People I am looking for some assistance in justifying the non-use of silicone grease, ie Dow Corning 304, near soldered joints. Could someone please supply me with a route to suitable documentation/reports to support this? I understand that if silicone grease should get on a joint prior to soldering, there is a very good chance thatthe soldering process will be faulty. I am not so clear as to long term effects of silicone grease maybe migrating into soldered joints causing degredation and failure in service. The manufacturing site I am currently working with are unhappy about having silicone grease in their factory so I am having to find suitable alternatives. The difficulty is that my engineers are more than happy with silicone, but do not have to worry about long term effects. Your help would be appreciated. Regards Dave Thomas Nothing will ever be attempted, if all possible objections must first be overcome. -- Samuel Johnson, "Rasselas", 1759 =============================================================== Dave Thomas Nortel plc Principal NPI Engineer, London Road European Radio Harlow Essex Telephone: +44 1279 402901 CM17 9NA Facsimile: +44 1279 402100 UK ESN: 742-2901 E-mail: [log in to unmask] =============================================================== ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
