After pricing out and reading reviews for a few different solder fume extractors, I decided to try and just build my own.
Materials
- Cooling Fan from an old desktop computer.
The computer I had used two different fans, one for cooling the CPU and another for the power supply. I found the one for cooling the CPU worked much better.
- An old DC power supply.
I tried a couple different ones. Some worked well, others did not.
- Aftermarket Carbon Filters
- Solder Fume Extractor Frame
- 3" long #8-32 round head machine screws (Qty: 2)
- 2" long #8-32 round head machine screws (Qty: 2)
- #8-32 course nylon lock nuts (Qty: 4)
- Shrink tubing
Assembly:
- Cut the end off the power supply.
- Strip about 3/8" of insulation off the wires of the power supply and cooling fan.
- Tin the tips of each wire.
- Slide 1" pieces of shrink tubing onto the wires of the cooling fan.
- If the power supply has a wire with a stripe on it, solder it to the cooling fan's black wire.
- Solder the remaining wire to the soldering fan's red wire.
- Slide the shrink tubing over the soldering joints and apply heat.
- Cut a piece of carbon filter 1/2" wider and 1/4" taller than the cooling fan.
- Place the carbon filter between the cooling fan and the frame so that 1/4" sticks out on each side and the top (you want the bottom to be flush so that it sits flat and stable on a table). Then use something sharp to poke holes through the carbon filter for the bolts.
- Run the 3" bolts through the bottom of the frame, carbon filter, and cooling fan. The longer bolts will help stabilize the cooling fan.
- Run the 2" bolts through the top of the frame, carbon filter, and cooling fan.
- Use the lock nuts to fasten everything together. Do not over tighten. Just screw them on enough to hold everything together loosely (you don't want to crush the carbon filter).
