Assembly circuit refers to the printed board that forms inter-point connections and printed components on the general substrate according to the predetermined design, and its main functions are: 1. Provide mechanical support for various components in the circuit; 
2. Make various electronic components create the electrical connection of the predetermined circuit and play the role of relay transmission; 3. Mark the installed components with marking symbols to facilitate insertion, inspection, and debugging.
Printed circuit boards are mainly used in communication electronics, consumer electronics, automotive electronics, industrial control, medical, aerospace, national defence, semiconductor packaging, and other fields, of which communications, computers, consumer electronics, and automotive electronics are the four areas with the highest proportion of downstream applications, accounting for nearly 90% in total, and their prosperity directly determines the prosperity of the printed circuit board industry.
On the whole, printed circuit boards can be divided into single-sided, double-sided, multi-layer boards, high-density interconnection boards (HDI boards), flexible boards, packaging substrates, etc., among which multi-layer boards, HDI boards, flexible boards, and packaging substrates with more layers belong to varieties with relatively high technical content.
Ordinary multilayer boards are mainly used in communications, automobiles, industrial control, security, and other industries.
Common components of PCBA
The printed circuit board is the basic unit of electronic design. It is a printed circuit board that brings together different electronic components to come up with a fully functional electronic system capable of powering electronic devices. It is important to point out that the more edges a printed circuit board has, the more complex it becomes. In addition, if the board is multifaceted, it means that the gadget it drives is very advanced. Printed circuit boards have different components, which are described below.
Here are some common component types:
1. Chip/Integrated Circuit (IC): A chip or integrated circuit is one of the most common components in electronic devices. They usually come in small packages that contain multiple functional circuits and transistors.
2. Diode: A diode is an electronic component that allows current to flow in only one direction. They are used in rectification, protection, and switching circuits.
3. Capacitors: Capacitors are used to store electrical charge and release energy. They play a significant role in power supply filtering, signal coupling, and timing control.
4. Resistors: Resistors are used to limit the path of current flow and control the resistance value in the circuit. They can also be used in applications such as voltage dividers, grounding, and current sensing.
5. Inductor: An inductor is a component that stores magnetic energy and has a specific response to frequency. They play an important role in filtering, isolating, and adjusting signals, among other things.
6. Receptacles and connectors: Receptacles and connectors are used to connect other electronic components, such as sensors, displays, power supplies, communication interfaces, etc.
7. Crystal oscillator: A crystal oscillator is a component that produces a stable frequency and is commonly used in clocking, timing, and synchronization applications.
8. Sensor: A sensor is a component used to detect environmental conditions or physical quantities, such as temperature, pressure, humidity, light, etc.
These are just a few of the component types that are commonly found on PCBs. In fact, there are many other types of components, including switches, relays, transformers, amplifiers, etc., and the appropriate components are selected according to the specific circuit design and application needs.
How printed circuit boards work
PCBA is designed to provide a central hub for integrating all the electronic components in a device. Using multiple layers to create a board, conductive paths or lines can be laminated onto the substrate material. These copper traces are used to conduct electricity as circuits that are soldered to all components on the board, thus powering the device while providing insulation and safe current transfer.
Advantages of PCBA
1. Minimal space requirements: Because all electronic connections are on the board, there is no need for multiple wires to carry current and take up valuable space on the device.
2. Simplified installation and troubleshooting: All components are mounted on the PCB and clearly labelled for easy access during assembly and maintenance.
3. Simplified assembly: compared to other means (e.g., wired connection), PCBs allow for quick assembly.
4. Safe Placement and Connectivity: With a PCB, all electronic components are soldered to the board to ensure they stay in place.
5. Manufacturing efficiency: When mass production is required, PCBs are more cost-effective than other joining methods.
6. Reliable operation: The design of the PCB ensures stable operation, as the connection is made through copper wires that will not loosen.

Q: What happens to aluminium substrate panels without film?
A: It will rub off, it will oxidize easily on the potion, and it has to do with the manufacturing process as well. The production process is also different.
Q: Why are there many small holes drilled in PCBs?
A: That's an overbore, which is used to connect electrical signals from one layer to another.
Q: Is there a way to solder LED beads to an aluminium substrate by hand?
A: The most common method is to use a heating table on the aluminium substrate, when the tin melts off, you can remove the unwanted lamp beads.
