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.

Trilogy Controversy (Part 1)

George Lucas' iconic Star Wars Trilogy was a big hit with loyal fans the world over, yet there are always critics who read the original novels by Alan Dean Foster and felt strongly that the order of screening did not conform to the actual story line depicted in the books. Lucas, of course, had his reasons to film series IV (Star Wars), V (The Empire Strikes Back) and VI (Return of the Jedi) as the classic trilogy in the pre-90s...


before going on to produce series I (The Phantom Menace), II (Attack of the Clones) and III (Revenge of the Sith) as the next set of Trilogy films.


Similarly, there are people who may be confused about my series of PCB-RE books and perhaps questioned the need for a trilogy instead of just one volume. I'll have to admit that when I first started out to write about this topic, a trilogy is far from my mind, let alone a sequel book. After all, I was just starting out as a relatively unknown indie author with a passion to share my knowledge of 15 years in this niche field, something which other PCB-RE engineers might not want to do or thought it too big an undertaking to worth their time or effort.

To be honest, The Art of PCB Reverse Engineering was published without any fanfare or advertising, and with much trepidation. Thankfully, the response was encouraging with readers who posted their comments on Amazon, one by a J. Ryan I thought was pretty cool:
Reverse engineering PCB's is to electronic circuit boards what hacking is to computer software... something people do, but no one admits to doing it, LOL. 
Mr Ng not only does it, but he lays out a very clear and systematic approach to the entire process. I am self-taught in this field, and it was a real joy to find that someone had actually written an entire book on the subject. I highly recommend this book to anyone interested in the topic.
Even now as I look back, the emotions still run high to know that there are those who do appreciate my hard work, though admittedly I made an early blunder as an inexperienced author to have my book published in full-colors, and consequently priced beyond the reach of the average reader due to high printing cost. I realized it soon enough and went to work to produce a non-color edition that seen a wider readership.

I was quite content to leave things as is and went to write some other genre of books, co-authored with my wife as a way of saying thanks to her for supporting me in pursuing my lifelong writing passion. But as fate would have it otherwise...
