Consider placing the arrays in process carriers for SMT process.  It would
require adjustment to your reflow profiles for the added mass, but with an
.062" thick PCB it shouldn't be a big issue.

Subject: [TN] Injury by array

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?
