Hello TechNetters,

 

Here is my dilemma:  Because of an issue we are having with one of our
board houses,  I was reading the IPC-6012B. I found many references in
the spec that states a "production panel" may be used in lieu of the
"coupons"... (i.e. see para 3.6 Structural Integrity beginning on the
bottom of page 13 and continued on page 14).

 

What I can not find in the 6012 is how many "production panels" are to
be used.  Does it imply you have to use the requirement per Table 4-3
Acceptance Testing and Frequency Sample Index for Annular ring
(internal) to be 0.1 per Class 3?  Per this index number, per Table 4-2
requires 125 samples per 151-280 boards as we had 184 boards built?

 

How would you interpret this?

 

Thank you.
