6 / 8 page 326 High Frequency Relay G6K-RF Precautions ■ Recommended Soldering Method 3. The thickness of cream solder to be applied should be between 200 and 250 μm and the land pattern should be based on Omron’s recommended PCB pattern. To maintain the correct soldering joint shown in the following diagram, we recommend applying solder using the soldering conditions shown above. Check the soldering in the actual mounting conditions prior to use. ■ Precautions for correct use For general precautions, refer to Omron’s Relay Technical guidelines, contained in Omron’s relay catalog. Relay Handling Do not unpack the relay until ready to mount it. Use the relay as soon as possible after opening the moisture-proof bag. Otherwise, the terminals may tarnish and seal failure may occur after the solder process. When washing the product after soldering, use a water-based or alcohol-based solvent. Keep the solvent temperature below 40 °C. Do not put the relay in a cold cleaning bath immediately after soldering. Operating, Storage Environment If the relay is stored for a long time in an adverse environment with high temperature, high humidity, organic or sulfide gases, then sulfide or oxide films will form on the contact surfaces. These films may result in unstable contact, contact problems or function problems. Therefore, operate, store or transport the product under specified environmental conditions. 1. Use in locations where the relay is not exposed to corrosive gas such as hydrogen sulfide gas or salty air. 2. Use in locations where no visible dust exists. 3. Use in locations where the product is not exposed to direct sunlight, rain or snow. 4. Do not apply force to the product which may result in deformation or change in quality of the product. Coating The relay mounted on the PCB may be coated or washed, but do not apply silicone coating or detergent containing silicone, otherwise, the silicone coating or detergent may remain on the surface of the relay. Latching Relay Mounting Make sure that excess vibration or shock doesn’t set or reset the relay during normal operation. The relay is shipped in the ‘reset’ position. Shock or vibration during shipping may require the application of a reset signal, prior to operation. Claw Securing Force During Automatic Mounting During automatic insertion of relays, make sure to set the securing force of each claw to the following so that the relay’s characteristics will be maintained. Maximum Allowable Voltage The maximum allowable voltage of the coil can be obtained from the coil temperature increase and the heat-resisting temperature of the coil insulating sheath material. (Exceeding the heat-resisting tem- perature may result in burning or short-circuiting.) The maximum allowable voltage also involves important restrictions which include the following; • Must not cause thermal changes in or deterioration of the insulating material, which may result in films developing on the contacts. • Must not cause damage to other control devices. • Must not cause any harmful effect on people. • Must not cause fire. Therefore, be sure to use the maximum allowable voltage as specified in the catalog. As a rule, the rated voltage must be applied to the coil. A voltage exceeding the rated value, however, can be applied to the coil providing that the voltage is less than or equal to the maximum allowable voltage. It must be noted that continuous voltage application to the coil will cause a coil temperature increase which may affect characteristics such as electrical life and coil insulation. Consider using a latching relay instead of a non-latching relay with a continuous voltage applied to the coil. 1. Temperature Profile for Lead Solder (Measured at the PCB) 2.
