This has long been standard practice for military hardware and is specifically detailed in both MIL-HDBK-263B par. 5.10 (Packaging) and within MIL-STD-1686. It is also listed as standard handling procedure in MIL-STD-2073. The handbook specifically states "Normally contracts and delivery or purchase orders specify exact packaging requirements using MIL-STD-2073 packaging requirement codes (PRCs). When packaging requirements are not otherwise specified, ESD protective packaging shall be as specified in MIL-E-17555 in accordance with MIL-STD-1686. MIL-STD-1686 contains the additional requirement that ESD protective caps shall be used on equipment (with) external connectors connected to ESDS parts and assemblies within the equipment. The MIL-STD-1686 requirement for protective caps complements and is in consonance with MIL-STD-454, requirement 10 for the protection of unmated connectors with metal or plastic caps during maintenance, storage, and shipment." There you have it. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Graham Collins Sent: Monday, December 04, 2006 9:12 AM To: [log in to unmask] Subject: [TN] ESD caps for external module connectors Hi TechNet An ESD question. Our standard practice is that all electronic modules have ESD safe connector caps installed on the external connectors of the module, to protect the unit in transit. The logic being that the connector connects to the CCA within, and so it has to be protected... We have a customer questioning this - asking "why do I have to pay for this if I don't tell you to do it". A quick review of the applicable documents hasn't turned up a formal requirement to do this, but maybe one of the TechNet experts can point me in the right direction. Is this a formal requirement, and if so where? Note, this is on military product, IPC class 3. Thanks! regards, Graham Collins Process Engineer, L-3 Communications Electronic Systems Inc.
