(NHK World (Japan))   In today's news flash, lightning strike ruins two weeks worth of semiconductors by knocking out the one power line to the plant in midst of production. God DRAM it   (www3.nhk.or.jp) divider line

Could be anything from HDD controllers, to automotive CPUs, to Apple SMCs. Time to play the semiconductor shortage game again!

it will magically somehow affect all of them, for years to come.

In other news GPU prices skyrocket again as sources cite power outage at semiconductor plant.

Oh man...  yeah a factory-wide power outage would be really bad in any semiconductor fab.  Bad bad bad.  Tools running lasers, tools doing precision work, robots moving wafers around...  tools doing things like physical vapor deposition using (electric) cryopumps and (high power) magnetrons.  Times say 500 steps being performed by different tools in that fab.

They certainly scrapped a lot of that day's product, with possible ripple effects to other lots.  Sometimes a lot gets scrapped because it sat around too long and got exposed to humidity, or to the atmosphere...

A UPS could have saved them millions of dollars. Whoops.

I didn't know their sales director was Ororo Munroe.

Those bring their own failure modes in addition to the extra cost. It's not an automatic win.

UPS's aren't perfect, therefore they suck and shouldn't be used. Flawless logic right there.

Install a $50MM factory-wide UPS to maybe save $20MM worth of product. UPS Salesman of the Month right there.

You only need a UPS capable of sustaining the factory for a short period of time while you shut stuff down without losing that much money. And it's not protecting you from a single power outage but many. They'll install one after this happens again in a year.

Able to generate megawatts of sustained power on the drop of hat? Have you specced out the costs of such a system, subby?

Power companies never guarantee 100% uptime. With no protection you're guaranteeing that this will happen.

/'Subby' means the person who posted the link, not the person you're replying to

Yup. But balance that risk against the cost of such a system. The math almost never works out. Better to invest in the original power source and mitigate risk that way.

Power outuages are rarely caused by generation issues. More common would be wind, construction accidents, and squirrels.
