An internal debate presently rages internally, so I thought I would turn to cool rational people (sit down Dewey). When inspecting conformal coating, one of the things that "may" be considered a defect is the presence of Foreign Objects and Debris (FOD), which "might" require disposition. 1. Is there any guidelines you all use to differentiate FOD in coating that requires action (e.g. FOD as a defect), vs. FOD that does not (cosmetic only)? 2. If you differentiate bad FOD from doesn't-matter FOD, what criteria do you use? In essence, how much FOD is FOD. Thanks.
