What’s Happening at IPC’s Fall Standards Development Committee Meetings

10/15/13 – 5-32e Conductive Anodic Filament (CAF) Task Group Tony Senese, Panasonic, made an important point regarding the influence moisture has in accelerated testing for conductive anodic filament (CAF) growth in printed boards.  The frequency of field failures related to CAF growth has grown exponentially over the last decade.  IPC Task Group 5-32e has taken […]

Little Particles Yield Big Advances

The nanomaterials revolution is continuing to evolve, with little steps that will eventually combine to create major changes. In printed boards, new materials are providing improvements that make it easier to produce reliable boards at lower costs. At IPC Midwest last fall, keynoter Alan Rae of the NanoMaterials Innovation Center, said disruptive technologies were moving […]

Acronyms, Puns and Ion-free Circuit Boards

Tin whiskers are one of the headaches of the soldering world. In a word, they stink. At least, that’s one takeaway I got from Graham Naisbitt’s presentation during IPC/SMTA High-Reliability Cleaning and Conformal Coating Conference. Naisbitt didn’t really say tin whiskers stink —  rather he explained that many people try to reduce the likelihood of tin whiskers […]

Some solutions for intermittent problems

Intermittent field problems are among the most expensive warranty issues to handle. It can take years to find the root cause, then figuring out a solution to eliminate the problem can be difficult. So it’s pretty wise to take steps to avoid problems that cause sporadic failures. One of these, tin whiskers, has been vexing […]

One stop research shop on tin whiskers

Tin whiskers is a concern throughout the industry. Rockwell Collins’ Dave Hillman and Doug Pauls, two of IPC’s standards committee chairmen, put together WP-009, a white paper reference and analysis of 12 papers from industry and defense agencies on tin whiskers. Their conclusions: 1. The electronics industry considers conformal coating as an industry Best Practice tin […]
