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.

Charity vs Piracy

It is a sad fact that book piracy is rampant and unstoppable in this internet age. Illegal downloading of books might not cost the person downloading them or the scumbag who stole the content in the first place, but it costs the one person who should really be rewarded for his or her months of hard work, the author.

Increasingly, though, it seems that those who are looking for free copies of pirated books are falling victims to phishing scam sites that ask gullible users to hand over their credit card information before proceeding to download their ostensibly free copies. It begs the question: is it worth the risk and trouble just to 'steal' a meager amount from a hardworking full-time author who spent so much time and effort to produce a book?

Granted, there are authors who made millions from their best-selling titles; but these are the rare breed amongst the sea of writers, many of whom are driven by a desire to share their valuable knowledge and invaluable experience through printed materials or electronic mediums. Surely they deserved to be treated with respect and dignity, not plundered and deprived of their means to keep them writing.

For me, being an indie author, I have stated before that a percentage of my book's earnings (which is not really much since I'm a non-US resident or citizen, I'm subject to a further 30% withholding tax) goes to charity. Before the Covid-19 pandemic, I was able to contribute to two organizations, namely the cancer society and the kidney foundation; but the present crisis has hit the world economy really hard and book authors are not spared either. After some deliberation, I had to cut down to just supporting one.

I'm not sure if there are readers out there who manage to get an illegal copy of my book(s). If you do, I do not intend to pursue the matter. All I ask is that you buy a meal for the poor or homeless around your neighborhood and that will be enough. A kind heart is what makes us all human, and what goes around... comes around. You never know when you'll need a helping hand.

Take care and stay safe, my friends.

Ps: For those who own illegal copies of my book, I would appreciate that you do not proliferate the piracy further by sharing with others or putting them online for free download, else you will be no different from the scumbags who do it for ill-gotten gains at the expense of others. Thank you.
