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.

The Published Author


It's been over ten years since I exchanged the workbench for the writing desk.

Ten years. A decade. When I look back, it feels both long and short—long in terms of what I've accomplished, short in terms of how quickly the time has passed.

I have written a total of six engineering books. Each one well received by the engineering community. Each one contributing, in its own way, to the body of knowledge around PCB reverse engineering.

But I didn't stop there.

In between the engineering titles, I ventured into other genres. Family. Faith. Fiction. Writing, like engineering, is multi-disciplined. I couldn't be content with just writing about technical stuff. There were other stories to tell, other worlds to explore.

You never know what you're capable of until you try. That mantra has stuck with me through all these years.

In the process, my writing journey took on a life of its own. Not by compulsion or necessity, but by the sheer pleasure of discovering new worlds. Of seeing what words and imagination can come up with when you give them free rein.

Through trials and errors, I've come to realize that not every genre works for every author. My non-engineering books are well-received by peers and friends. That's about it. 

I've wished, sometimes, that international readers would give my other works a chance to land on their bookshelves—the way they did the engineering titles.

But perhaps that's not how it's meant to be. Perhaps my engineering voice is the one that resonates beyond my immediate circle. 

And that's enough. More than enough.
