Hi Inge!
My web page is still up, and I'll still post pictures. After all, I created
this web page for us "Technetters". It will always be here for us.
Looks like you had quite an adventure! I don't know if I would have torn
into the dash the way you did. You are quite brave! I've taken your photos
and put them into one *.pdf file and added my own captions. It's here:

I wonder how many other Volvo owners have experienced the same problem?
Looks like the board was conformal coated, was it? Also looks the board was
wave soldered except for that big black right angle connector which might
have been hand soldered. I wonder if the lead that had the solder problem
may have been re-reflowed when the connector was hand soldered? I'm think
that because that lead is connected to a big fat trace close to one of the
connector leads and may have got a bunch of heat transfer when the connector
was soldered in. It probably had enough of a solder connection to pass test
before it was shipped, but nobody spotted the bad solder joint. Anyways GOOD
job!
Well, I went back and picked-up my personal stuff from work today. Got my
layoff packet from HR. I did get two weeks of severance pay which is
standard for the company. I wasn't expecting anything, so that was a plus. I
did have a good conversation with the operations manager who was the one who
called and told me that I was being laid-off. He told me that it was one of
the crappiest phone calls he had to make in quite some time. He said that he
hated to call me while I was home on vacation, but he's always been up front
with me, and wanted to let me know as soon a decision had been made. I think
I understand where he was coming from. The conversion was good, and we
parted on very good terms, he said that when I need a good reference in my
job search he will be more than happy to speak with whoever I need him to.
That was nice.
I have a picture that I want to post. During my drive back to Tulsa, I was
on interstate-40 heading west between Nashville and Memphis, when I came up
on a long line of motorcycle trikes (Harleys and Goldwings) cruising
together. I came up on one very unique one that was towing a very cool
trailer. I grabbed my trusty Blackberry Pearl and snapped a picture of it in
the lane next to me while I passed it...VERY cool!
