We have a similar thread for soldering stations. I’m looking to build anti-spark switches. The PCB is easily accessibly as well as the BOM parts. The only issue i’m having is getting a hold of the right tools for the job. Ideally i’d like to be able to make switches from scratch and potentially fix/replace mosphets on the vesc and other minor things.
What do you guys with more ‘small scale’ electronics experience recommend for me? A hot air station? reflow oven?
Name: CSI 853B+ Digital Preheater Station with Hot Air Rework Option
Temperature Range/Hot Air: 100-480 deg C
Comes with adjustable temperature and air speed.
But if you live in a different country like mine that has 220/230VAC not 110VAC you need to find the 220/230VAC version. And ask them if they have the right socket for your wall.
Some of the reviews:
Finding the right solder paste for small SMD rework applications was tricky, until I found this product. It’s easy to work with, and goes a long way.
Used it to solder all my SMD with hot air. This quantity is enough to do thousands of clean solder. use it and never revert back to awkward “classic” soldering
But I can’t really say anything about it yet haven’t used it yet. Its chilling in my fridge
I buy my circuits with stencil so I just apply over the stencil. If not a needle would be a great idea. Maybe the white things for your ear wax would work too? I have experienced some bridging with not using a stencil.

Yes I use a flux pen too. But I don’t think its really necessary

I have a similar one to this. I think i got it for about $100 a few years back - best money spent on DIY in a long time! Recommend you don’t misplace/lose the small nozzles to focus hot air when doing small smd work. You can also use kapton tape (sp?) to block/fence-off areas you don’t want to heat and reflow. Important to keep airflow down so you don’t reflow components you don’t want - and the lower airflow to avoid pushing those working components off their pads when replacing the defective component! The tape can help block and hold stuff in place.
