Rob,

The only document regarding manufacturing practices, is GR-78-CORE, 
"Generic Requirements for the Physical Design and Manufacture of
Telecommunications Products and Equipment", (Whew! That's a mouthful!).

It doesn't go into burn-in. It is mainly from the printed circuit board
design
(solder mask, conductor material finishes, noble metals, etc.) and assembly
practices.

Subject: Bellcore Production Requirements



All,

I have been asked by my supervisor to find out if there is a Bellcore
(Telcordia) specification for production procedures and practices.  I know
there was one at one time but am not sure if it remains.

The question he asked me was "Does the Bellcore specification for ambient
temperature change during burn-in of equipment, that will be sale to a
customer, limit the change to .5 degrees Celsius per minute?"  I know the
requirements for GR-63 but am wondering about manufacturing requirements.

Thanks for your time,

Rob Graff
