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.

Distraction, Diversion...

In the midst of this worldwide pandemic, where social restrictions can put a toll on everyday life, people are getting stressed up handling work and family pressures at the same time, while working from home. As an author, I too feel the same sentiments and that can lead to writer's block that stamps out inspiration to write on a particular topic. I desperately needed a distraction or some kind of diversion.

Being the artistic type, I figured it would be good to immerse in a little design activity instead of just typing all day long on the keyboard, when my brain could not produce any meaningful narrative at the moment. So after the first attempt followed by a few refinements later, here it is:


I like drawing and designing a lot, which is why Visio is a life-saver and a delight to use. Of course, designing book covers is also one of the favorite part in my present writing endeavor. Hopefully, this book will materialize one day...
