CEM3 or FR4 PCB, which is the lightest material?

There is nothing about weight in the substrate datasheets I found. Between CEM-3 or FR4, which is the lightest material ? What is the average weight by surface for CEM-3 boards ?

CEM-3 is lighter than FR4,the average weight is about 3.5KG/sqm. but now most of PCB manufacturers less use CEM-3 material to make PCB,almost use FR4 material.

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?

How do I use two antennas with a single Bluetooth module? (BLE repeater)

I am working on a project that uses small Bluetooth low energy (BLE) beacons to track important items. Is there a way to connect two antennas to a single BLE module that could either listen/broadcast on both antennas or multiplex between the two? Or any other idea?
