Phil, The simplest method is to dip the wire in a solder pot (~500°F, 260°C). This removes the coating and tins the wire at the same time. Most polyurethanes and nylon coatings are in thermal classes of 105°C, 130°C, 155°C and 180°C which should be removable while immersed in molten solder. The dwell time will be significantly longer than what is used to tin temperature sensitive components. Another method is thermal strippers. The least favorite and hardest to control is abrasion using an exacto knife. Steve Sauer Manufacturing Engineer Northrop Grumman, Xetron -----Original Message----- Anyone have a reliable safe method of removing the polyurethane and nylon coating that protects magnet wire so that the wire can be used to solder as a jumper wire. I remember using a hot chemical salt type stripping bath many years ago but was hoping that someone has found a better way to do this since then. --------------------------------------------------------------------------------- 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 e-mail to [log in to unmask]: SET Technet NOMAIL To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest 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 ---------------------------------------------------------------------------------
