Reflow Soldering Curve Of SMD Disk Metal Oxide Surface Mount Varistor For LED Lighting

SMD varistor is soldered with lead-free solder, and the silver side of the chip is used as one of the soldering surfaces. Therefore, the above reflow soldering curve is recommended for soldering. If the above conditions (265 ℃/20S-40S, in and out time 8~10 minutes) are exceeded, soldering , Please pay attention to the problem of tin melting and the virtual silver electrode on the bonding surface.
