RECOMMENDED SOLDERING CONDITION
REFLOW SOLDERING
HAND SOLDERING
REMINDERS FOR USING THESE PRODUCTS
Before soldering, be sure to preheat components. The T pre-
heating temperature must be 150°C max. with attention paid to
thermal shock.
Natural cooling of components in the air is recommended. On
the other hand, when dipping them in a solvent for purposes,
such as cleaning, make sure that the temperature difference
(T) is 100°C.
When performing hand soldering for circuit modification, apply
the soldering iron to the copper foil area of the printed circuit
board for 3 seconds or less. The temperature of the iron tip
should not exceed 300°C.
Use a wrist band to discharge static electricity in your body
through the grounding wire.
When incorporating the printed circuit board on which this prod-
uct is mounted into a frame, etc., do not apply stress to the prod-
uct through local bending of the board by tightening of screws,
etc.
