For just straight up assembly of one-sided SMT boards (i.e. not reclaiming components from a donor board), a $30 plug-in electric skillet and a solder paste stencil from the PCB manufacturer (or patience and a solder paste syringe) works far better than it has any right to. https://www.instructables.com/Simple-Skillet-Surface-mount-S...

The hot air station is called a "rework station" because it's very helpful for rework, too.

Using a hot plate to reflow boards is fine if you already know everything is correct. Having a real hot air station is very important if you need to change any parts or even fix reflow problems.

I prefer a regular soldering iron for SMD. Below 0603 I tend to blow off unrelated components if I’m not very very careful!

So for me, a loupe/microscope and a fine SMD iron is the best option. I have some China-model that uses Hakko tips.

I been using these mini pan frying skillets for years for prototype boards. <$2. An IR thermometer with a laser is handy during the process.

And here is the cheap hot air rework station I use. <$15

You can even opt out of the stencil but I never do cuz it's much easier than not having it.

Haha I've got an old toaster oven, it works wonders for basic prototype assembly!

On aliexpress, search for "demolition heating" and there are really cheap ($5 or so?) heating plates that I believe are used for removing SMD LEDs.

Not sure why they'd need to remove SMD LEDs, but whatever.

They are "PTC" which means they top out at a certain temperature, usually 260 degrees.

I would recommend using an inline fuse holder for some semblance of safety though.

One of these, a lamp cord, some solder paste and a toothpick, and you can easily assemble SMD boards.
