Doh!

This is why you don't back up the diode with the mount when pressing it out of a heat sink. This is a 4 pin diode from an HP dvd840 drive. It looks like I'll be making an extractor today. Flaminpyro, you may be getting a little competition. :wave:

That's a new one! :crackup:

Well on the second attempt, after some hours of frustration and a broken cutting tool I have a 5.6mm diode extractor. In hindsight, it was probably not such a good idea to try machining a grade 10 bolt without annealing it first, but the results are stupendous. I wanted to use something hard because of the thin walls, but this was probably overkill. Next time I do this I'm just going to use mild steel.

I have included a diagram for any of you budding machinists out there. The more critical sizes are expressed in thousandths of an inch, except for the bore. You might have to sneak up on some of the dimensions to suit your particular AixiZ module. 3/8" bar is a good starting point (12mm is better if you can get it). All the dimensions and everything should really be in metric, but it seems like none of the cheaper machines are set up for it, at least not here in the US. It seems the old curmudgeons are holding us back in the dark ages. (well, not really the dark ages, but bucking the trends in the rest of the world) Feel free to correct me if I'm wrong. I'm still learning the ins and outs of machining.

The diode is now safely out of the module. In the third picture you can now see the 4 pins coming out of this weird diode. Someone posted a pinout for these a while back.

The antenna... Use a disposable antenna!!
IT works for extracting diodes. Refer to my sig Aurora SH-032. There I used an antenna to extract an A140.

I haven't been able to find the pinout for these diodes after several searches. Can anyone shed some light on this for me?

Thanks!

That is too funny. You made my day

Woah. Necropost alert!

We are discussing what is known as the PHR-803T. Here is a link to provide some light shedding. Don't forget to wear your safety glasses!

Thanks for the light! It took a minute of checking links to figure out which was the most useful, apparently my search results come up a little differently than yours.
So what I get is that these diodes are pretty much useless because they are low power - about 90 mW. That isn't a bad thing for me, I plan to use these to build a test bench before committing two 1W IR diodes into a proof of concept model.

Not at all, Jimmy Shawl. They will do at least 250mW. I was easily lighting matches with it before its untimely demise.
