Given the current trends toward smart infrastructures, industrial internet of things (IIoT), and connected and electric vehicles, electronic circuit boards are deployed into humid and potentially corrosive environments arguably to a greater extent than ever before; hence, they are at greater risk of failures due to electrochemical migration (ECM).
Written by Graham Naisbitt of Gen3, this book explores how establishing acceptable electrochemical reliability can be achieved by using both CAF and SIR testing.
This is a must-read for those in the industry who are concerned about ECM and want to adopt a better and more rigorous approach to ensuring electrochemical reliability.

Graham K. Naisbitt is a Freeman of the City of London, a Liveryman of The Worshipful Company of Marketors, and the recipient of the IEC Lord Kelvin 1906 Award. Graham began his career in 1969 at Socaltra, a French industrial engineering consortium. Later, he worked with French heavy-engineering giant Fives Group, and between 1979 and 1985, he served at Claudius Peters AG, a German subsidiary of Babcock International.
In 1979, the Naisbitt family created Concoat Ltd., to which Graham returned in 1985, making the logical step change from heavy engineering into the electronics industry as the U.K. distributor of HumiSeal. From 1979 to 2005, Concoat grew to become the manufacturing licensees of HumiSeal conformal coatings whilst also creating many of its own coating formulations.
Concoat began to develop conformal coating application equipment that extended to both in-line dip and spray coating systems in 1982. By 2002, Concoat acquired Multicore Solders SPCID (Soldering Process Instrumentation Division) from Henkel KGaA, thus expanding its equipment manufacturing division. Following the sale of Concoat to HumiSeal, Gen3 was created in 2005. Both of Graham’s sons have since joined the business as the third generation of the family.
With over 40 years in the electronics industry, Graham is a specialist in conformal coating, cleaning, SIR and CAF testing, electrochemical reliability issues, solderability, and process control matters; has authored over 100 technical papers; and given presentations around the world. He is also the current vice-chair of IPC 5-30 Cleaning and Coating Committee that embraces 15 test standard groups and a maintenance leader with IEC TC91 for SIR, CAF, ionic contamination testing, and solderability. Graham is chairman and CEO of Gen3, which continues to be a successful, family-controlled business.
