Something to think about though... > Yeah, the brand of solder may be a factor. We tried Sea Step from Easy Braid. As this is a first try, it is useful to hear what others are using. But I am a little confused here. If the Cobarcore stuff is water-clean type, then aren't you cleaning the boards after soldering? If not, why not? But if it's not water-clean, then your experience falls into the "old" category - ie, of not cleaning the old type rosin [??] flux. - DanM -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]: PIC only [EE]: engineering [OT]: off topic [AD]: advertisements
