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.

Your Preference Reveal Your Personality

Ever been asked which type of personality you belong to? Are you the rational (left-brain) or emotional (right-brain), the engineering or artistic type? When it comes to deciding what kind of component symbols to use in schematic diagram, it seems we're faced with the same dilemma.

Not to worry though. I'm sure you already know your preference when it comes to reading or drawing electronic circuits. But in case you're still undecided, this forthcoming book will give you a better idea of your engineering inclinations.

There is really no right or wrong, good or bad when it comes to choosing symbols, ANSI or IEEE. After all, deciphering schematics won't be fun without all the flavors and quirks out there, isn't it?

Have a good weekend and try not to lose sleep over it. (grin!)
