I can not say that I am particularly impressed with the ASME including what
they do in the electronic packaging arena. Organisations like the IPC have to
work with the resources--its members volunteering time--they have. As
industry organisations go, the IPC is better than any other I know; that does
not, however, make it perfect. Just think about it, where would the industry
be without the IPC standards and guidelines? When the industry does not
publish, or even produce, their experiences and test results, where are the
data suposed to come from. When did you  last see somebody publishing a
failure? Ten, 15 years ago the industry had flourishing laboratories that
produced and published data; in the 1980's Bell Labs had upwards of 50 people
at IPC meetings. All these labs are shadows of the former selves with the
bean-counter's down-sizing (it's good only for consultants).
So, I was not knocking the IPC, but asking for more data from the industry so
the documents could be more grounded on them rather than only consensus.
