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.

Where should I store PCB?

I have received the final prototypes from manufacturer and all is good after our checking. And we want to keep it well. Do you have any tips about that?

What do we need to check before releasing a PCB design?

After making efforts in a period, I finally finish my PCB design. Next step is releasing them to factory for production. To be honest, I don’t want any mistake on my file which may interrupt further prodution process. So what points should I pay attention when I double-check my design?

How do you mount electronics on a vehicle chassis safely?

I want to implement a control system I designed for a light electric motorbike. I would like to mount it as professionally as possible on the chassis. It consists of a power system pcb and a SAMC21 development board which I’ll merge later once this all works properly. I have tried screwing it directly on the aluminium chassis but have found that shocks and vibrations from the horn disturbed the system or even destroyed it upon large shocks. Is there a specific way car and motorcycle manufacturers mount their electronics to make their system as robust as possible?
