While Intel Corp. has seen major benefits from its facilities equipment predictive maintenance program, the company is also seeing payoffs in an unanticipated area, says Mick Flanigan, predictive program maintenance manager at the companyās Hillsboro, Ore., facility.
Intel is not only using its handheld condition monitoring and vibration analysis tools for predictive maintenance on existing equipment, but is now also using the equipment for acceptance testing. Tests on newly purchased facilities equipment are performed before and after installation, prior to warranty start dates, to ensure that the equipment meets Intelās manufacturing standards, Flanigan explains.
The advantages are clear. If new equipment is brought online without meeting Intelās specifications, process abnormalities can and do occur. Undue vibration in facilities equipment can trigger shifts in chip-making equipment calibrations. Further, says Flanigan, āweāre driving our vendors to give us better quality equipment. Weāre tired of having a warranty that lasts a year, and then two months after the warranty expires, we find ourselves replacing the whole piece of equipment because itās destroying itself,ā he declares.
The new acceptance testing procedure has been used on a couple of plant start-ups, says Flanigan. āNow, weāre not tagging equipment as ours until it meets our vibration criteria, our infrared criteria and many other processes as well,ā Flanigan says. āWhen we bring this equipment into our facility, we have better assurance that itās going to last beyond the warranty. Surprisingly, this is the area of the program where weāve seen our biggest hard cost savings.ā
