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.
