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.

A Special Birthday Request

Two days ago, I celebrated my wife's birthday. She did not ask for anything fanciful or expensive, just something simple: kite flying. So I bought her a beautiful butterfly kite that could be easily self-assembled and we went to a nearby coastal park after breakfast to fly it. Thankfully the weather was sunny with a cool breeze, which made kite flying a breeze (pun intended).

See how happy and delighted she was? That's the simple pleasure of life!

As it was a weekday, there were not many people around so we literally had the whole field to ourselves, which was kinda nice. Since the kite was on 'auto-pilot' we decided to sit near the shoreline and listen to the waves splashing while enjoying some quiet moments together. A few passers-by seemed absorbed with the quiet fun we're having, and one even requested to take a snapshot for us. For lunch, I treated her to a vegan Thunder Tea rice.

It's my way of showing appreciation and saying thanks to her for being supportive of my writing journey the past six years, this year being the seventh and probably the last. Thanks, my love, for being there and encouraging me to fulfil my dream and passion as an author!
