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.

What Others Are Asking

How can I tell whether an SMT/SMD capacitor is oriented with plates horizontal or vertical?

Is there an industry standard for showing how plates in the SMT cap are oriented? How can you tell if it is a square-rectanguloid instead of being flattish in one dimension?

Why do through-hole components fail to solder correctly down onto the PCB?

I am an electrical engineer in a company. Recently I am developed a new product in lab and making a sample for further confirmation. When I solder TH component, feel a little troublesome. Any soldering expert to help?

Does anyone have any experience using zero-ohm resistors in an RF signal path to select antennas?

I’ve typically used RF switches for this purpose, but that’s also when it was necessary to allow the antenna selection to be changed “in the field”. But for cases where the antenna selection is a manufacture-time option, I’m considering simple zero-ohm resistors.
