[simpits-tech] Soldering how-to

[Jim Sturcbecher]

I agree on the tools, bits and angles comments, Chris.
The guys' technique does leave a bit to be desired. And
yes, I also cut my leads after soldering with good
quality angle nose cutters; but doing this will fail you
on getting "Space-Qualified-Soldering" Certification.

I posted this video link mostly as it gives a basic
understanding as to "why" you solder with flux-cored
solder and what cleaning and tinning is all about, etc.
Most of the rest comes with practice.

Main point is keeping everything clean and applying the
iron and solder to the right points in the right order
'at and for' the right time.

Jim.

they go most of it right - but some things are flat out wrong.
1. cut your leads after your board is cooled - a min or two
2. hold your soldering iron at a much higher angle... like 60 degs.  or 
about 30 deg from vertical.
3. most of what you will be soldering will use a conical or taper tip. 
if you need a chisel tip. then you are going to solder a much larger 
part...
4. get some solder wick for unsoldering
5. get a solder pull-it vac for unsoldering
6. say away from sandpaper it leave grit on things
7. get a 'pink' eraser its good for cleaning pcbs
8. if one pink eraser is good then two is better mounted in a U shaped 
spring steel (beryllium) is good for components.
