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

Is there a standard that defines that the marking actually has to indicate the cathode?

SMD LEDs normally have some kind of marking. We recently had 300 PCBs manufactured where each had 32 LEDs of those. However, the assembly house placed all LEDs in reverse. The cathode is not consistent with the marking of the actual LED that was mounted. Is there a standard defining this?

Why the PCB is cold, but LED bulbs are still hot?

I have a THERMAL problem when designing a power LED ALUMINUM PCB. I have 10 5W UV power LEDs.Coldwater flows through water heat sink continuously. The problem is the PCB is cold, but LED bulbs are still hot? Can anyone give me some advice.
