The following message is posted at the request of the leaders of the IPC Cleaning and Coating Committee: Recently there have been several questions on actual long term field performance of conformal coatings based on several anecdotal observations. There are numerous specifications and standards that address conformal coating material performance/qualification, design and application requirements. However, very little documented correlation exists between design requirements and actual long term performance under field conditions. In addition, standard communication of design requirements related to conformal coating and what performance should reasonably be expected from a conformal coating (i.e., the myth that conformal coatings are impervious to water/water vapor, etc.) does not appear to be clearly and/or readily recognize in the industry. IPC and the Cleaning and Coating Committee are considering holding a forum/panel discussion on the above issues at the fall IPC committee meetings to be held as part of IPC/SMTA Electronics Assembly Expo in Providence, RI October 24-29. Several users and customers (FAA, etc.) have expressed interest in such a forum. The objective would be to have a short presentation from conformal coating users, FAA, material suppliers, etc., addressing the above issues and any data supporting recommendations whether or not further work should be pursed by IPC membership in this area. Here's where we need your help! We're trying to determine if there is a significant interest from IPC members and other users to support holding such a discussion in Providence. If your believe the subject is of sufficient interest and would consider attending an open panel discussion, audience question and answer session on this subject, please contact Jack Crawford a the IPC ([log in to unmask]) by 28 August to indicate your level of interest. We will use the results of this poll to determine if such a session should be organized. -------------------------------------------------------------------------- Thanks, Joe Felty Raytheon Systems Company Sensors & Electronics Systems 972-952-5318 [log in to unmask] or [log in to unmask] IPC/SMTA Electronics Assembly Expo Technical Committee Meetings, Conference, Exhibits Providence RI October 24-29 More info at http://www.ipc.org Jack Crawford, IPC Project Manager - Assembly 2215 Sanders Road, Northbrook IL 60062-6135 [log in to unmask] 847-509-9700 x 393 fax 847-509-9798 ################################################################ 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.
