My mistake - some advice

I just removed a 20x LD from a sony DVD burner. Easy as pie to remove. I installed it in a housing and soldered some wires to the terminals. As was well - it was burning nice. The voltage drop was a little higher than posted here for the 112D LD. I wiggled the LD module and the anode wire twisted slightly, the LD pin spun, and broke the anode bond wire. I've been trying to resolder a wire in its place with no luck. I should have twisted the anode and cathode wires together then soldered them to the LD. The twisted wires would have held rigid and not spun the LD pin and broke the bond wire. Or, I could have soldered the open pin and the anode pin together and this would have prevented the pin from rotating.

I also screwed up by using a solid wire for the anode. I had a stranded wire for the cathode but couldn't find a standed wire for the anode.

You are right, the pins are held rather loosely in these open cans, moreso than other diodes I have used.

In one instance, when I heated the diode to 100C, the pin just fell right out!

hey drlava can you give me an idea how much power output of the bluray laser from the PS3 laser lens, thanks. can i run it using 2 pcs.of RCR123A and a 7805 regulator like rog have? what exactly the power out when using 7805 driver. thanks.

Nice thread hijack. Could PM him or create a thread.
