I must admit that our move pales in comparason to the ones you are tal;king about. Nevertheless there are many frustrations, especially if the logistics haven't been well thought out. In our case we moved from a location where we were renting space within another organization to one that we own. So issues like stocking the bathrooms, kitchen, picking up the garbage and snowplowing were all new to us and someone has to look after that, but who? That is to say nothing about the responsibilty for the layout, fitting existing furniture iton that space, redeploying partitions, storage space and on and on. It didn't help that the guy organizing this first had bypass surgery and then a detached retina slap dab in the middle of all the preparations.

We are about 50% done with another 90% to go.

ICT more cost effective than Functional tests

Nice article Aubrey, thank you.  At my current company, I have found that In-Circuit-Test has become much more cost effective than a purpose built functional tester (when considering all NRE charges + test time).  Especially as you have mentioned, a micro is involved, as that is used to test signal "strings" as I call them.  We have found a 10:1 reduction in test fixturing development costs at best, and at worst, a 1.3:1 reduction (depending on complexity).  The key is to design the board  (PWB) with enough "targets" for the bed-of-nails to cover enough nodes.

Thanks for your kind words and for sharing your experience.

I don't know how you found this blog since systematic searching of the EE Times blogs is well nigh impossible, and to my surpirise has actually even got worse, but I digress.

This blog was one of three- the other two are here

Part 2

Part 3

Might I be so humble as top suggest you take a look at these associated ones- you may find them interesting as well

Thanks for the other links, I'll check it out.  I found your blog in the right column when I open the main EE TImes web page.  I check out EE Times every morning (M-F).  You're one of the authors I check out when ever I see a new entry.  --Best Regards.

 You're one of the authors I check out when ever I see a new entry.

Stop, I'm blushing!

But if you're inetersted. as a result of the reorganization of content on EE Times, I relocated to Embedded.com earlier this year. It is much easier to point to my blogs there, see Without A Paddle

I also made a contribution to Planet Analog until it reorganized at about the same time. Planet Analog allows me to group my output here
