During placement and before soldering, the package must be xed with a droplet of
adhesive. The adhesive can be applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the adhesive is cured.
Typical dwell time is 4 seconds at 250
°C. A mildly-activated ux will eliminate the
need for removal of corrosive residues in most applications.
14.2.3
Manual soldering
Fix the component by rst soldering two diagonally-opposite end leads. Use a low
voltage (24 V or less) soldering iron applied to the at part of the lead. Contact time
must be limited to 10 seconds at up to 300
°C.
When using a dedicated tool, all other leads can be soldered in one operation within
2 to 5 seconds between 270 and 320
°C.
14.3 Through-hole mount packages
14.3.1
Soldering by dipping or by solder wave
The maximum permissible temperature of the solder is 260
°C; solder at this
temperature must not be in contact with the joints for more than 5 seconds. The total
contact time of successive solder waves must not exceed 5 seconds.
The device may be mounted up to the seating plane, but the temperature of the
plastic body must not exceed the specied maximum storage temperature (Tstg(max)).
If the printed-circuit board has been pre-heated, forced cooling may be necessary
immediately after soldering to keep the temperature within the permissible limit.
14.3.2
Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the
seating plane or not more than 2 mm above it. If the temperature of the soldering iron
bit is less than 300
°C it may remain in contact for up to 10 seconds. If the bit
temperature is between 300 and 400
°C, contact may be up to 5 seconds.
