I know that this theme is not about MCU, but I don't know to which group belongs. I need hand-solder Lion charger MC34674, but I don't know how. I try solder 3 pieces but unsuccesfully. When I complete 2 PCB with this IC, after supply voltage and battery connection, the one LED was turned on, VBAT was 3.78V (after battery disconnect was this voltage around 2.5V), but Vref was still 0V and I don't know if this was caused unsuccesfull soldering or other error. Please any idea how proprely solder this IC?




PS: I'm sorry for my poor english.
