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 235C during 2 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.
