Hi Graham! A standard industry point of reference is that any process that
joins two metals with a filler metal without melting and is below 800 F is
termed soldering. A process that joins two metals with a filler metal
without melting and is above 800 F is termed brazing. There are processes
such as joining two aluminum sheets together with a filler metal (without
melting the two Al sheets) at temperatures around 1100 F. Unless the
flexprint is really thermally tough I imagine the customer meant a
soldering process instead of a brazing process. Have fun.

Subject: [TN] brazed connector on flexprint
Hi TechNet
Today's question: A friend outside my company has a RFQ for a job that
calls for connector pins brazed to a flexprint. He's not sure what this
means. Is this requirement unusual, and is it different from soldering the
pins to the flexprint? I know that brazing is joining two metal surfaces
with a third, different metal, which could include soldering, but I'm
wondering if something else is meant by this.
regards,
