Unless you got eyes like an eagle you need a good microscope. Most of all practice on old boards and experiment with heat airflow and time on the component size as a reference for future size components. It's hard & needs a steady hand when dealing with such small components. Practice makes perfect Br |

Try and look on u-tube for some videos of their equipment, solder compound / flux used as an example. It takes time and patients Good luck with age comes knowledge Br |
