39 plates (out of 48) were fired with metal layer 2. Of these 18 have so far 
been probed and ALL OF THEM HAVE SHORTS between metal 1 and metal 2. The 
dielectric between the layers was printed only twice instead of three times
as is more customary, which could explain having shorts, but we think that 
there may be an additional problem to cause so many shorts. 

The plan of action is as follows. The 9 plates on which metal 2 has not been 
yet added will get a third dielectric print before metal 2. If after this 
the problem goes away, another 39 plates will be started from scratch up to 
this point. and processing will continue with a 1-2 week delay. 
If the third dielectric does not solve the problem, further investigation 
will be necessary. One obvious thing would be to try a different dielectric.
In the mean-time Carl and Amy will keep investigating, and PMC will also 
seek a solution on their end.
