Trouble fitting 803T into AixiZ module

[rog8811]

I just use the back part of the axiz module flipped around

I used to do the same thing but the modules we have been getting lately are a bit tight, I distorted a couple of back ends so went to plan B as above....

Use a SMALL socket - place the socket over the diode - making sure hte pins don't get mutilated - then place the housing, and the socket into a vise = tighten the vise, and viola !  If you do not have a vise - either spend the $8 to buy one, or use a friend's - don't "tap" it into place, you risk knocking things loose.....and that is bad

I totally agree with SenKat - I've "viced" in many-a-diode without a problem. Getting them out is very difficult, though!!

small socket and large channel locks here -ive done 4 1 failed so far :'(

The PHR diodes really don't like going into AixiZ modules sometimes. I must have bent like 5 back parts, when i tightened the vice. It looked as if it is flush, but when i removed it, only the hole on the back part was bent in..

Other times it goes easily. But if you put it in at an angle first, it gets harder. Even hammering doesn't help then...  


Also, the diode should actually be deeper in than just flush, to make 100% sure it is centered perfectly. I never even realized this, untill a few of them went in surprisingly easily.


A "specialised tool" like the one Rog suggested would be ideal for getting them in completelly.

what about some mechanic grease ? never tried ?

IMHO, if you are going to use ANY kind of grease at all, I think it should be a thermal, or conductive grease or paste of some sort. Kind of like killing 2 birds with 1 stone. Please, anybody correct me if I'm wrong about this, OK ? No offense will be taken, in fact, I'd be glad to have that set straight in MY mind also phoenix77/rob

I have on one occassion resorted to a smear of arctic silver to get the 2 birds effect, I wouldn't consider any other lubricant.

Using the back end of the Aixiz module is asking for trouble - they DO bend quite easily, so I now use a small drill bit stop thingie for the job. It is designed to attach to a drill bit, so you cannot drill too deep in whatever you are drilling, and has a small set-screw in it as well. Harbor Freight sells them for $4.00 for an assortment of 10 or something like that. I removed the set-screw, and it works flawlessly. If you are installing ANY diode into an Aixiz module - and it ismply slides all the way into place VERY easily - STOP WHAT YOU ARE DOING ! Either throw that one in the trash, or return it to the spot you purchased it for a refund/replacement, as it was machined incorrectly - and unless you plan on GLUING the diode in place - it will never work properly. I TRY to check all of mine before they go out - on the ones where the diodes are pre-installed, I DEFINITELY check them - and I have no issues with returns or replacements if anyone receives a bunk module. Everyone should ALWAYS save the envelope they receive from me, as you can simply reverse the addresses, and tape it up - and send it back for free - as the post office never cancells the stamps I use !
(SWEET !)
anyways - just either use a drill bit stop thingie, or find a tiny socket that will do the same job - but try to stay away from using the back end of the housing for it - I USED to use that, but have bent too many.

Yeah, some modules actually allow the diode to be loose.. Those are useless..

But i have applied a little solder onto the base of a diode from three sides, removed it with a scalpel, and then pressed it in. The exces solder was stripped away, and i picked it off. The diode was then firmly in place.

But i don't even like soldering to the legs of the diode without putting it into a module at least partially first, for heatsinking, so this might not be a good thing to do. I now only use the loose modules for testing the powers of a batch of diodes at the same current - this way i can put them in, measure and just take them out again.
