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.

Reader from Pakistan

Yesterday I received an email from a reader who resides in Pakistan, requesting for the free resources on the purchase of my books. Here's what he wrote:
I have had the chance to read your books and I did really enjoy it. It contains good references for beginners to understand the concept and build on the foundation. The experiences you shared for PCB troubleshooting is another area on which you can write a complete book, I think. I would definitely love to learn from your experience. A step by step guide based on your experience can help a lot to others trying to understand/learn the work. 
The thought of writing about PCB repair and troubleshooting did cross my mind, but given the current schedules I have there is no way I can squeeze out more time for that. Of course, this is not a niche subject to write on, judging by the available books and resources online. Given a choice, I would rather write on PCB testing on different ATE platforms, something which I had mused on in previous posts.

Readers who have hands on experience in any of these automatic test equipment (ATE) are welcome to leave your comments here. If the response is good enough, I may consider writing about them...
