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.

A Chef's Signature Dishes

I'm a lover of gourmet food though it's only during festive seasons that I'll treat myself and my wife to a really good meal (within our means, of course!). So Chapter 6 on Signature Analysis seems like a great idea to write at this point leading up to the Christmas seasons. And I'm pleased to say that I'm making rather good progress, making up for some lost time.

Here's a two-page sample just to whet my readers' appetite (pun intended):

To those who are well-versed in this technique of PCB diagnosis, the introductory information may look elementary; but those who are new to it will appreciate and perhaps be thrilled to know about it. I will dish out more delectable signature dishes to satisfy my readers' taste buds after I've whipped up enough recipes (boy, am I feeling like a Masterchef now!).

Stay tune for more updates, and more importantly, stay safe during this festive period. Do help to spread the word and promote my works so I can bring my supportive wife to a good restaurant for her well-deserved Christmas break. Thanks!
