Solder Reflow and Rework Recommendations
Profile Feature Pb-Free Assembly Average Ramp-Up Rate (Tsmax to Tp) 3° C/second max Preheat : Temperature Min (Tsmin) 150° C Temperature Max (Tsmax) 200° C Time (tsmin to tsmax) 60-180 seconds Time maintained above: Temperature(TL) 217° C Time (tL) 60-150 seconds Peak/Classification Temperature(Tp) : 260° C Time within 5° C of actual Peak : Temperature (tp) 20-40 seconds Ramp-Down Rate : 6° C/second max. Time 25° C to Peak Temperature : 8 minutes max Solder Reflow Due to “lead free / RoHS compliant ” construction of these PTC devices , the required Temperature and Dwell Time in the “ Soldering ” zone of the reflow profile are greater than those used for non-RoHS devices. 1. Recommended reflow methods; IR, vapor phase oven, hot air oven. 2. Not Recommended For Wave Solder / Direct Immersion. 3. Recommended paste thickness range – 0.20 – 0.25mm. 4. Devices are compatible with standard industry cleaning solvents and methods. 5. MSL: 2a (According to IPC J-Std-020). Caution If reflow temperature / dwell times exceed the recommended profile, the electrical performance of the PTC may be affected. Rework: MIL-STD-202G Method 210F, Test Condition A.
