Place a break away between the 2 boards.  Rout the "U" leaving a tab
each side near the leading edge to be jump scored.  The center gets jump
scored past the connectors and just runs out into the breakaway.

Subject: [TN] panellisation query

Hi,
   
  This is regarding the panellisation of the PCB.  I have attached the
pic here and if it doesnot come attached with the mail, then pls take a
look at Steve's homepage.  I am requesting Steve to help me upload it on
his homepage.
   
  I am looking for a 2-up panel along the longer edge. The direction of
flow is as indicated.  The concern here is that the bottom edge of PCB
is having a cut-in portion. Need advice as to how can i route the PCB if
i just want to have V-groove? Will it be sufficient and reliable as to
not have issues during manufacturing? The PCB is still attached to the
raiings on the other two ends.
   
  Or 
   
  Do i need to have combination of V-grrove and mouse bites to have the
panellisation?
   
  Or
   
  If i rotate the PCB by 180 degrees, then i can have a linear V-grrove
panellisation. But, will this affect the cycle time on the placement by
SMT machine as all components would need to be rotated by 180 degrees?
Will it have an impact on reflow?   Because the other side as shown
shaded is not having any component.
   
  Thanks in advance for all your valuable inputs.
   
  Rgds
  Prashant
