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.

Covid-19 Positive!

Ever since Singapore announced an endemic (living with Covid-19) policy with relaxed measures and opening up of borders through VTLs, the onset of Omicron has seen a marked increased in the daily cases of infection, though mostly with mild symptoms. Our health minister even preempted that it's only a matter of time before any of us will get it.

Last Friday, I woke up with body aches and a slight feverish feeling, so decided to do an Antigen Rapid Test (ART). It turned out positive. My wife did hers and the results confirmed that both of us are down with Covid-19.

According to the latest health protocol, it has to be 72 hours before we do another ART to assess if we are OK or need to serve a longer home recovery program.

Hopefully, at least one of us will be negative so we do not need to trouble our friends to help us get the groceries and meals. The so-called mild symptoms are not in anyway trivial as we experience coughs, vacillating fevers and muscle aches. I could only manage to do a bit of writing but most of the time I'm down and out due to fatigue from fighting the virus, despite having been vaccinated.

That's all for the update. Mind's a bit foggy right now...
