how can i press my diode without any pressing tool or the back part of an aixiz module???

Drill a 5mm hole in a piece of wood and press it in a vice.
Or find something with a ~5mm hole. If you don't have a vice you can still press a diode. However I strongly recommend against most methods without using a way to secure the module from moving since they, obviously, have the risk of the module slipping and that can damage your diode.
 
There's a number of ways to do it if you think on it long enough, but if you want to press it flush & proper where it will point absolutely straight - you're best off with a diode pressing tool like this.

Any other manner, as good as it may seem might work - but the slightest offset that usually cannot be avoided will result in a crooked beam :beer:
 
However you do it you will want to countersink the diode.:beer:

Any 5mm hollow tube like thing will work, and u need a vice to press the diode safely..
it should be able to securely hold the diode without breaking it's pins.. What diode are you using, dont experiment on a working diode you will most likely kill it in the first go.. also read a bit more on laser building you know nothing about it and yet you need answers which you will not understand..
 
i have a lot of weak and broken red and infrared laser diodes can practice with those ones
before press the beautiful :bowdown: 445 m140 laser diode
 
You should have spend a few more bucks to get the one with leads already attached..
They are sold for some reason , that depends on several things, how experienced you
are in pressing a diode, ESD Protection, Soldering Laser diode leads within 1second..
If you are lacking in any of these , you should not try to handle an expensive laser
diode, Thats great you have dead ones lying arround, just have some practice on
them and Remember dont rush anything.. Do one step at a time , it might take a
couple of days to assemble a laser even if it is a JAD kit, and if your not being careful
you will mess it all up every time..

thanks man now iam seriously thinking about buy a diode pressed with the leads atached :beer:
 
If you ready have the diode, just buy a diode press tool. It is waaaaaaaay cheaper than pouring out the cash for a new diode pressed with the leads attached.
 
i dont have the diode :D that means i can buy it with the leads and in the module
 
Even if that is the case, I run my 445nm's in copper modules which means I remove them from the regular module and re-press them in copper. Not the most efficient I know, but at least I don't have to sloder leads to diode pins. I have not practiced enough for that yet, but I will at the end of the summer when I am done with some other commitments which use most of my free time.

The point is, go ahead and get the proper equipment for this hobby as you go along. Just my personal advice, YMMV.
