Providing Value To Clients Through

For customized coil projects, technical requirements can be reviewed before supplier selection and quotation. Depending on the project, we also help source magnetic cores, enameled copper wire, capacitors, PCB/PCBA and specified electronic components.
Located in Dongguan, one of the world’s most concentrated electronics manufacturing regions, we work with long-term cooperative processors and suppliers. This gives our customers practical access to the local supply chain for copper wire, insulation materials, connectors and packaging.

Wireless charging works on the principle of electromagnetic induction. A transmitter coil in the charging pad generates a varying magnetic field, and a receiver coil in the device converts that field back into electric current, which is then used to charge the battery.
In an actual project, the parameters that matter most are coil inductance, coil geometry, operating frequency, output power and temperature rise. The alignment between the transmitter and receiver coils, the ferrite shielding and the PCBA design all affect charging efficiency and heat.
If you are developing or sourcing a wireless charging coil or PCBA, share your target power level, coil dimensions, inductance value and application. We will review the requirements and evaluate suitable supply options.
