Two Questions

[David Dietrich]

Greetings DE KC9EHQ,
 
I am a little over 1/2 way through my KNB1 before I start on my anniversary present (K1).  
 
My lab is set up in our basement where I have my table in front of a window.  I do have a small oscillating fan blowing air out the window.  Is that enough to keep the solder fumes to a minimum, or do I need a window fan?  I will only be working on this for about 2 hours/session until the radio is completed.  I'd work upstairs at the kitchen table, but the XYL doesn't want this stuff upstairs.  Any suggestions as to what others have done would be helpful.
 
My other question concerns the three capacitors on the bottom of the Rev. C board.  Are they supposed to be mounted so they are lying flat against the board as opposed to the way you would mount them if they were on top?
 
Any help is always great!
 
Thanks & 73,
 
David

I've worked at locations that the folk who do soldering nearly their entire shift have a fume hood to take care of that problem.  Of course for 8 hours/day 5 days a week every week, that seems like a good thing to do, and may be required by OSHA for all I know.  I'm currently working at a small startup company and the guys who do lots of soldering don't have fume hoods, but they do use a small muffin fan to blow air across the bench.  The benches are lined up back to back, so they can't blow it out the back of the bench into somebody else's area, but there is generally nobody working on the workbench next to them, so that is why it blows across.

Rather than having the small oscillating fan blowing the fumes toward you try to have it blowing to the side or away from you.  It should be fine.  Having not used a fan at home myself when I built my K2 and extra modules I noticed that my lungs were a bit sensitive & I coughed more than I should have for several hours afterward.  Since I worked on the K2 in the evenings for several hours each night and until I went to bed the extra coughing didn't allow me to get to sleep very well.  Watch for those sort of signs -- listen to your body -- and adjust accordingly if necessary (do what I say, not what I do).
