on the leads of each device is 100% pure tin electroplate. The device is suitable for lead-free applications and can withstand surface-mount soldering at up to 255°C

(±5°C). In addition, it is backward compatible with conventional tin-lead soldering processes. This means that the electroplated tin coating can be soldered with tin-

lead solder pastes at reflow temperatures of 220°C to 235°C.
