Is aluminium foil a good substitute for kapon tape when soldering?

I want to desolder a tiny surface mount button from the motherboard of a phone. There are a lot of similarly tiny components surrounding it that I do not want to damage with heat from the soldering iron. Can I use aluminium foil in lieu of kapton tape to protect these components?

If you are using a iron, then just apply it where needed. Other nearby components won’t that that hot unless you do something really wierd.

Also, Kapton tape doesn’t protect against heat. It keeps things from getting soldered by being a physical barrier to molten solder. The reason Kapton is used instead of other tape is that Kapton can stand high temperatures. It’s also useful that solder doesn’t wet Kapton.

Can we do wave solder the through hole parts without masking it?

We would like to do wave soldering for the through hole components. All through hole components are top side of PCB. Only test points, which require mask during process, are on the bottom side. So there is a extra labour cost at adding and removing the mask. Can we do wave solder the through hole parts without masking it?

What are primary and secondary sides of PCB?

I am designing a 2 layer PCB with components on both side of it. SMT components are one one side of PCB, but TH (through hole) components are on both sides. I need to understanding something mentioned by the supplier called primary and secondary sides.
