Hi Alexis, and IPC LF Listservers,


I am going to disagree with all of our listservers who have responded to
date. This is because your question was a bit broader than changing solder
metalurgy.

YES I would requalify, without any question. I have engineered in all
phases of manufacturing and development for printed circuits and assemblies
and the changes that occur by good meaning people, engineers, suppliers can
cause great changes to the final product's performance.

ReQualify that puppy, and you will learn.

YiEngr, MA/NY DDave
