Hi doug, We have eliminated this problem by going to a urethane based bonding agent for component bonding. We use Urelane 5753A/B thickened with 5753TX (Furane products). We try very hard not to get any silicone containing products on our boards to prevent dewetting, and the other such problems that come along with their use. We have found that this bonding material is compatable with the two coatings we use, Urelane5753, and Humiseal 1B31, and performes well over the temperature range you specified. --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
