Hey all-

        Engineering has come up with the idea of replacing some bi-level LEDs with
smt LEDs and attaching light pipes.  These Dialight light pipes "press-fit"
into drilled holes in the board.  I am not sure if we are trading one
process step for another.
        We currently selectively wave solder the pth LEDs, but there are some
resistor networks making the pallet openings a little hairy...but it is
feasible as they are.
        My question is:  how tight do these light pipes press in?  Is anybody else
doing this?  Do I need to heat-stake these things?  If so, it doesn't sound
like any advantage from a manufacturing point of view.  If not, is it easier
to press these in than place pth parts, clinch and wave?
        I am not completely sold on this idea.  Thanks all.
