Ed is the winner, but he got to share the glory with Joyce. It's a SEM
image at 2 kV, shows a very hard nickel plating (700 HV) which caused
problems when we bonded with 125um aluminum wire. The 700 HV hardness was
measured at a 25 gram load. With a 200 gram load, the hardness is 250. You
can see how the built in stress starts microcracks (to much brightners, not
necessary for ENIG, which the chinese did not know). Furthermore, it's very
coarse, about Ra=10um !). Joyce guessed goldplating. I would reject such a
gold plating surface. But she got close enough.
The dark squares are caused by the electron beam, when looking at various
magnifications.
Trumpets and horns and bagpipes and the mass's applause for the
couple.....taraaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaamtaram-
toooooooooooooooooooooooooooooooooooooooot!
Sharp eyes, I'd say. Very good!

>>who consider themselves unlucky are more likely to believe in
>>superstitions associated with bad luck.
>>
>>"Their beliefs and behavior are likely to be part of a much bigger
>>worldview," he said. "They will believe that luck is a magical force and
>>that it can ruin their lives."
>>
>>Wiseman found that one quarter of the 2,068 people questioned in a 2003

>>thus more prone to have accidents. In other words, being afraid of
>>Friday the 13th could be their undoing.
>>
>>So how did Friday the 13th become such an unlucky day?
>>
>>Dossey, also a folklore historian and author of Holiday Folklore,
>>Phobias and Fun, said fear of Friday the 13th is rooted in ancient,
>>separate bad-luck associations with the number 13 and the day Friday.
>>The two unlucky entities ultimately combined to make one super unlucky
>>day.
>>
>>Dossey traces the fear of 13 to a Norse myth about 12 gods having a
>>dinner party at Valhalla, their heaven. In walked the uninvited 13th
>>guest, the mischievous Loki. Once there, Loki arranged for Hoder, the
>>blind god of darkness, to shoot Balder the Beautiful, the god of joy and
>>gladness, with a mistletoe-tipped arrow.
>>
>>"Balder died and the whole Earth got dark. The whole Earth mourned. It
>>was a bad, unlucky day," said Dossey. From that moment on, the number 13
>>has been considered ominous and foreboding.
>>
>>There is also a biblical reference to the unlucky number 13. Judas, the
>>apostle who betrayed Jesus, was the 13th guest to the Last Supper.
>>
>>Meanwhile, in ancient Rome, witches reportedly gathered in groups of 12.
>>The 13th was believed to be the devil.
>>
>>Thomas Fernsler, an associate policy scientist in the Mathematics and
>>Science Education Resource Center at the University of Delaware in
>>Newark, said the number 13 suffers because of its position after 12.
>>
>>According to Fernsler, numerologists consider 12 a "complete" number.
>>There are 12 months in a year, 12 signs of the zodiac, 12 gods of
>>Olympus, 12 labors of Hercules, 12 tribes of Israel, and 12 apostles of
>>Jesus.
>>
>>In exceeding 12 by 1, Fernsler said 13's association with bad luck "has
>>to do with just being a little beyond completeness. The number becomes
>>restless or squirmy."
>>
>>This fear of 13 is strong in today's world. According to Dossey, more
>>than 80 percent of high-rises lack a 13th floor. Many airports skip the
>>13th gate. Hospitals and hotels regularly have no room number 13.
>>
>>On streets in Florence, Italy, the house between number 12 and 14 is
>>addressed as 12 and a half. In France socialites known as the
>>quatorziens (fourteeners) once made themselves available as 14th guests
>>to keep a dinner party from an unlucky fate.
>>
>>Many triskaidekaphobes, as those who fear the unlucky integer are known,
>>point to the ill-fated mission to the moon, Apollo 13.
>>
>>As for Friday, it is well known among Christians as the day Jesus was
>>crucified. Some biblical scholars believe Eve tempted Adam with the
>>forbidden fruit on Friday. Perhaps most significant is a belief that
>>Abel was slain by Cain on Friday the 13th.
>>
>>So, what are triskaidekaphobes to do?
>>
>>Dossey said "practical" cures are as simple as learning to refocus one's
>>thoughts from negative feelings to positive. His mantra: "What you think
>>about, you begin to feel. What you feel generates what you do. And what
>>you do creates how you will become."
>>
>>In other words, those stricken with negative thoughts about Friday the
>>13th need to learn how to focus on pleasant thoughts. Those, in turn,
>>will create pleasant feelings that make one's fears less overwhelming,
>>according to Dossey.
>>
>>"They haven't lost their mind. They've lost control of their mind,"
>>Dossey said of triskaidekaphobes. "They are focused in the wrong
>>direction. In their mind they have a big, large, looming picture of
>>something horrible that could happen."
>>
>>Wiseman, the University of Hertfordshire psychologist, offers similar
>>advice to those stricken with the fear of Friday the 13th.
>>
>>"They need to realize that they have the ability to create much of their
>>own good and bad luck," he said. "And they should concentrate on being
>>lucky by, for example, looking on the bright side of events in their
>>lives, remembering the good things that have happened, and, most of all,
>>be[ing] prepared to take control of their future."
>>
>>Folklore offers other remedies, however. One recommendation is to climb
>>to the top of a mountain or skyscraper and burn all the socks you own
>>that have holes in them. Another is to stand on your head and eat a
>>piece of gristle.
>>
