SMTnet's OnBoard Forum to Feature Gil Zweig

June 18, 2001 8:00 AM EST to June 22, 2001 5:00 PM EST

In developing it's innovative X-ray systems; Glenbrook Technologies draws on two decades of experience in the science of X-ray luminescent phosphors. Gil holds 20 patents and has published basic research papers in both medical and scientific journals.

As a member of the technical subcommittee IT2-31 of the National Association of Photographic Manufacturers (formerly the American National Standards Institute), Zweig was active in setting US standards for medical X-ray film and intensifying screens. He is also a reviewer for the technology transfer program of the New Jersey Commission on Science and Technology.

In 1994, Zweig was named an "Inventor of the Year" by the Inventor's Congress and Hall of Fame at the New Jersey Institute of Technology, for the patented X-ray camera technology he developed for Glenbrook's inspection systems.

Topic Summary

Real-Time X-Ray Inspection has become a critical production and laboratory tool when analyzing the integrity of solder bonds of various type components assembled on Printed Circuit Boards (PCBs).

While the most prevalent component type today are BGAs, X-ray inspection is also proving to be useful for a variety of other advanced packages like Flip Chip and CSP. Interpretation of these images or "signatures" can be a complex process, when they are correlated to process control issues.

Glenbrook, has been in the X-ray Inspection business exclusively for over 18 years, and has pioneered the use of X-ray inspection in electronic fabrication.

Solder Paste Measurement: A Yield Improvement Strategy That Helps Improve Profits
by Mike Riddle , ASC International, INC.

In this age of global competition, world class electronics manufacturers understand that increasing profit margins is accomplished not by increasing price or lowering the quality of components and workmanship, but by increasing production yields.

A yield (and profit) improvement strategy consists of...

Engineer-to-Engineer Communications
by Bill Gotha , Ward Hill Marketing, Inc.

Talk about a rock and a hard place. There are few environments that are as challenging as facilitating communications between an engineer and an engineering audience. It's not like an end-user environment, where color, smell, and personal goals come into play. It's further still from retail (cosmetics copywriters beware). For marketers of technology, the challenge is a daily one, whether...
