7.3 Static electricity

Good caution must be exercised against static electricity since this device

consists of a bipolar IC. Following are some examples of preventive measures

against excessive voltages such as caused by static electricity.

(al frytibody

.

must be grounded to discharge the static electricity from the body

(b) Anything that is in contact with the device such as workbench,

inserter, or measuring instrument must be grounded.

(cl Use a solder dip basin with a minimum leak current (isolation

resistance 10MQ or more] from the commercial power supply.

Also the solder dip basin must be grounded.

7.4 Soldering

(1) Reflow soldering

It is recommended that within two times soldering be done at the temperature

and the time within the temperature profile as shown in the figure.

(The temperature shown in the figure is fin portion temperature of the device.)

It is recommended that the second reflow become at the device which is the

room temperature.

(a) An infrared lamp used to heat up for soldering may cause a

localized temperature rise in the resin. The temperature of

resin portion should be with in the temperature proffle below.

(bl The temperature sloping when soldering-reflow is 4E/s or less.
