And here for the Case/Safe PSU Combo itself
Step 1: Things you'll need
- solder iron (preferable one averaging around 50 watts)
- a pair of helping hands
- a flat head screwdriver
- a Phillips screwdriver
- cutting pliers (to cut the wires)
- a solder sucker or solder wick
- a fume extractor as featured on the case/safe
- a desk fan to keep me cool, ha ha ha
- a desk lamp, I was in a poorly lit area
- and last but not least, the case/safe PSU combo itself
Step 2: Make the circuit board safe to work with
The mains/reservoir capacitors are the two large cylinders shown above. Think of them as storage tanks of electricity or as the name implies, reservoirs.
To discharge them, use a screwdriver to short the two metal leads together for each capacitor. If you see a large spark, that means that the capacitor still had a large charge stored in it in the range of 110V -240V dependent on the input voltage and may have been lethal if ignored.
This is not to scare or discourage you but, handling the circuit board can be very dangerous if the mains/reservoir capacitor is not first discharged. High voltage may remain stored in the reservoir capacitor even after being unplugged for a few years. Always release any residual energy that may be left in the capacitors by shorting the two leads together. You could get seriously injured or die if mishandled. I am NOT responsible for any injuries you may receive for failing to adhere to proper safety procedures.
Step 3: Removing the wires
Step 4: Desoldering time
Step 5: Making progress
A good technique I found was to remove a little solder at a time then allow to cool slightly then go again rather than to apply full heat for a longer duration to remove the solder that will risk damage to the delicate components. This is especially true of transistors.
Step 6: Further progress
Step 7: Finishing up
Step 8: Sorting and Storing the Components
