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 Companion Book in the Works...


Readers who have recently bought Solutions to Obsolescence would no doubt have noticed the discussion questions posed at the end of every chapter. Questions are a means to help readers understand and grasp what they have read. 

This is also a departure from my usual style of writing, since remanufacturing was new to me when I started out to learn the subject through researching and writing. It has tremendously enabled me to not just know how the three R's are interrelated to solving obsolescence, but also appreciate the dynamics between them in ways I did not preceive before.

Again, besides a visual aid like the book cover above, I will need a book blurb to help me focus on my writing. I anticipate that this will be a smaller workbook than the textbook, but it will no less be as informative and practical with many full-colored illustrations. I hope to finish and publish it in 3-4 weeks' time, if schedule allow.

So stay tune for more updates...
