    Kindle Edition of My PCB-RE Books

    The current CoVid-19 situation has many countries imposed restrictions on import and export of non-essential items. Similarly, Amazon has limited its delivery service of printed books overseas. After much deliberation, I decided it's time to go the ebook route. After reformatting the layout of...

    PCB Reverse Engineering

    That's a pretty good attempt! I wrote a trilogy to my PCB-RE book collection, PCB-RE: Real-World Examples and got it published in February 2019. Your post came a bit late or I would have asked you to be one of the contributors. You can find it on Amazon in paperback and ebook formats...

    What is PCB Reverse Engineering

    @Mattylad That's quite an achievement you have in reverse engineering a board of such complexity and pin count. I've done quite a bit of it myself for the last 15 years and have written a book on this subject which was released in Amazon on February 28 this year! PCB reverse engineering is an...

    Difference between AGND and DGND

    Hi Tom Some manufacturers provide chip topology and PCB layout consideration information in their IC datasheets and these should be useful for your consideration. I'm not a PCB designer so I can't advise you on the other issues that you raised. Perhaps some other in the forum can help. Best...
