content: While I was cleaning out my phone, I came across this photo I took over 3 years ago. I thought I'd share it as at the time I'd never seen a gold packaged IC before and was intrigued by it...

content: It's a signal processor board from a military radar which is now obsolete (though still in its final stages of deployment, mainly used for training purposes nowadays). Manufactured circa 2001/'02.

content: Woo shiny!I like cards which are designed for VME and other backplanes. You can feel the quality, the engineering, the "no matter the cost" mentality in most cases.

content: Looking back at this photo I'm curious to know how many layers the board is. Might have to take another look some time.Also, the use of the gold plated pound symbol for orientation indicators (assuming that's what they're for)... seems like someone was proud of their PCB layout and wanted to go the extra mile.

content: Quote from: coppice on October 19, 2015, 02:29:42 pmYes, you're right. When I say obsolete, I refer to serviceability and limitations of the system. While I am not sure of the reasoning behind this, I do know that the company who designed it was bought out over 5 years ago.In my experience, systems which are of that age (25+ years) tend to be backup systems (if not backup of a backup (of a backup in some cases)).
