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.

Personal Contemplation on My Writing Journey

Back in 2013 when I started out to write my first engineering book, The Art of PCB Reverse Engineering, while working part time, I had only one thing in mind—to document my own experience in this niche skillset which I've developed over the span of 15 years. After two years of grit and sweat, the book finally went online in all Amazon bookstores.

Little did I realize that it not only created a stir in the PCB-RE community because no one had ever attempted putting this much coveted topic into print, it launched me further into deep waters as readers prodded me on to give the PCB-RE subject a more thorough treatment. Of course, besides being delighted, I was painfully aware of my own inadequacy since my expertise lies mainly in the manual method, although I had limited exposure to semi-automated approach using the clip-and-learn equipment in my workplace, and explored with industrial equipment provider on the flying probe platform as a plausible alternative which, unfortunately did not materialize due to cost justification.

After few months of extensive research and intensive read-ups, I was convinced that if I were to have any success in writing a sequel book addressing other PCB-RE techniques, I would need the help of engineers with the relevant experience and knowledge. One of the first person I looked up was none other than Joe Grand aka 'Kingpin', the legendary hardware hacker of the Boston-based hacker group L0pht Heavy Industries who achieved mainstream popularity at the age of 33 after appearing on a Discovery Channel series Prototype This! In all honesty, I was just trying my luck but never in the world did I imagine that Joe not only responded to my email and request, but heartily endorsed the book in his own website! So two years after 'The Art' book was published, PCB-RE: Tools & Techniques was released with much anticipation, albeit without any fanfare. But it made big waves with the PCB-RE community, thanks to the many well-known contributors who supported my daring endeavor.

I would have easily called it a day after the dust settled over the initial excitement but somehow the nagging feeling that a third book—a trilogy, would be fitting to complete the PCB-RE reading experience, something of a practical nature to show those picking up this skillset how it's really done in the real-world. And so, PCB-RE: Real-World Examples came into being a year later.


With three PCB-RE books now available to any aspiring PCB-RE engineer wannabe, perhaps one question remains to be answered—which book should I start first? Well, I'll leave that to another post for now...
