MU-seriesAssembling and Installation MethodSoldering Conditions(1) Refl ow Soldering!Right fi gure shows conditions for the refl ow soldering for MU series.Please make sure that the temperatures of pin terminals +Vinand -Vout shown in right fi gure, do not exceed the temperaturesshown in right fi gure.!If time or temperature of the reflow soldering goes beyond theconditions, reliability of internal components may be compromised.Please use the unit under the recommended refl ow conditions.!With this refl ow profi le, internal solder melts down. When transportingthe unit within the refl ow oven, please do not give vibrationto the unit.!Please avoid reflow soldering after applying adhesive or coating tothe unit.!You can refl ow solder up to 1 time. Do not refl ow solder when thepower supply is mounted on the back surface of the PCB becausethe unit may drop.(2) Flow Soldering : 260C 15 seconds or less(3) Soldering Iron : maximum 360C 5 seconds or lessAA’BB’C+Vin(C)TpTxTy2Ty1*View from AboveA A’B B’Ctime(s)1.0 - 5.0C/sTy1 : 160±20CTy2 : 180±20CTy1 - Ty2 : 120s max1.0 - 5.0C/sTp : Max 245C 10s maxTx : 220C or more : 70s max1.0 - 5.0C/s-VoutMUStress to Pin Terminals!If too much stress is applied to input/output pin terminals of the power supply, internal connection may come down. If you apply stress asshown below, please keep it at 19.6N (2kgf) or less vertically.!Input/output pin terminals are soldered to the PCB internally. Do not pull or bend a lead powerfully.!If it is expected that stress is applied to the input/output pin terminals due to vibration or impact, reduce the stress to the pin terminals bytaking such measures as fi xing the unit to the PCB by silicone rubber, etc.19.6N(2kgf)or less19.6N(2kgf)or less19.6N(2kgf)or less19.6N(2kgf)or lessStrength of Input/Output Pin Terminals for MU? 301 ?MUS .
