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.

Radar Technician

Republic of Singapore Air Force (RSAF)
September 1983 to May 1990

Initial OJT attachment to the Gombak Hill ground radar squadron, working on the RAF Type 80 EW radar and two HF200 height finders. Later a TPS-43 stacked beam radar was added by RSAF to modernize its airspace monitoring capabilities.

Six months later, was transferred to Tengah Airbase and worked on the Emerson ATE running on a PDP-11/40 that serviced the A4 Skyhawk honeycomb radar system.

Trained at the Grumman Aerospace Plant 18 facility in New York, Long Island as part of the E2C avionics bay repair and maintenance crew. Operated the CAT-IIID and RADCOM test stations running on the ATLAS IEEE-416 language under the tutorage of Ronald Paul Dykeman and Robert McLaughlin.

In turn, trained three local batches of technicians on these weapon systems before leaving the military service.
