Phil,
My original question still remains unanswered. Will there be any problem if
the leads (not component body) are resting on the board surface?

As we do not want body of the resistor of 1/2W and above on the board, I
just want to make sure that I am OK with the LEADS of the caps resting on
the board.

Guy,

Frequently we have large caps mounted on High Voltage Multiplier boards or
Power Converter boards and they always seem to have flimsy leads.  One of
the best solutions has been to use RTV as a method of bonding and
stabilizing the caps.  An alternate method is using a Ty-Wrap around the cap
through the board.

Not a good idea. These type components are designed to have the component
body resting on the board. Lead connections to the component are quite
fragile.

Guys,
Do you see any problem in having axial PTH capacitor's leads lying on the
board surface? I have a board with cut out in it
and has two holes across the cut out. Bec' of the height restriction on the
board, we want this axial cap's leads rest on the board leaving body hanging
in the air across the thickness.

I hope you are getting the picture here. Please let me know if you see any
problem or I should be aware off.
