***New Question***
If poison goes out of date, is it more, or, less poisonous?
And, yes, I know it will still be poison, more or less. |

Yes, 1/81 is 'one eighty-first'.
Re poison ... depends on the poison. Some break down and lose potency (but no one here would know about that, right?). Others remain lethal to the end. ;) |
how about iocaine powder?

That requires slow, careful acclimatization, patience and appreciation needed; then you defeat the egotist (inconceivable!!) and win the Princess.

***New Question***
Why are circuit boards (especially the older ones) green?
|
That's solder mask, protecting the circuitry (etched copper) from scratches and from solder wicking and shorts and corrosion. When producing circuit boards (I was QA supervisor at a high tech board manufacturer back in the day) the copper layer is etched into the circuitry pattern, then solder mask applied, then sent through a solder bath system with air knives to coat the exposed copper surfaces in solder, those surfaces being either through-hole or surface mount areas for components (typically a tin/lead alloy.) The mask prevents a big old mess of solder covered copper for that process.
That's it in a nutshell anyway. The green mask isn't always used: we made some boards coated in gold plating, and some the exposed laminate was left that way. Depends on the application and intricacy of the board. Don't know why green is the color, but when I worked in the industry it was all green. |
When working with circuit boards, you never get out of the shop. It's the only green you get to see.
