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.

What Others Are Asking

How can I handle missing solder mask opening on PCB footprint?

I have three through-hole PCBs that are missing front and back solder mask openings for two of the components. The solder mask (usually green) is covering the front and back solder pads. All other pads for all other parts are exposed. Is there a good way to remove the solder mask so that I can solder the components to the board?

Why aren’t components in DIP package shipped with straight pins?

I’ve noticed that all DIP packaged devices have pins which are at an angle other than 90∘ and need to be bent so that the angle is right for insertion into holes on the PCB or wherever. Is there any reason other than tradition for that?
