Good afternoon from Spain,

In a lot of PCA’s, we have detected several cases of discontinuities in the 
inner layers –confirmed by microsections-

We would like to test the rest of the lot in accordance with the method 2.6.6 
of IPC-TM-650, but this method doesn’t specify the temp ramp to pass from a 
step to the following. Can you help us?

Thank you.

Juan
