Moisture-sensitive Components - TOTECH GLOBAL
www.totech.comMoisture-sensitive Components Robert Rowland The topic of moisture-sensitive components is rather boring but very important — and frequently misunderstood. Increased moisture-sensitive component use, such as thin fine-pitch devices and ball grid arrays (BGA), has increased concern for this failure mechanism. When components are exposed to the

MOLD & MOISTURE PROBLEMS THE PUBLIC HEALTH ISSUE
www.dhhs.nh.govAll mold problems are a moisture problem. If you see mold or if there is an earthy or musty smell, you should assume a mold problem exists. Look for signs of excess moisture or water damage. There are three major sources of unwanted moisture in the home: weather leaks from outdoors, plumbing leaks, and condensation from indoor air.
