solderless ld connection

explsvcookie257 · Feb 3, 2008

Hi all im currently working on my burning laser and since my soldering skills are not great I was wondering if you could take the the thing in a maglite that holds the led bulb and solder wires to the metal tab and the positive connection and then just stick the ld in the aixis housing i the holes where the light would go and then put that in the dorcy. Im pretty sure this would work and when i get my dorcy metal gear or junior i will solder 2 10 ohm resitors(thats what i decided from reading all the posts about kenoms how to for the dorcy mod). on monday i will post a drawing of what im taking about.

thanks

ok i read that

well what if i hot glued it in and when the diode eventualy died eve though i hope it to last a awhile i could just cut off the glue?

It's not worth the risk to use a connector no matter what you do.

ok well im not going to do that now but i will have to try and find someone who can solder the ld for me cuz i personly dont think i can do it without messing it up even with heatsinking butt i guese i wil have to practice but thansk for the input. this forum has helped me allot cuz ive read so much stuff on it. once i make my laser i will post pics and what not

All right man, I'll be waiting for all those pics and videos ;D
I too need some help with soldering the cap and wires to the diode, I too have done a lot of research and know how to make everything and the only thing I'm missing is how to solder to the LD, is there a special way to do it so you don't kill it so easily. :-?

well what ive read is you need to heatsink the diode pins with something lie pliers or alligator clips or radio shack heatsink clip Catalog #: 276-1567

I know you have to heatsink it, in fact mine is already in an aixiz housing, I'll also be puting aligator clips on the pins of the diode too, but I don't think I can solder fast enough.

EDIT: Gazoo, how do you solder your diodes, do you use some kind of top secret method only known to advanced laserers? ;D

explsvcookie257 · Feb 3, 2008

yeah same and by heeatsinking i meant keeping heat on the pins and off the diode and i too got my aixis housing yesterday only took about a week but im still trying to find either a dorcy metal gear or a dorcy jr flashlight host and then i have to go buy 2 10 ohm resitors to get the curent to like 230 or so.

There easy to solder too, what i recomend is you dont solder a cap straight to the diode, solder 2 small wires around 1/2inch or so to it by first putting a blob of solder on the wire then a blob of solder on the ld (make sure its in a aixis module while you do this) then you simply touch the two blobs of solder quickly apply heat and they will melt together, has worked every time for me.. then once you get those wires on it solder a capacitor to those wires so you dont put any more heat on the ld.

...lazer... ;D ;D ;D

All right, thanks for the help woo.

I solder the capacitor directly to the diode. One leg at a time, once the first leg is soldered the second one is easy. Then I solder the wires to the capacitor. However you could solder the wires to the capacitor first. Whatever is easiest for you. The laser diodes are pretty heat resistant. As long as you have it heatsinked, you should not need to use alligator clips or anything else. I never do and never have and I have only killed one diode due to excessive heat. The reason was I got solder on the positive pin of the diode between the pin and the back of the case. I tried to get it off to no avail. :'(

Using a tiny bit of flux would help too, but I never do.

Ok thanks for the help you guys ill cut off some l.e.d. leads and solder them to the pins on the diode and i have one more question is it safe to bend the diode pins just so u dnt get any solder on the other pins accidently?

Where did you get the diode from? If you got it from stonetek, you don't need to solder led leads to the leads of the diode.

You can bend the pins of the diode to spread them out some. Just don't bend them back and forth too many times...they do easily break off.

ok thanks for the input gazoo and yes i did get it from senkat at stonetek.org i thinks thats the corect name. i will try my luck at soldering tomorow

You can always practice soldering to the leads of led's before you attempt to solder to your laser diode..

Good luck..
