Car Lights For Reflow Heat Source

If you only have a car and you need to unsolder some tricky surface mount components: what would you do? If you’re Kasyan TV, you’d remove your car’s halogen lights and get to town. That’s right: car lights for reflow.

When the friend of the host of Kasyan TV needed to remove some roasted toasted FETs from his motherboard but didn’t have anything for reflowing, she took some headlights and used them as an infrared source to desolder the FETs. Powered by a lab supply (although car batteries work too), the process works with 60 and 100-watt bulbs.

Now, reflowing with halogen bulbs isn’t new, and we’ve seen it done with the run of the mill 100-watt bulbs and a halogen floodlight. However, what we really like about using car lights is that they’re available everywhere and we already own some that we could (temporarily) repurpose. Now, don’t get us wrong – if you’re going to be reflowing more than just a little, there are plenty of alternative methods that don’t involve staring at “rather bright lights” for extended periods of time.

People ’round these parts can’t seem to get enough of reflow: from open source reflow oven controllers to reflowing with a hair straightener we’ve seen quite a bit. If you’re new to the reflow arena, we’ve got zero to hero: reflow style just for you. And if DIY at home reflow isn’t intense enough for you, we’ve got next level reflowing as well.

Homebrew Solder Pot Is Too Dangerous Even For Us

[rue_mohr] is building a hexapod robot, and that meant he needed to tin a whole bunch of ribbon cables with solder. Using a soldering iron for this task would take far too long, so he built a homebrew solder pot to tin all those wires quickly. While [rue] was able to get solder on all those wires quickly, we need to question his method – he used a halogen light and reflector to melt all that solder.

The build began with a recycled halogen light fixture. After taking apart the entire assembly, [rue] reassembled it into something resembling a solder pot; a concave reflector and halogen light bulb sit perfectly flat on the table, ready to accept pieces of solder.

After throwing the switch and putting a few bits of solder in the reflector, the solder pot surprisingly worked. [rue] was able to quickly tin his ribbon cables, and the halogen bulb and reflector didn’t break yet.

This is one of the least safe solder pots we’ve ever seen – the bulb could easily explode, and melted solder could come pouring out of the reflector at any time. [rue] is aware of the safety implications and make sure to wear a pair of goggles. If it works though, we really can’t complain.

Check out the video of [rue]’s solder pot (with an awesome temperature indicator light right in the middle of a pool of solder) in action after the break.
