pull out once the front is removed. As you can see from the picture the driver is soldered directly to the pump diode. There will be two of the pins soldered to the same pad on one side and the third pin soldered to the opposite side of the driver by itself.

Use a macro setting if your on your phone and adequate lighting. Make sure its in focus.

This is the best I could take without it being super blurry bad ipad 2 camera lol but yeah I don't really know much about soldering, I'm only 17 I would gladly send it to some one on here to fix it for me I'll pay shipping both ways plus the cost of supplies to fix it if its even worth fixing it was only 34$ the circuit board broke off bout 5 mins ago so yeah

Its a little blurry. I see one collapsed pin and the others appear to be missing?

both the pins that have the little black circles around them are your negative. (well one is the other is just hanging out for fun) These are the ones that are soldered together on one side of the driver.

The pin that doesnt have the black circle and looks like its touching the case of the diode is your positive and soldered to the opposite side of the driver.

Sadly if your pins are bent, straightening them will most likely result in them snapping off. If they are missing then there really isn't anything you can do.

Maybe contact the person you purchased it from. There is also a possibility you can find a green module the same or similar to the one in there and just replay it. I cant say I have seen any around that short but you may get lucky.

Thanks for all your help man, I was a lost cause before you came to the rescue.

I can now say I'm officially addicted to lasers.
