Gary,
        Here are some answers to your questions:
The overall singulated unit size is 1.3" by 0.4".  There are 4 chip caps
per side and they are all the same part number.  They each measure 0.25"
wide by 0.23" long termination to termination by 0.09" tall.  There are
also two connectors on each board.  There are score lines on all four
sides of the part and the score lines are about 0.02 to 0.035" from the
solder joints.  We have separated these units with our 'pizza cutter'
and feel there is no mechanical damage but the customer won't accept
this for some reason.  We operate on the strict policy that the customer
is always right and don't question their judgement.  This is great for
customer service-sales but very tough for manufacturing.

Wade

        Wade,
            I can't answer your question on laser cutting.  I do have
some questions for my on edification, if you
        have time to respond.

        How were the assemblies with the broken caps mechanically
separated?
        What is the type of capacitor?
        What  is the package size?
        What is the distance from the damaged parts to the score line?
        Is the long axis of the part parallel or perpendicular to the
score line?
