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 Suspense is Intense...

Just last week, a reader from down-under inquired in my Facebook page about the status of my sequel book. He saw the photo I posted on the ScanCAD Edition and thought it was already released. Well, I had to disappoint him and tell him to wait a bit longer. Still, he's optimistic and looking forward to getting a copy when it's out.

In the interim, ScanCAD's CEO Bill Loving also emailed me to find out my progress on the book. He is looking forward to getting copies for his distributors and clients from over 48 countries, with an estimated 1000 companies in their business dealings over the past 27 years. In fact, he volunteered his staff to proofread the draft copies for free. I'm glad to have the strong belief and support from someone of his status and experience for my work.

Here's a two page sample taken from a chapter contributed by him and his colleague, Jeff Rupert, an experienced engineer and now director of sales and business development of the company:


Yesterday, a friend of mine Whatsapped me regarding its launch date. I told him I'm still waiting for the review and Foreword from the Editor-in-Chief of EDN. It's as if the suspense of waiting isn't bad enough for me, the intensity of waiting becomes harder to bear with each well-meaning concerns from friends and readers...
