Process 5
1. Upon completion of automatic soldering, use a
Cooling
fan or other device to forcibly cool the PCB. This
helps prevent the Relay and other components
from deteriorating from the residual heat of
soldering.
2. Fully sealed Relays are washable. Do not,
however, put fully sealed Relays in a cold cleaning
solvent immediately after soldering or the seals
may be damaged.
Process 6
Refer to the following table to select the cleaning
Cleaning
method and solvent.
Cleaning Method
Neither boiling cleaning nor immersion cleaning is
possible.
Clean only the back of the PCB with a brush.
Process 7
1. With the G7S or G7SA, coating will penetrate
Coating
inside Relays and damage the contacts.
Therefore either do not apply coating at all or
apply the coating first, before mounting the
Relays.
2. Be very careful in selecting the coating material.
Depending on the type of coating selected, it may
damage the Relay case and chemically dissolve
the seals, causing them to lose their sealing
capability.
