     I suggest you contact several of the SMD process equipment
     manufacturers and ask each one to list what they believe are the
     complete list of process variables; it's surprising how much expertise
     some have.  Then ask them (or other users) to rank them using Pareto
     analysis it's a relatively quick & simple process.  From this you can
     identify which are the major contributing factors to the processes and
     include them in your audit.

     Regards Iain.

I am working on a project to establish a process audit program for the
SMT line at my company.  I want to know what is the strategy for other
engineers, such as the audit area and it's associated parameters.  I
think for each machine there is  a lot of variables to measure against.
For instant for the stencil printing process, one can measure the
hardness of the squeegee, the speed of the squeegee, the angle of the
squeegee, temperature and the humidity inside the printing area, the
viscosity of the paste, thickness of the stencil....the list can go on
and on......some of these variables may not be a critical issue of the
process.  Collecting  these extra data means spending extra time and
money for nothing.  Therefore I would like to ask the professional in
the fields to help me to define what is important and what is not for a
process audit program.  Thanks.
