IEST-STD-CC1246D: Product Cleanliness Levels and Contamination Control Program

The term PAC was selected over the previously used term obscuration because it was defined as the sum of the projected areas of the particles, whereas obscuration can be optical attenuation that is not directly related to area coverage. Levels were defined for both particulate and sts residue NVR molecular contaminants. Definition of document types Although the official definitions differentiate between several types of documents, all of these documents go by the general rubric of “military standard”, including defense specifications, handbooks, ieet standards.

Defense standards are also used by other non-defense government organizations, technical organizations, and industry. Total fab equipment spending reverses course, growth outlook revised downward.

Foundry-qualified and foundry-maintained reliability rule decks enable design and IP companies alike to establish baseline robustness and reliability criteria without committing extensive time and resources to the creation and support of proprietary verification solutions. Cooper 3 compared three different ways to describe particle distributions. Visibly clean inspection methods have been shown to be quantifiable in many applications when using trained personnel.

Please click here to accept. For many, formal reliability verification is a new process. Levels were defined for both particulate and nonvolatile residue NVR molecular contaminants. For the standard, the lognormal, cumulative distribution was selected and approximated by a log-log 2 equation as follows: Global demand growth for flat panel display expected to ease through Larger particles tend to be more easily removed than smaller particles, resulting in larger numbers of small particles remaining in or on the product.
