Folks, I've just downloaded my copy of the formative IPC-9151. Just wonder how many others have done the same. I cannot comment on the docuement but in one way. This seems an awsome undertaking to say the least. Not a negative comment, but this seems not only an endless task but one almost impossible due to almost daily technical advances. Having said that, it is easy to see not all of us are doing complex SMT only. Questions still arise, as they should, concerning conversion factors from thru hole to SMT with respect to reliability and cost. Damn interesting stuff and must reflect how all those 279 equations are being applied.
