Learning to solder tiny SMD components again - With hot air this time!

- So I decided to give SMD soldering another go but this time I used hot air with the popular 858D hot air station. I also decided to skip the cheap boring kits and had a custom PCB made. This was my first time ever ordering a custom PCB - I've always made my own in the past - and I was very pleased with what I received. JLCPCB is not a sponsor of this video, but they delivered an excellent product!

Soldering SMD with hot air definitely has its challenges - like not melting your components - but it's a lot more fun than doing it with a soldering iron. I've done some more practicing since making this video and I think I've finally figured out how to solder those LEDs without liquefying them!

This was a great watch John
Thanks, Udi! :)
15:15 what if you just bridge them? and what airflow are you using?
Nice project! Another nice addition would be 2 x CR2032 coin cell batteries and an smd switch making it portable.... why? Why not? "Just because" :)
Edit: Side question - which of the camera is your Macro one? I've been thinking of getting a Macro camera for zooming SMD and PCB stuff in general
The main issue is that the coin cell batteries probably wouldn't be able to provide enough current for all of the LEDs. Even without a resistor, you can run a single LED off a coin cell battery without blowing it. If you've got this fully loaded with 42 LEDs, it's going to struggle! As it is right now, it's already quite portable. All you need to power it is a USB power bank and most of us carry one of those around these days for phone battery emergencies.
Side answer - It's the same camera I always use for filming overhead stuff (the Panasonic GX80/85). The only difference is the lens. I'm using the Nikon 105mm f/2.8D AF Micro-Nikkor with the Viltrox NF-M43 adapter so I can mount it on a Micro Four Thirds camera. :)
