Not smelly. "All professional skills are mastered by critiqued practice" - by Schon. Original Message From: Greg Munie Sent: Wednesday, April 9, 2014 12:50 PM To: [log in to unmask] Reply To: TechNet E-Mail Forum Subject: [TN] Definition of Sulfur Free Anyone have a working definition of "sulfur free" as it impacts solderability of silver finishes? As an old chemist I would expect the definition "sulfur free" could have both a concentration and a time a part can be exposed to that concentration before soldering is impacted. Any thoughts/assistance is appreciated.
