Hi, I am quite new to mobile servicing. I want to use smd rework station. While doing so, there are much opportunities for the damage of nearby components . Are there any ways to avoid damaging such nearby components? Thanks.
Yep, there two ways that I use to shield surrounding components of what you are heating up. Apply Kapton (Yellow non-conductive) tape to surrounding componentsUse thick metal objects that absorb heat well like a penny / coin (if needed) Pre-heating the board to something like 80°C will make it easier to remove the component being heated. Avoid using a small nozzle as they are prone to blowing surrounding components away for the heat gun and don’t heat components for too long when putting them on to the board. For a lot of my re-work I use 380-480°C depending on the heat required, this will vary between hot air stations so might want to practice removing and putting back SMD components / BGA components on dead boards first.
