To My Readers



If this is the first time you're visiting my blog, thank you. Whether you're interested or just curious to find out about PCB reverse engineering (PCB-RE), I hope you'll find something useful here.

This blog contains many snippets of the content in my books to provide a more detailed overall sampling for my would-be readers to be better informed before making the purchase. Of course, the book contains more photos and nice illustrations, as evidence from its cover page. Hopefully, this online trailer version will whet your appetite enough to want to get a copy for yourself.

Top Review

I started doing component level repair of electronics with (and without) schematics more than 40 years ago, which activity often involves reverse-engineering of printed circuit boards. Although over the years my technical interests have shifted into particle beam instrumentation, electron microscopy, and focused ion beam technology fields, till this day——and more often than not——PCB repairs have returned multiple multi-million-dollar accelerators, FIB, and SEM instruments back to operation, delivering great satisfaction and some profit.

Many of the methods described by Keng Tiong in great details are similar to the approaches I've developed, but some of the techniques are different, and as effective and useful as efficient and practical. Systematic approach and collection of useful information presented in his books are not only invaluable for a novice approaching PCB-level reverse engineering, but also very interesting reading and hands-on reference for professionals.

Focus on reverse engineering instead of original design provides unique perspective into workings of electronics, and in my opinion books by Keng Tiong (I've got all three of them) are must-read for anybody trying to develop good understanding of electronics——together with writings by Paul Horowitz and Winfield Hill, Phil Hobbs, Jim Williams, Bob Pease, Howard Johnson and Martin Graham, Sam Goldwasser, and other world's top electronics experts.

Teardown: Portland 2018

The annual Teardown Convention was held in Portland, Oregon this year and had just ended. It is an event where hackers, hobbyists and designers converged and share their ideas, discoveries and inventions through talks conducted in various rooms equipped with the necessary AV equipment:


Portland, Oregon is the hometown of Joe Grand the kingpin so it's no surprise he graced the event with his presence and presentation. What aroused my interest, however, was a talk given by Jeremy Hong, a cool young dude from Wright State University who runs his own business. In his first talk at the convention, he actually recommended my book PCB-RE: Tools & Techniques to the audience:


How cool can that be? In appreciation, I tweeted him:
Thanks, Jeremy, for recommending my book at your Crowd Supply Teardown talk. I owe you a big one! ;)
to which he replied:
No problem! It’s an excellent book and it really needs to get out there.
Since he's also into PCB reverse engineering, I asked if he's interested to write a chapter for my third book, and I got more than what I bargained for:
Definitely! It is an honor. I think I may have a few people in mind (that may be able to contribute to the book as well...)
Well, looks like there is hope for the trilogy book after all...
