The combination of increasing quality
requirements, year over year cost reductions, and just-in-time part delivery all
contribute to the increasing need for end of line (EOL) testing. EOL testing is
performed on both complex systems like assembled transmissions and simple
components like switches. While some testing can be accomplished with simpler
measurements, it is typical for an article under test to require high quality
A difficult task in EOL system development is
the definition of a robust measure to differentiate between good and bad parts.
The measure can either be a single quantity like acceleration or more complex
like the combination of several sound quality factors. In any case, it is
necessary to start with reliable data from a system that can easily be
incorporated into the test stand, along with the PLC elements that control the
stand and the marking of component pass/fails.
For this type of testing an entry-level
MICROQ system with its included IVI driver
provides the balance of high quality data and affordable system price. Reducing
system options, like using a MICROQ
without a built-in battery and Wi-Fi, does not diminish the MICROQ’s capabilities and helps to deliver a
budget-friendly test stand.
