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.

Season's Greetings

Christmas always convey an atmosphere of peace and hope, especially in a world that is filled with so much problems and sadness. People seem more joyful during this period as they meet with family and friends to enjoy a wonderful time together, renewing bonds and friendships.

While searching for a greeting card for this post, I stumbled upon a rather interesting one that resembles an engineering drawing:


It's a Nativity scene done by the staff from Engineering Ministries International (eMi) who, since 1982, have worked on over 1,000 relief and development projects in 90+ countries. Their most recent projects involve relief work for those affected in the Mexico earthquake and the Caribbean hurricanes.

While part of the proceeds on the sales of my first book goes to two local charities in my country, I am considering apportioning a sum from the sequel book for this organisation. Readers who buy my books will indirectly be supporting a worthy cause and helping the less fortunate.

Christmas is a time of caring and giving. Let us bring some cheer and hope to those who need it, in whatever limited capacity we are able to. Have a wonderful and meaningful Christmas!
