Front Panel

The front panel is  0.780"  wide.

This width gives a 10 mill gap on each side between the inter-board
separation plane and the side edge of the front panel.  By definition
the component surface of the pcb is  4.07mm  from the inter-board
separation plane to its left.   4.07mm minus the 10 mil gap means that
the component surface of the pcb is  0.150"  from the left edge of
the front panel.

Measurement of assembled cards looks slightly different.  On these
cards the component surface of the pcb appears to be more like  0.170"
from the left edge of the front panel.  For the layout this implies:

   The left LED is 0.100" up from the surface of the pcb -->
   0.270" from the left hand side of the front panel.

   The right LED is 0.300" up from the surface of the pcb -->
   0.470" from the left hand side of the front panel.


The front panel is  9.065" long.

The 6U VME card is  233.35mm  tall.  This means that the 6U VME card
is  3.10mm  taller than the front panel (1.55mm top and bottom).  Thus
to calculate how far down from the top of the front panel a point
should be,  subtract its distance up from the bottom of the card from
233.35mm and then subtract 1.55mm.  Distance down from top of front
panel equals  231.8mm  minus the distance up from the bottom edge of
the pcb.

The 12 LED holes are  0.130"  diameter.

The 2 bracket mounting holes in the front panel are  body drill and
counter sink for metric  M2.5  flat head screws.   Counter sink in
from the flat surface of the front panel.



Mounting Bracket

The mounting bracket is made from  0.375" x 0.375"  bar stock.
A cut is made  0.095"  deep which leaves a  0.100"  wide lip along
the front edge.

The 3 board mounting holes are  0.140"  back from this front lip.

The 2 panel mounting holes are  0.140"  up from the board mounting surface.

All holes are drilled and taped to receive metric  M2.5  screws.



Notes from: 10-JAN-2005

- Want to cut down the left hand lip of the front panel (as viewed from
  the front) by  0.075"  to give a nice amount of component clearence.

- Measure from the left edge of the front panel  (as viewed from the
  front)  to the pcb mounting surface of the top and bottom handles
  and this is  0.163"  on the average.

- Measure the diameter of the substitute LED's and this is  0.120"
  to  0.125".

- For the first 10 cards which use the substitute LED's,  put the
  holes for them in  0.250"  from either side of the front panel.
  Use  0.125"  holes.
