SOLDERING CONDITIONS

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
