APPLICATION GUIDELINES
Automatic Wave Soldering
* Wave 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/s | 3~5s |
Hand Soldering
* Keep the tip of the soldering iron clean.
| Solder lron | 30W or 60W |
|---|---|
| lron Tip Temperature | Approx. 350°C 662°F |
| Solder Time | Within 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.
