The Chinese Lunar New Year (CNY) is just five days away and spring cleaning is currently underway in my house. Amidst the bustling activities in preparing for this festival, I decided to start writing Chapter 9 on Other Techniques of PCB diagnostics. My engineer friend is tied up after coming back from a long holiday and can only give me the materials I need after the CNY. Oh well...
What are the other techniques that I will be exploring? For sure, JTAG is one of them. Another two more will be AOI and AXI, and I will include a comparison of these two. There is something about virtual instruments but I've yet to decide whether to include it in this chapter.
Here's a two-page sample for Chapter 9:
Incidentally, my friend's company ABI Electronics also carries a JTAG diagnostic tool for which I've also requested for a case study. If he can provide that, it would be a good illustration to my collection of examples in this upcoming book.
I will try to squeeze some time to write during this busy festive season, so stay tune for more updates.
