I just got my new 12x blu-ray burner today, opened it up, and extracted the diode from it. Following a video by Rkcstr on his Youtube channel, I put a tiny glob of solder on the tip of my iron and touched it to the diode's pins, and simultaneously pulled the ribbon off. All was swell until I realized that the tiny drop of solder somehow slipped through the PCB and onto the back of the diode. I guess that diode, along with the $200 I invested in it, are history... :cryyy:

Do you have a "solder sucker"? I have no idea what the real name is ;)

If so, you may be able to remelt the solder on the diode around the positive pin and suck it clean enough to get it isolated again.

Put it into a good heat sink and work quickly.

Peace,
dave

I always call it a solder sucker too. This should do the trick. I do not think your diode would die from a little spot of solder hitting it. These diodes can be tougher than you think.

I've managed to pick tiny blobs off before with a tiny flat head tech screwdriver. It seems like the solder doesn't stick to the black isolating material very well. A sucker ball may be better as long as you don't over heat the diode. I thought to use one but then weighed the option of more heat or try and scrape it off without heat first.

This can work as well. Just be very careful about "pulling" or "twisting" the pin.

i have my first phr build coming up and this has hapened to me twice with ir diodes i was wondering if there is another way of getting the pcb off.
cheers

Tiny scissors, even nail clippers.Yep I've done it.
Then I bettered my soldering skills with practice.

The vast majority of the diodes I harvest never get heat applied until I am soldering the pins to wire or drivers.

The only diodes I use the "solder blob" method with are PHR's. On all the rest I use a small set of side cutters to cut the PCB/ribbon into pieces toward the pins. Then I use the point of a sharp knife to carefully push the PCB/ribbon down. This separates the PCB/ribbon from the solder.

You are left with the whole pin AND the small solder spot that was used to attach the PCB/ribbon. This small bit of solder becomes part of the connection when I attach the wires or drivers.

Peace,
dave

ok i am using a phr. so how much solder should i place on my iron?? and i think i need to take the pcb off a bit slower
cheers

There should be enough to "join" the solder spots on the pins.

If you want some profesional help you can send the diode to me and for a very small fee and shipping costs I will inspect it, clean it up for you and make it ready to solder your driver to. I can even set your diode in an Aixiz module and set the current on your driver and solder the diode to it.
Have a good day !

I already tossed it... The mess was really really bad and it didn't look fixable, but now I'm regretting it. I tried using a makeshift solder sucker, but there was no way I could have gotten all of it out. I would go digging through the garbage so I could send it to you, Flaminpryo, but it's already miles away in a garbage truck. I'm ordering another one, and hopefully I have better luck with this one.

OUCH!

Always talk to the people here first. There is a lot of experience in this forum. If I had learned this "rule" when I was a fairly fresh NooB, I would never have destroyed a $360 diode "thinking" it was dead when it was just the battery :cryyy:

Peace,

I use a (new and very sharp) exacto knife to cut away the ribbon cable and the solder. If your blade is new, it will easily slice through the solder and leave you with clean pins and an unharmed diode.

I haven't tried this yet. Does it cut through that damnable thick "board" on the PHR as well?

Peace,
