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.

2018

2017 has been a momentous year in terms of political, social, economical and environmental bearings for many people. The increasing antagonism and distrust between nations, the racism and intolerance that led to ethnic genocides and displacement, resulting in a complex refugee problem that even the UN is helpless to resolve; the loss of jobs and stability for the average person due to automation, outdated business models or obsolete skillsets, further widened the disparity gap between income groups that impact social cohesiveness; last but not least, the erratic weather conditions that brought heavy rainfalls in some regions and severe drought in other parts of the world, and the destructive forces of nature (hurricanes, earthquakes, raging fires, torrential floods, etc.), cast a dark and long shadow over the ending year.

So what can we look forward to in the coming new year? Is there any glimmer of hope for a better and brighter tomorrow? Nobody can be certain about it. But life still goes on and so must we, one day at a time. Perhaps as we bask and revel in the jovial mood of transition into a new year, it'll be good to pause for a moment and ask ourselves how we can make a difference in the community we live and work in. If each one of us can do our bit to bring a smile to those around us, the world may become a better place.

Here's wishing all my readers a wonderful 2018. Stay healthy and happy!
