SOLDERING CONDITION
The robust construction of chip resistors allows them
to be completely immersed in a solder bath of 260°C
for 10 seconds. Therefore, it is possible to mount
Surface Mount Resistors on one side of a PCB and
other discrete components on the reverse (mixed
PCBs).
Surface Mount Resistors are tested for solderability at
245°C during 3 seconds within lead-free solder bath.
The test condition for no leaching is 260°C for 30
seconds. Typical examples of soldering processes that
provide reliable joints without any damage are given in
Fig 3.
