Testers need a little R&R

Many engineers use check standards to verify equipment against a known quantity. Periodic calibration also helps.

For more, see my article Test your testers for R&R.

This may look endless and adds lots of unnecessary cost.

It does not have to be 100% bullet proof. One needs to consider product, its application and to what extent test is to be done and what can be tolerance for above described probable fauls.

Prevalent industry test procedure and calibration requirement suffice most applications. But yes, if you going to send your payload in space critical mission, go further and spend all money required.

ATE's need calibration
roshan shanbhag   10/17/2013 5:52:19 PM
With more and more complex parts coming out, Testers used to test these parts have to be calibrated periodically against a known standard and preventive mantenance must be done to ensure Quality. Calibration period may be once a month, once in 6 months or may be once a year or so depending upon the manufacturer's specifications. Usually the tester companies provide CAL boards and associated software to the customer ( companies ) to run CAL and checkers/diagnostics on the tester.

ISO Conformance no big deal

When time came for Calibration we had a test station sent to us from the NRC, (National Research Council) in Ottawa, Canada. This units calibration was tracable to the international standard wherever on earth that was. If anyone who was our client, ISO Auditor or similar wanted, he/she could question the reality distorted bureaucratic bubble that is Ottawa. Most clients and auditors choose to be happy with our record keeping rather than risk being lost in that alternate reality. Kidding aside, the calibration of some 200 DMMs, 50 Scopes and the various ATE's on the production floor only took a week of a technician's time( no enginneer required) on a part time basis as production coudln't be halted. The only problems we had were the engineers in the labs when we walked into their lair and said we were taking their test gear. Of course we were in riot gear and had pepper spray.

NEXT UPCOMING BROADCAST

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
