[R-390] killer and mica caps

[Bob Camp]

Hi

The winding plan and the termination stuff gets designed into “the machine” (yes there’s probably one machine running
around the plant). That pretty much puts it outside the day to day control of the people running the gear or running the
plant. Either they designed / bought the right gear or they did not. 

Cleanliness matters in juts about all electronics. Unless things have changed a lot since my last visit, semiconductor
wafer grade clean rooms are not part of a normal film capacitor plant. It’s more the same level as “living room clean”. 
Yes, you can get it wrong, it’s not a massive challenge to get right. 

So, again on the same basis as the original post (management controls the process), this is not quite the same thing as making
a lot of modern components…..
