STORAGE
Good solderability is maintained for at least twelve months,
provided the components are stored in their “as received”
packaging at less than 40°C and 70% RH.
SOLDERABILITY / LEACHING
Terminations to be well soldered after immersion in a 60/40
tin/lead solder bath at 235 ± 5°C for 2 ± 1 seconds.
Terminations will resist leaching for at least the immersion
times and conditions recommendations shown below.
NB products are compatible with a wide range of soldering
conditions consistent with good manufacturing practice for
surface mount components. This includes Pb free reflow
processes
Recommended profiles for reflow and wave soldering are
shown below for reference.
NC products are recommended for lead soldering application
or gluing techniques.
