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.

ROMCOM or RADCOM?

I'm more of an intellectual guy but my wife thinks I'm the romantic sort, especially when it comes to special occasions like her birthday and our anniversary, or when my mood dictates it. Maybe that's why I started out being trained on the RADCOM test station in my air force days; it turns out a change of just a letter or two does make a huge difference!

The good news is, I managed to complete Chapter 7 on Automated Test Equipment, though it took two extra days because I had to come out with some additional illustrations. Here's a two-page sample for my readers:

Since I have yet to hear from my engineer friend (probably he's on long Christmas holiday), I guess I'll have to start with Chapter 8, the topic on Thermal Imaging. Hope I can finish it by year end, if not another week would be just fine. By then, hopefully I'll hear from that friend so I can work on Chapter 6.

Will there be a Chapter 9? Well, I still haven't make up my mind yet. There's also the Appendices that needed some work as well. By the look of things, PCB Diagnostics will probably come out some time in February next year. Maybe it'll be on time for release on our anniversary. Now, what would my wife have to say about that?

O darling, you're such a RADCOM guy!

Well, I certainly hope not...

Ps: ROMCOM - romantic comedy
