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.

Year of the Tiger

According to the Chinese zodiacs, 2022 is the year of the Tiger. As the pandemic rages on, people wonder if it will go on indefinitely, or will this king of the mountain put a stop to it and restore some normalcy to daily life once again?

Reminds me of a poem by the English poet William Blake:


We'll never know for sure what 2022 and beyond holds for all of humanity. One thing I do hope is that as we move ahead, we will have the courage and resolve of the Tiger to face whatever challenges, knowing that we're not alone in this journey.

Those who are into PCB-RE will know what it takes to overcome the odds. For those who aren't, why not consider getting a copy of my books and begin this extraordinary journey of a lifetime? I'm sure it will not only enrich your engineering experience but your overall outlook of life as well.

Stay safe and strong, my friends!
