Wireless Communication Systems PCB Assembly

A communication system refers to all the equipment and transmission media that complete the communication process. When wireless methods are adopted, a wireless communication system is formed. Wireless communication refers to a communication method that transmits information through radio waves or other electromagnetic waves without physical connection lines or wires. Its principle is based on converting the original information into a wireless signal, and then transmitting it through media such as air to the receiving end, and then converting it back into recognizable information again. A wireless communication module is a device that sends or receives electromagnetic wave signals and converts them into information that we can understand. It is mainly used in the Internet of Things to enable the transmission of information among various terminal devices and to give smart devices the information interface of the Internet of Things.

There are various options for wireless communication modules. Common wireless communication technologies include:

Wi-Fi: Suitable for high-speed data transmission and device networking. Commonly used modules include ESP8266 and ESP32

Bluetooth: A short-range wireless communication technology, widely used for communication between personal devices.

Zigbee: A low-power, short-range wireless technology, suitable for Internet of Things devices.

LoRa: A long-range, low-power wireless technology, suitable for applications with low data rates.

NRF24L01: A low-power 2.4GHz wireless transceiver module, suitable for wireless sensor networks and short-range communication.

Select the appropriate communication technology:

If low power consumption and long-distance communication are required, LoRa or Zigbee might be good choices.

If high-speed data transmission is required, Wi-Fi or Bluetooth is more suitable.

PCB is one of the important components in the electronics industry. Almost every kind of electronic device, from small electronic watches and calculators to large computers, communication electronic equipment, and military weapon systems, as long as it has electronic components such as integrated circuits, to achieve electrical interconnection between each component, printed circuit boards must be used. The printed circuit board is composed of an insulating base plate, connecting wires, and solder pads for assembling and soldering electronic components. It has the dual functions of conductive circuits and insulating base plates. It can replace complex wiring and achieve electrical connections among various components in the circuit. It not only simplifies the assembly and soldering work of electronic products but also reduces product costs and improves the quality and reliability of electronic devices. Printed circuit boards have good product consistency. They can adopt standardized designs, which are conducive to achieving mechanization and automation in the production process. At present, printed circuit boards have been extremely widely used in the production and manufacturing of electronic products, especially in wireless communication systems.

When designing the printed circuit board for a wireless communication system, it should be noted that a low-impedance power supply and a ground wire with minimal noise radiation need to be provided. It is required to use a double-sided PCB board and place the ground plane at the bottom layer to reduce radio radiation and crosstalk. The bypass capacitor should be as close as possible to each power supply pin VDD. Never connect the PCB through holes to the complex ground wire. To reduce the distributed capacitance in the circuit, the occurrence of parallel lines should be avoided. The shorter the line, the better. To prevent coupling, each of its components should be independent. Use the grounding wire to isolate each signal; The transmitting antenna can be printed on a PCB.
