Test Condition: 48 Vin, 5 V, 20 A output, Cout = 500 µF ceramic + 2200 µF electrolytic The SRSB-80T05x modules are designed to be compatible with a Paste-In-Hole assembly process. The suggested Pb-free solder paste is Sn/Ag/Cu(SAC). The recommended reflow profile using Sn/Ag/Cu solder is shown in the following. Recommended refl ow peak temperature is 245°C while the part can withstand peak temperature of 260°C maximum for 10seconds. This profile should be used only as a guideline. Many other factors influence the success of SMT reflow soldering. Since your production enviro nment may differ, please thoroughly review these guidelines with your process engineers.
