[Dehoyos, Ramon] Heat the PCB in an oven at 190 deg F for about 4 hours minimum pull it out and place it on a material that keeps it from loosing heat such as an oven glove. Using a heat gun and a wide solder tip, heat up an area with the gun and push up the masking with the tip. Sharpen the solder tip so that is thin and sharp so that it gets under the solder mask easier. It works fairly fast. The heat gun has to be kept in motion so that heat does not build up in one spot and cause delamination Regards, Ramon --------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8e 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 or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/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 -----------------------------------------------------
