Make sure you test (push/pull) the switches on the other 19 boards to see if they come off easy. In my case of 12 boards 3 switches were loose in the package and 5 more came off with that test. Admittedly these were ‘large’ SMD switches, but still I expected more from a professional (vapor phase?) solder process.
Aisler offered to do the rework and sent me labels to stick on a package. However, as these boards contained an unobtainable microcontroller I decided that doing the rework myself made more sense in this case. They later credited an amount which settled the issue for me.
(TBH, if only one switch, I would always do the rework myself. Finding a box to fit the PCB takes more time )
I have a colleague at my university who might be able to help with the repair. This is my first experience with SMD parts on a board and the re-attachment process looks delicate without the proper equipment.
Any tutorials/videos you could recommend on a DiY rework process? What equipment is needed?
I will see how Aisler responds to my most recent ask for help.
Difficult to say without knowing the switch, but a fine iron and some thin solder usually do it for these types of component.
That said, the right equipment is mandatory and usually not cheap, although, for incidental soldering jobs you could look at an iron like the TS100 or derivatives. That could certainly be used for a job like this.
