Good morning everyone, I had a couple of questions concerning the prevention of fretting corrosion. I am in the process of reviewing and updating some of our older process procedures. At present the procedure on Lubrication of Connectors is setting in front of me and I have managed to raise a few questions. A search of the Technet archives and some old memory banks have produced: gold to gold - its a good thing, no lubricant required: tin/lead to tin/lead - its a good thing if lubricated: gold to tin/lead - not good, even with lubrication. I know some of the information on this subject is dated, but I don't believe the passing of time has invalidated it. On products where we build the entire assembly, I can easily verify the total connector configuration. However, when we are building only a circuit board assembly for a customer, I have no idea of materials used in the mating connectors. To further complicate the issue, I know that some connector manufacturers lubricate the tin or tin/lead female connectors and some manufacturers do not, or at least won't verify that they do. Is there an industrial specification/requirement for the lubrication of connectors on circuit board assemblies that should be called out in the product specification? At present we are using a contact lubricant on all tin or tin/lead plated male connector contacts, except when the mating connector is known to be prelubricated. The lubricant we are using must be allowed to cure out 24 hours prior to assembly. This is not real conducive to lowering cycle times. Is anyone aware of a contact lubricate the would improve on this? Thanks, Gary Camac
