One of the things we try to do is run test material on a piece of equipment 
we plan on buying, perform SPC, and look for a Cpk of 1.3 or better.  This 
means that the equipment must be available for use, material available in 
quantities that allow SPC, etc..  It results in a level of expertise (since 
the machine must be programmed for your test piece.)  It can be tied to the 
installation and training of the device.  And you can tie acceptance of the 
equipment to the SPC performance.

A reputable house with good product should be willing to support such 
activity.

Hope this helps.

Subject: Guidelines on ordering electronic mfg equipment
Date: Thursday, May 01, 1997 12:41PM

I am seeking information on guidelines on what is important in selecting
electronic mfg equipment.  I know each type has specific things important 
but
in general is their some info available to help ask proper questions to an
equipment mfg or for a manager to review in house engineering specifications
for outside subcontracting of a piece of equipment?  Some things come to 
mind
ie:  throughput,flexibility,programming ease, repeatability,etc.

Would appreciate any help you may provide.

Thank you
