Why is wireless charging not ubiquitous?

Wireless charging is so convenient for user because it doesn’t need any wire, but it is not so popular as market. It must be some reasons in supplier side, isn’t it?

Two key reasons.

The underlying chips that make both the transmission and reception of wireless power are very expensive. The PCB (circuit boards) and metals used are very common, but the actual chips that do all the work are not cheap. There are few companies that offer them right now.
Wireless charging is relatively inefficient, which is why it releases a lot of heat. To minimize heat you have to do a lot of tricks including passive air cooling, as well as decently complex magnetic field compression via uniquely located magnets with the opposite polarity of the main field.

How can the amount of dielectric material affect a PCB?

I understand that the dielectric material on a PCB (i.e. FR-4) can affect the capacitance of the board. But I don’t understand why is that capacitance significant, and in what applications should the amount of dielectric material be taken into consideration?

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?

Do the scratches on the PCB have any bad effect to products?

We receive a batch of PCB with scratches from my supplier, but they think it is acceptable. I have never seen such error on even an B stock boards parts. Very confused. How do scratches affect PCB working?
