MANUFACTURING INFORMATION
Parameter
Description
Solderability
MIL-STD-202, method 208, category 3
Reflow
Solder reflow processes as per attached profile. When soldering, ensure solder does not short
top and bottom castellations
Materials
Part will not contain components with 'pure tin' terminations- part is assembled with lead-
bearing solder. Termination finish: Au (0.5 to 1.27μm) over Ni (1.27 to 8.89μm) over tungsten
on an alumina substrate
