We re-tin thousands of surface mount RoHS components everyday:-) Gary AEM, Inc. _____ From: tinwhiskers-bounce@xxxxxxxxxxxxx [mailto:tinwhiskers-bounce@xxxxxxxxxxxxx] On Behalf Of Fritz, Dennis D.

Component "lead" is too well entrenched to change. So, dare we call lead metal solder parts Pb'd or Pb'ed finish? Also, wish we had called the RoHS compliant parts "Pb safe" or "Lead-Safe" and not Lead-Free, as they can contain 0.1%, or 1000 ppm, of Pb. The utlimate oxymoron is to take a Pb-Safe component and "re-tin" it with Pb based solder. What a mess!!!!!

It would nice if we could work out a way of distinguishing between "leaded" meaning having contacts via leads rather than pads and "leaded" meaning containing the element lead. regards, Rod rod.dalitz@xxxxxxxxxxxxxxxx
