Good afternoon techies, I'm hoping someone here can give me some insight into Mil-std-129 & Mil-std-130. I have some very small parts (approx. 280 pcs., on an 18" X 24" panel, parts are approx. .400" X .300"). The parts are type 2, all Kapton/acrylic construction, with laser skived covercoat openings, and absolutely no plating. The parts are too small to mark, and the customer print states: "this item cannot be physically marked or tagged, unit container shall be marked in accordance with mil-std-129 as directed by mil-std-130". That's it. I understand that the unit container must identify the following: Cage Code Customer Part No. & Revision Date Code The part I am a little foggy on is the piece/part traceability, and parts per unit container. If this were one of our typical rigid/flex boards, I would identify each part with a unique lot traceability number which could be used trace each individual part back to the panel from which it came (as required by 130). But in this case, there is no plating. Do I still need to uniquely identify each individual part/panel, or can I group parts from the same panel into one bag? For that matter, can I group all parts from a production lot into one bag, avoiding the need to identify down to the panel level? While where at it, is there a limitation to how many parts can be placed in the "unit container"? Any assistance would be greatly appreciated. If you know of relevant sections within the specs (129 & 130), please reference them. There's about 147 pages of awfully dry reading ahead, unless someone can give me some guidance. Thanks in advance.
