Make sure that the power supply is reliable. The extension line and feeder quality are poor or too long, so the bit error rate is high;7 Production guidance7.1 Reflow soldering temperatureProfile Feature Curve characteristics Sn-Pb Assembly Pb-Free AssemblySolder Paste Solder paste Sn63/Pb37 Sn96.5/Ag3/Cu0.5Preheat Temperature min （Tsmin） M in preheating temp. 100℃ 150℃Preheat temperature max (Tsmax) M x preheating temp. 150℃ 200℃Preheat Time (Tsmin to Tsmax)(ts) Preheating time 60-120 sec 60-120 secAverage ramp-up rate(Tsmax to Tp) Average ramp-up rate 3℃/second max 3℃/second maxLiquidous Temperature (TL) Liquid phase temp. 183℃ 217℃Time（tL）M aintained Above（TL） Time below liquid phase line 60-90 sec 30-90 secPeak temperature（Tp） Peak temp. 220-235℃ 230-250℃Aveage ramp-down rate（Tp to Tsmax） Aveage ramp-down rate 6℃/second max 6℃/second maxTime 25℃ to peak temperature Time to peak temperature for25℃ max 6 minutes max 8 minutes
