1. Reflow solder conditions *Solderability When flux-mounted terminals are immersed in solder at following conditions, at least 95% of the surface should be covered by solder. Conditins leaded process : 2305C for 30.5 seconds lead free process : 2605C for 30.5 seconds *Solder heat resistance No abnomalities under solder conditions of leaded process : 2305C for 5 seconds lead free process : 2605C for 5 seconds 2. Rinsing After Soldering, you should rinsing away the excess flux. Any commercially available rinsing agent may be used. 3. Other Precautions Perform soldering at as low a temperature as possible and for as short a time as possible. Make sure that the silver electrode of resonators is not covered by solder. Avoid applying external forces to terminals such as by bending or cutting them. 4. Iron Soldering Perform iron soldering with iron at following conditions. Conditins leaded process : 3505C for 5s. Max. lead free process : 3905C for 5s. Max.
