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.
