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.

Setbacks and Crawlbacks

If being a self-publish author is hard enough, imagine trying to orchestrate several contributors for an engineering book!

In the second half of last year, I invited five PCB-RE engineers to contribute a chapter each for my trilogy book. Along the way, one dropped off after showing initial enthusiasm; then another delayed replying my emails and I found out later that his dad passed away and he was having a hard time coping with work. Then near Christmas, the one whom I had such high hope dropped a bomber and pulled out after telling me he's just landed on a new job.

Such frustrations and disappointments are real and can sometimes throw the progress of a book off course or even terminate it prematurely. But I'm not one to give up easily, so in the midst of these setbacks, I have worked doubly hard and come up with two additional chapters to compensate for the loss. The chapter on X-Ray PCB-RE using an Arduino UNO is near completion. Here's a two-page sample:


I foresee the release of the trilogy book will be delayed till early February or perhaps March. Readers of my first two books will have to wait a bit longer, but I'm sure it will be worth the while...
