Ian -

I have not been able to identify any differences between this part and
any other part being run on the line. We have no copper in the rail to
expose, the provided offending panels are straight and smooth, no signs
of router chatter or tooth. As to the reason this is a design issue - I
was not invited to the meeting when they were determining cause and
fault - Such is life.

What makes this board different from the 'safe' designs and how was it
established that this is a 'design' issue?  Assuming that operator
handling is unchanged.  Which part of the board is causing the injury?

Oh wise and wonderful members of tech net -

We have had to incidents in the past six months where assemblers have
been cut while handling assembly arrays (2-up panels) for one of our
products. This has elevated the issue to "Panic Mode" due to the
involvement of EHS&Q (environmental health, safety and quality). As the
designer of the array I have been given ownership of the issue and am
task with resolving it.  After 20+years of handling boards and arrays I
have never been cut, so I am unsure as to what if any corrective action
can be taken to prevent future injuries.

The specifics on the arrays -
10.5" [267mm] x 12.0" [305mm] x 0.062" [1.6mm] thick
2 - up for 4.7"[119.3mm] x 9.2" [233.6mm] PCB
Minimum rail 0.38"[9.5mm]
Tab Route and Retain (mouse bite)
Injuries occurred during loading of the solder printer and during slide
line operations for post reflow assembly. 

Any suggestions on what to tell our production group?
