Full Description

1.1 This method covers the size distribution analysis of particulate contamination, 5 m or greater in size, either on, or washed from, the surface of small electron-device components. A maximum variation of two to one (33 % of the average of two runs) should be expected for replicate counts on the same sample.

Note 1--For satisfactory results on clean parts, it is recommended that all procedures involved in sample preparation be conducted under a dust shield.
