Hi folks - Here is the Friday Element Quiz Answer:
The Question:
The pure form of this element is not found in nature. During the early
1800's this element was considered a precious metal and used by royalty. A
famous Washington DC monument has a capstone made from this element. What
element is being described?
The Answer:
The element is Aluminum or Aluminium (Al)! Aluminum is one of the most
recycled materials in the world primarily because it is cheaper to melt
aluminum scrap than extract aluminum from bauxite ore. In the early 1800s
aluminum was considered a precious metal and Napoleon had a set of
"aluminum silverware". The Washington Monument in Washington DC has a
aluminum capstone as part of its lightning grounding grid design and was
considered a significant metallurgical accomplishment at that time - the
quoted cost of the capstone was $75!. Charles Martin Hall and Paul Louis
Toussaint Heroult, who independently discovered the process of extracting
aluminum from molten aluminum oxide, had the exact same birth and death
days. Aluminum is the 3rd most abundant element found in the earth's
crust.
The winner of the weekly element quiz is Keith Calhoun, Sopark Corp and he
will get the services of Clumpy and Kloumpios for the week.
The Friday Element Quiz Arbitration Board (FEQAB)reviewed Doug's
submission and unfortunately it has been disqualified (shocking!). Doug
had stated that Sir APR Speechless had isolated Scepterium in 1815 leading
to his demise by King George IV during his knighthood ceremony. FEQAB's
review of the historical records shows that King George IV did not ascend
to the throne until the death of his father King George III in 1820. King
George IV was serving as Prince Regent in 1815.
So far Clumpy and Kloumpios have done the following:

Week 21 Amol Kane
- the boys can help me with optimization and qualification of Process
Equipment like stencil printer and wash. In their spare time they can
enjoy the fine TX summer
Dewey Whittaker, Honeywell
- the boys can stay 2 days with me and as I've always said "a man's home
is his castle, in a manor of speaking". I'll be training them in stand-up
comedy dealing with the dichotomy of Technet humor. Their names and act
will be " Grim and Stellar".
David Bealer, Watch Fire Signs
- since I will be out next week, they can take those 2 days
off. Everybody deserves a weekend once in a while.
Week 22 Phil Kinner
- assisted with ????
Week 23 Guy Ramsey, RD Circuits
- The boys arrived on Saturday as promised. Stayed at our place,
StonebridgeFarm, and helped hang high tension electric fence for my
daughter's horse
boarding operation. Sunday they helped me pull 300 hr maintenance on the
tractor, watched Caroline start (break) a horse in training, tipped a few
back by the pool, enjoyed a glorious purple sunset, tipped a couple more
while telling stories and watching fire flies . . . took it easy.
During the week they worked on the in-line cleaner, validating and
verifying the PID setups, repaired our high pressure pump for our factory
humidification system, which without Steve Gregory's care and attention,
had started to leak. Then we kicked around possible ways to keep a 600mm
by
450mm by 7.6mm, 60 layer, sequential lamination board, with 33:1 PTH,
eight DUT performance board at .4 mm pitch for 1189 Ball BGA survive
reflow,
measured z axis shift, and designed the attachment; pad, ball diameter and
stencil for the interposers. They had to rush off before we finished
developing the underfill process needed to stabilize the interposers.
Week 24 Mark Kostinovsky, Schlumberger
- The boys have been working hard and surely deserve some break. I'm
fixin' to be nice to the boys and just let them sit on my porch, have a
Texas drink, relax and enjoy our weather. This summer's been kinda cold
around here: has not even hit 40C (104F) yet.
Week 25 Keith Calhoun, Sopark Corp
- assisted with ????
Everyone have a safe week!
