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.
