We typically use a thickened Urelane coating as a bonding agent around connectors to prevent this, the products we use are Urelane 5753A/B with 5753TX added as a thickener. This has worked very well for us, we spray with either Urelane 5750 or Humiseal 1B31, the bonding works with both. We also use this to bond parts or jumper wires to boards with good success. --------------------------------------------------------------------------------- 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 ---------------------------------------------------------------------------------
