Need some soldering advice for beginners
So i’ve recently started messing around with microsoldering. I’ve mostly been practicing on dead or iCloud devices. I’m having a few big issues.
1) Is there any good way to easily remove under-fill?
2 My solder just sticks to the board in a big clump. Not to it’s respective pads, just in a big ball. I can wick it away but it just happens again when I try and reball / clean the pads. I’m using plenty of flux so I don’t see that as being the problem but then again I know absolutely nothing about this.
And finally does the orientation of FPC connectors matter? I don’t think it would but like I said I know nothing. Any and all help would be appreciated. Even if it has nothing to do with these specific questions anything is helpful. At this point I break everything I touch hahaha. Thank you all :)
