MOUNTING

Due to their rectangular shapes and small tolerances, Surface Mountable Resistors are suitable for handling by

automatic placement systems.

Chip placement can be on ceramic substrates and printed-circuit boards (PCBs).

Electrical connection to the circuit is by individual soldering condition.

The end terminations guarantee a reliable contact.

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. 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.
