METHOD SOLDERING
CONDITIONS
REMARK
DIP
SOLDERING
Bath temperature: 2605
Immersion time: with 5 sec
Solder no closer than 3mm from the
base of the package
Using soldering flux," RESIN FLUX"
is recommended.
SOLDERING
IRON
Soldering iron: 30W or smaller
Temperature at tip of iron: 260 or lower
Soldering time: within 5 sec.
During soldering, take care not to
press the tip of iron against the
lead.
(To prevent heat from being
transferred directly to the lead, hold
the lead with a pair of tweezers
while soldering
1) When soldering the lead of LED in a condition that the package is fixed with a panel (See Fig.1),
be careful not to stress the leads with iron tip.
2) When soldering wire to the lead, work with a Fig (See Fig.2) to avoid stressing the package.
