TeleLink Fuse Soldering
TeleLink Fuse Soldering
For wave soldering a TeleLink fuse, the following temperature and time are recommended:
•
•
Reservoir temperature of 260 °C (500 °F)
Time in reservoir — three seconds maximum
For infrared, the following temperature and time are recommended:
•
•
Temperature of 240 °C (464 °F)
Time — 30 seconds maximum
Hand soldering is not recommended for this fuse because excessive heat can affect the
fuse performance. Hand soldering should be used only for rework and low volume samples.
Note the following recommendations for hand soldering:
•
•
Maximum tip temperature of 240 °C (464 °F)
Minimize the soldering time at temperature to achieve the solder joint. Measure the fuse
resistance before and after soldering. Any fuse that shifts more than ±3% should be
replaced. An increase in resistance above this amount increases the possibility of a
surge failure, and a decrease in resistance may cause low overloads to exceed the
maximum opening times.
•
Inspect the solder joint to ensure an adequate solder fillet has been produced without
any cracks or visible defects.
