II. Main features of Multichannel LCR meter MICROTEST 9332 (PCB/FPC application)

About wireless charging:

With inductive coupling technology, the charger transfers energy to a electric device, such as a mobile phone.
The mobile phone will charge the battery by receiving energy, so there is no need to use wires between charger and device.

Wireless Charging
Charging Coil Tx	Charging Coil Rx

Enamelled round winding wire	Small, thin and low accept winding product is most suitable for smart wearable device. Wearable devices want to be thinner and lighter, so Charging Coil tend to be made by FPC. Because the material characteristic of copper foil easy to be destroyed during process.

Capacitance become bigger:

→ Etching process not enough, distance between wires will become large.

Resistance become bigger:

→ Etching process not well, wires will become slender.

Quality of coil is also a key factor effect resonance frequency:

→Diameter of coil wire

→Diameter and number of turns of coil

→Material of magnetic component (increase induction intensity).

The closer of working frequency and resonance point, the better transmission efficiency:

Inductance deviation:

Poor processes will result in the resistance value of the copper foil circuit to increase as well as the parasitic capacitance; these will all cause high levels of losses to the inductance.
Inductance offset causes a direct impact to the resonance frequency that is the key for wireless charging; once the resonance frequency curve has been offset, it may result in the risk of NG for products delivered to the module factory to test their functionalities.
