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.

Happy 57th National Day!

This year 2022, our little island nation celebrates its 57th independence year with the usual and much anticipated National Day Parade (NDP) at the Marina Bay Floating Platform.

The theme for this year is 'Stronger Together' and celebrates Singapore and Singaporeans going through the two-year pandemic and emerging stronger together as a people. For readers who have not visited our country or seen the parade, you can watch a past year sample video to get a feel of it (click on the image below):

You can expect whole-hearted participation from people of all walks of life, the military with its smart uniforms and contingents, the guard-of-honor that does the 'feu de joie' (3 shots of firing of joy), the 21-gun salute as the president inspects the guards, fly past of fighter jets and Singapore flag, large-scale formation dances that depict the theme, dashing celebrities rendering the newly composed national day song and those favorites of yesteryears, and not forgetting the spectacular fireworks at the end of this two-hour plus grand event.

It is a time to be thankful for the many blessings we share among families and friends, and for the nation our forefathers had built up so that generations that follow can enjoy the fruits of their labor. And many foreigners who have chosen this island-country to call it their home can vouch for the wonderful opportunities presented to them to live and work as one of its privileged citizens.

Cheers to Singapore's 57th birthday, with many more years to come!
