Most of the Bluetooth devices actually have range of maximum connectivity of almost 30 feet. but this range may reduce when any type of barrier comes between the devices.

The technology of Bluetooth actually allows all of today’s computer devices and portable mobile devices to connect to the internet without wireless and cable access to the Internet.

Moreover, it can quickly exchange all the wireless information among several devices. These devices generally include,

Basically, it is a wireless communication with low-power short-range.

Furthermore, it is extremely low cast communication tool.

In this communication protocol technology operates at just 2.4GHz range.

It is actually a radio-frequency range.

In fact, it is similar to several different contracts of communication in which Wi-Fi protocol is also include.

When you have to connect two devices via Bluetooth technology, you have to exchange the unique codes of these devices.

Hence, if you want to communicate with any other Bluetooth device you have to get approval from the other user.

What is a Bluetooth PCB Circuit in the Bluetooth Headphone PCB Assembly?

Bluetooth headphone PCB assembly actually depends on the bluetooth PCB circuits.

Bluetooth circuit is actually the center part of the Bluetooth technology. Moreover, it generally consists the components like:

  • Source of power
  • Integrated circuit
  • Capacitors.

The IC consists a voltage regulator and charger. The module of Bluetooth includes information on the setting and configuration.

In fact, the Bluetooth technology exchanges the method of cable and wire communication between devices.

How Bluetooth Circuits in the Bluetooth Headphone PCB Assembly Work?

Fortunately, because of the development of technology Bluetooth technology makes use of low power signals in order to avoid any interruption from the second device.

Hence, all the Bluetooth devices can work properly inside the range of 10 meters.

But if you will go out of this range the connection will be lost.

A Bluetooth circuit board actually includes many PCBs which has multiple components like,

  • Resistors
  • Diodes
  • Capacitors

The PCB can be assembled in Bluetooth headphone PCB assembly into 2 layers.

These 2 layers are present on both of the sides of a plate.

The PCB chip actually processes all the signals which have fetched from the antenna.

And after fetching the signals this chip generates an output.

In fact, the complete circuit board in the Bluetooth must have an antenna. Basically, this antenna helps to receive and send the whole information.

A Bluetooth circuitry should contain at least two inductors.

The basic job of these two inductors is to fine tune the impedance of antenna in order to enhance the best performance.

In the speaker, there is also another auxiliary circuit board.

Furthermore, it connects power button, audio cable and USB power supply. There are 2 LEDs in the auxiliary board.

The resonance frequency can be lower by the presence of a PCB close to the antenna.

Hence, manufacturers recommend that whole thickness of the PCBs which have to use in the Bluetooth must be about 1,6mm.

In the bluetooth headphone PCB assembly design, we always recommend that you should not plot any type of metal like, copper near the restricted area.

This restricted area has marked with GND, and that GND pins which need to be connected to the plane.

What are the Features of Bluetooth Circuit in the PCB Assembly Design?
