SOLDERING CONDITIONS
REMARK
—
Solder no closer than 2mm from
DIP
SOLDERING
Bath temperature: 260 max
Immersion time: within 5 sec
the base of the package
—
Using soldering flux,” RESIN FLUX”
is recommended.
—
During soldering, take care not to
Soldering iron: 30W or smaller
press the tip of iron against the
SOLDERING
Temperature at tip of iron: 260
℃
or lower PIN.
IRON
Soldering time: within 5 sec.
(To prevent heat from being
transferred directly to the PIN.)
1) When soldering the PIN of Display in a jig that the package is fixed with a panel (See fIg.1), be
careful not to stress the PIN with iron tip. When soldering Display in a condition that the package is
fixed with a panel, be careful not to cling and stress the surface of Display on the panel to avoid
damaging the Display.
Fig.1
Regarding solution in the tinning oven for product-tinning, compound sub-solution made of tin &
copper and silver is proposed with the temperature of Celsius 260. The proportion of the
alloyed solution is tin 95.5: copper 3.5: silver 0.5 by percentage. The time of tinning is constantly
3 seconds.
