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.

PCB Diagnostics

While my fourth and final book on PCB-RE is awaiting Joe Grand's Foreword, I have decided to write on a new topic: PCB Diagnostics. Why 'diagnostics' instead of 'troubleshooting', 'fault-finding' or 'repair'? Well, this word encompasses a much broader sense than the usual, and more accurately conveys what my thirty years of experience entails. Here is the front cover design:


Like PCB-RE, PCB diagnostics is a skill that is developed and refined overtime. Nothing can replace the knowledge and know-how of troubleshooting different types of PCBs. It requires not only hands on experience but in-depth exposure to a wide variety of faults to understand the dynamics involved.

I'm still in the initial phase of organizing my thoughts and materials. Once these are sorted out, I will be able to come out with a draft outline of the chapters to define what I want to write. Hopefully it will not take too long, barring any unforeseen interruption or situation arising.

    When is this masterpiece expected to be released? :)

    The book is still in the works. There are quite a bit of materials to organize and collate, before I can put into words that flow with the outline defined. A masterpiece cannot be hurried... ;)
