Honeywell’s Low Alpha Technology Leadership
Honeywell is the leader in alpha flux measurement and the development of Pb-free low alpha products.
In 2004, Honeywell led the industry in proposing standards for alpha flux measurement. These standards established a basis for comparison across industry participants rooted in best scientific practices and were adopted by JEDEC in 2011.
Our experience in manufacturing low alpha materials spans more than two decades. During this time, we’ve successfully developed proprietary refining techniques and significantly advanced our capabilities in metrology.
Our proprietary refining technique selectively removes alpha-emitting isotopes. This enables our materials to reliably meet ultra-low alpha grade (less than 0.002 counts/hour/cm2) and satisfy the critical alpha emission levels required of advanced flip-chip packages.
Honeywell employs state-of-the-art metrology across our supply chain to ensure precise measurement of alpha emissions. At extremely low alpha emission levels, measurement of alpha flux is difficult due to the effects of contaminants and background radiation (see chart below). Robust processes controls are required to accurately distinguish material emissions from background emissions.
