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.

Creating a PCB Layout (Introduction)

The first thing you need to do after the preparation work (see the aforementioned ABCDs in my previous posts), is to create a PCB layout of the board you intend to reverse engineer on. The thought of creating a PCB layout, however, may seem daunting, especially to those who do not have the experience of using a CAD program. Consider the following example from my own portfolio:


Yeah, I know what you're thinking right now. Some of you might be thinking, "Wow! Is it possible for me to draw THAT?" Others might be contemplating about giving up the idea of doing reverse engineering, "You gotta be kidding! I could never do what you did even if I try..." Hopefully there'll be some who'll respond, "I like what I'm seeing and I'm gonna give it my best shot and see what I can come up with!"

Well, it's not as complicated as the first impression you might have. The book will show you how to create these professional PCB layout diagrams using Microsoft Visio, one of the best diagramming tool out there you can find. And believe me, in the process of learning how to use this amazing piece of software, you'll be able to create virtually any kind of engineering and artistic illustration your mind can imagine. And it gets even better: Visio has a hidden gem that many casual and frequent users often missed, avoid or overlooked - Smartshapes. This too is covered in the Advanced Topics of my book, which one reader commented:

Just received my copy of your book from Amazon. Amazing! This is going to be one of the most useful books I have ever bought. Visio has always been one of my favorite tools, and I would consider myself quite an expert, but you have shown me some wonderful new tricks!
