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.

안녕하세요

If you're wondering, the post title means "Hello!" in the Korean language. After posting my findings on a Korean PCB-RE engineer and reader's blog sometime in early May, I finally received a comment - in fact, two - the same one in each of the two posts:


I am impressed with his level of English expression, considering that many Koreans are not very apt with this international language. Believe me, I've been to South Korea in 2012; it's challenging to converse with the locals there if you do not have a modest amount of Korean vocabulary. That said, I'm sure many are seeing the importance of picking up English, especially after the recent de-nuclearization summit between Trump and Kim Jong Un in Singapore early June this year.

My third book (trilogy) is still in the works though, and I got the nagging feeling it will take much longer than the sequel to complete. Given the technical nature of such a niche topic, I'm not sure how well it will go with non-English speaking readers. Perhaps this Korean gentleman might consider translating my books for the benefit of his own people, since he has the desire to propagate the PCB-RE technology in his country.

Just a thought for now but who knows, it may become a reality (if he reads this post)...
