Hi, Is anyone out there having problems with solder balls and splashes in your hand soldering process using no clean solder/flux? We've been using Kester SN63PB37 alloy solder, QQ-S-571-F-WLRP-1, and 961 flux, in our application and found that it produces solder splashes and solder balls. Is there a way of preventing this condition? ############################################################## TechNet Mail List 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 web site (http://www.ipc.org/html/forum.htm) for additional information.
