Mounting SSR to PCB
Read the precautions for each model and fully familiarize yourself
with the following information when mounting the SSR to the PCB.
Step 1
1. Do not bend the terminals to make the
SSR mounting
SSR self-standing, otherwise the full
performance of the SSR may not be
possible.
2. Process the PCB properly according to
the mounting dimensions.
Step 5
Cooling
1. After soldering the SSR, be sure to cool down
the SSR so that the soldering heat will not
deteriorate the SSR or any other components.
2. Do not dip the SSR into cold liquid, such as a
detergent, immediately after soldering the
SSR.
Step 2
Flux coating
Flux
1. The flux must be a non-corrosive rosin
flux, which is suitable to the material of
the SSR.
Apply alcohol solvent to dissolve the flux.
2. Make sure that all parts of the SSR other
than the terminals are free of the flux. The
insulation resistance of the SSR may be
degraded if there is flux on the bottom of
the SSR.
Step 6
Cleaning
Step 3
Preheating
1. Be sure to preheat the SSR to allow better
soldering.
2. Preheat the SSR under the following
conditions.
Temperature 100°C max.
Time
1 min max.
3. Do not use the SSR if it is left at high
temperature over a long time. This may
change the characteristics of the SSR.
Step 4
Soldering
Automatic Soldering
1. Flow soldering is recommended for
maintaining a uniform soldering quality.
Solder: JIS Z3282 or H63A
Soldering temperature: Approx. 260°C
Soldering time: Approx. 5 s
(Approx. 2 s for first time and approx. 3 s for
second time for DWS)
Perform solder level adjustments so that
the solder will not overflow on the PCB.
Manual Soldering
1. After smoothing the tip of the soldering
iron, solder the SSR under the following
conditions.
Solder: JIS Z3282, 1160A, or H63A
with rosin-flux-cored solder
Soldering iron: 30 to 60 W
Soldering temperature:
280°C to 300°C
Soldering time: Approx. 3 s
Solder
Flux
2. As shown in the above illustration,
solder with a groove for preventing flux
dispersion.
Step 7
Coating
1. Refer to the following table for the selection of
the cleaning method and detergent.
Detergent
Boiling or dip cleaning is possible for the
SSR. Do not perform ultrasonic cleaning or
cut the terminals, otherwise the internal
parts of the SSR may be damaged. Make
sure that the temperature of the detergent is
within the permissible ambient operating
temperature of the SSR.

Note: 1. Contact your OMRON representatives
before using any other detergent. Do
not apply Freon TMC, paint thinner, or
gasoline to any SSR.
2. The space between the SSR and PCB
may be not be adequately cleaned with
a hydrocarbon or alcohol detergent.
Actions are being taken worldwide to stop
the use of CFC-113 (chlorofluorocarbon)
and 1.1.1 trichloroethane. Your understand-
ing and cooperation are highly appreciated.
1. Do not fix the whole SSR with resin, otherwise
the characteristics of the SSR may change.
2. The temperature of the coating material must
be within the permissible ambient operating
temperature range.
