We are running humidity tests (to prove out cleanliness) on some of our assembled PWB's according to MIL-STD-810E methode 507.3 procedure 1. (this is 10 cycles of 24 Hr; temperature between 88F (31C)- 105F (41C) humidity between 88 aan 59 %) Does anyone have data on the aging effect of this test on the product? thanks! ################################################################ 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 web site (http://jefry.ipc.org/forum.htm) for additional information.
