Solder Paste Recommendations.

Last time I bought solder paste, I just ordered from Amazon.  I usually order from Howard Electronics...

I have a hot air tool but I have never actually used it.  I guess I just don't do much repair work.

For new construction, I use solder paste and a hot plate or modified toaster oven.  Both work well.

I also simply apply paste to both pads of a component and position it.  Holding it with tweezers, I just use a soldering iron to heat and flow the solder.

For drag soldering, I use flux.  Turns out that link above contains a 'kit' part way down the page.  It adds flux and solder wick.

Considering the cost of the PCB along with the components, I can't get too concerned about the cost of solder paste.  It's insignificant in the overall scheme of things.

Thanks for the Krud Kutter suggestion, I picked up a bottle from my local home hardware.  I expected it to not work but it really does work well...

Most people that try it tell me they like it and it works great if your not looking for instant result's like you get from a chemical,I find it's mainly people that hate eco friendly stuff that don't like the Krud Kutter or people that have no patience.

If you INTEND to clean the board, use WS (Water Soluble) paste.  It works better than NC, in my opinion, and washes off easily with either water or solvent.

Except that, as others have explained in detail in other threads, without a high quality ultrasonic cleaner and well defined cleaning regimen, you cannot be certain that you removed all traces of flux, and residual water soluble flux is extremely damaging in the long run. For that reason, using water soluble flux is highly unrecommended for home use of any kind. (And even in professional use, there are some applications where it is categorically prohibited, like stranded wire.)

@BSon - can you talk about your stencil design - opening, thickness, etc.? The joints look beautiful!
