So I recently had a really specific problem involving a SL stainless steel host. The leads had torn off of the diode mostly due to my poor soldering job this seems like a simple fix but I had used thermal adhesive on the heat sink and the host body meaning I could not easily remove the sink or diode module so here is my solution to this “bricked” host.
Now my first and admittedly stupid attempt was to re-solder the leads back which I did by removing the diode module back half then trying to reach with my solder iron the result was I got solder all over the diode pins as seen below.
The only solution that I could think for this was unfortunately a hammer.
So I took a screwdriver and hammer to the diode and tried my best to avoid the diode lens and surprisingly the diode came out relatively unharmed.
Now getting the solder off the pins it was as simple as a blowtorch, flux, and some good pliers
After pressing the diode into a new module it was ready to be de-soldered
The first hit with the torch loosened the solder and I was able to move it off one pin with the nose pliers.
Be careful to not use the torch for longer than a few seconds to prevent overheating
After getting the solder off one pin leave the diode to cool for at least a minute the using the torch, light flux and pliers carefully loosen and remove the solder glob without damaging the pins.
After the solder glob was removed resolver the leads on and use heat shrink tubing then apply thermal paste the the bottom on the diodes then seal the module back together.
Maybe not the most elegant approach and probably not a very common problem but I though it might be useful to anyone in the future who might also have a bricked host.
Beamshots of after extraction cuz beams are cool
