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.

Reader from Spain (Espanol)

"The rain in Spain falls mainly on the plains." So goes the nursery rhythm. Well, now that my books have found readers in that part of the world, I can safely say that PCB-RE has also gone ashore on the plains of Spain. Here's the review of one Spanish reader, Jose RV:
He's new to PCB-RE and posed the following question to me in his email:
In order to practice some manual RE, where can I find two layer PCBs? I have some old routers but they are 4 layer, which I think will be a bit challenging.
My reply:
Double-sided PCBs are quite rare these days. You might want to try finding them at the electronics hobby shops. Four-layer PCBs are more challenging for sure. PCB designers using four or more layers are usually driven by necessity due to the complexity of their circuit designs. 
As a beginner, avoid attempting on large pin count type PCBs as you might get discouraged easily. Learn to develop your own personal style and skill, and the right strategies for different type of boards. The Art of PCB-RE and Tools & Techniques does cover these topics.
As the proud owner of my first two books, he even sent me a photo complete with a nice bed sheet background:
