APPLICATION GUIDELINES

Automatic Soldering
* Flow solder is the optimum method for soldering.
* Adjust the level of solder so that it does not overflow onto the top of the PC board.
* Unless otherwise specified, solder under the following conditions depending on the type of relay.

Preheat time
20°C-100°C		Rising slope
20°C-120°C		Decreasing slope
Peak-150°C		Welding temperature
255°C-265°C
90±5 seconds＜3°C/s＜4°C/s3~5s

Hand Soldering
* Keep the tip of the soldering iron clean.

Solder lron30W or 60W
lron Tip TemperatureApprox. 350°C 662°F
Solder TimeWithin approx. 3 seconds

* Immediate air cooling is recommended to prevent deterioration of the relay and surrounding parts due to soldering heat.
* Although the sealed type relay can be cleaned, avoid immersing the relay into cold liquid
(such as washing solvent) immediately after soldering. Doing so may deteriorate the sealing performance.
