My diode is loose in the aixiz housing?

[explsvcookie257]

Well tonight I am going to solder my diode to the circuit i got from rckstr. So I was putting them in roach clips and realized before I did that that the diode is loose in the housing. :-? I can twist the whole thing around the diode with ease but if i pull the diode out a bit it gets tight. Is this normal or is it just me and also note I did take it apart but it was loose before that.

Thanks for all the help so far

It's not normal, but it does happen.

Most of my diodes would stick in there really hard, but i did come across one, that was loose, almost like you describe.

I simply used a soldering iron and soldered it in at the sides (edges of the base of the diode to the AixiZ module). If you can take it out, you could just add some solder to the sides of the diode, and then push it in using the vice method. The force will push the solder away and the diode will be stuck firmly in place.

Whatever you do, just be carefull, that you don't solder the positive pin to the leg of the diode. It can even happen, when you have the diode upside down and the molten solder flows down, while soldering a wire to it.

Ok thanks I will try that tonight

That sounds really bad, if its not contacting the metal good enough the diode will not conduct the heat away and it would kill itself, try to find some heatsinking compound and put a small amount of that around the diode, that should help it out alot.

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

Arctic 5 epoxy ??

well i put of soldering it for tonight im going to try and maybe find that arctic 5 epoxy. If I pull on the diode i can make it come out like less then half a mm. But i think arctic silver 5 thermal compound for cpu's will work just as well maybe. I also have a question should i solder wires to the diode then the driver so i have a less likely chance of messing up the diode trying to to solder it to the board and so it cant break away. If i did just solder it to the board could i use hot glue or sum thing to keep the connection from breaking because you cant use hardly any solder with out accidentally making a bridge between the contacts. Any ideas on how to keep solder from flowing onto the other contacts?

sorry If i ask to many questions. :-[

Most of us here solder the wires directly on the diode's legs. I suggest you solder the capacitor to the diode's legs too. Some people solder it onto the board, but if you disconnect the diode from the capacitor while the power is on the capacitor will charge up with all the voltage and current from the batteries and when you reconnect it to the diode it will dump all of that into it and thus kill it. But if you solder the capacitor to the diode's legs you won't have to worry about that happening.

What I did with a blue ray with all the pins broken off was to scratch off the plating in the area where there is a notch in the LD housing, push the negative leg of the capacitor into the notch and solder it in place.

This will make sure the capacitor is in the best place in the circuit, as chido says above, plus the capacitor leg will tighten the LD in the housing and the solder will fill around it to give a better heat sinking path.

The only down side is that you will be puting quite a bit of heat into the diode to get the solder to flow, all I can say is mine survived with no problems.
