This means that if a dimension needs to be adjusted to ensure the critical dimension of the boom length is correct, it is possible to modify one or two of the 15 sections even if the sections …
WebWhen parts come in from vendors our ISO procedures require inspection of a certain number of parts based on the lot size. Our inspector normally checks every dimension on the drawing that is not marked "reference". Obviously some of the dimensions are not critical (if I can even use that term) to the part's fit and function. WebThis technique is particularly useful when applied at the after-develop inspection (ADI) step, as it allows manufacturers to rework their process without scrapping wafers. It is also expected that OCD technology will become an indispensible metrology technique in advanced technology nodes below 40 nm, where double-patterning and/or immersion ...
