When you mix high purity "low drossing" solders that contain Ph with lower purity solders you will create more dross than with either of the two when used seperately. I don't see a problem when mixing two lower grades...but the mixture can be catostrophic to a wave solder machine. The nature of the organic low drossing additives pull contaminates out and to the top. I would just understand my chemistries before mixing them up.

If it were to happen, for whatever reason, each solder bar manufacturer could then point at the other. Unless you are talking a lot of solder I would recycle it or use it in a small static solder pot, not in one of your wave solder machines. regards, Bev Christian Nortel Networks > -----Original Message----- > From: West, Jim [SMTP:[log in to unmask]] > Sent: Wednesday, July 28, 1999 4:40 PM > To: [log in to unmask] > Subject: [TN] Mixing solder bars from different manufacturer's > > Hi all, > > This might be a silly question, but I received some left over solder from > a > customer that is made by a different manufacturer than what we use.
