Re: Apple MacBook Pro Mid-2017 A1706 - C7490 Capacitor Help
There has to be a local cell phone repair shop near by. Often in malls. There are relatively low cost hot air tools on Amazon but AliExpress is a better choice. We met with Best tools in HK and they are willing to sell spare parts to service their equipment which was a bonus for us.
As the PCBs have multiple layers, a higher temp of the tool is helpful. An underside pre-heater is also helpful for bga rework.
You only need flux and technique to place these down. Suggest to drown the part with a drop of flux and start with low air pressure from the top of the part. As the flux triggers, the part will swim onto the pad. Do not move the hot air tool and the part will be soldered. Remove the tool and allow the part to naturally cool.
Practice on donor or dead boards.
PS: Love love love our new 4k microscope from Hayear. Will post details and sample screens in the future.
