T.G.I.F. Everybody!

    I was wondering if anybody has ever done any kind of time studies, or has
a good figure to use to plan how long it will take to manually place a board?
I know it depends on what kind of components are on the board...you most
definitely can load a resistor a lot quicker than a QFP, but I've been
"butting heads" with someone who thinks they can apply the same general time
standards that you use to figure the time it would take to load components in
a slide line...basically I said horse pucky, it's  a whole different ball
game. You're not handling the components with tweezers in a slide line, and
you don't have to worry about smearing solder paste in a slide line among
other things. I said that anywhere from 75 to 125 components an hour isn't
unreasonable at all...anyways, I don't want people to rush thru handloading a
board. It's very easy to create enough rework
that would negate any time you'd be saving by rushing through it.
Any thoughts?

Tia!
