Question

How do ordinary metals form electrical paths in PCBs?

Answer 1

Common metals form electrical paths in PCB mainly through the following steps:

1. Make metal core PCB: Use metal materials (such as aluminum, copper, iron, etc.) to make PCB boards, including circuit boards, copper substrates, iron substrates, etc.

2. Metalized hole production: Metalized holes are made on the PCB board so that the metal material forms a continuous conductive path.

3. Metal connection: Connect metal components (such as resistors, capacitors, ICs, etc.) to the metalized holes on the PCB board through welding, crimping, riveting, etc. to form an electrical path.

4. Testing and verification: Test and verify the produced PCB board to ensure that the conductive performance and stability of the metal electrical path meet the requirements.

In summary, forming electrical paths in a PCB with ordinary metals requires steps such as making a metal core PCB, making metallized holes, metal connections, and testing and verification. These steps require professional PCB design and manufacturing skills to ensure that the electrical paths produced have high reliability and good conductive properties.

Answer 2

Signal transmission: The metal lines on the PCB transmit signals between electronic components. These signals can be electrical, analog, or digital.

Answer 3

Solder is the metal that creates the electrical connection between the PCB surface and the electronic components. As a metal, solder also acts as a strong mechanical adhesive. Wires and Copper Foil. Wires are metal tracks on a PCB that connect circuit paths between electronic components. They are usually made of copper foil, formed through processes such as etching or added plating.

Electrical connections: The wires and metal lines on the PCB are used to connect electrical signals between electronic components (such as resistors, capacitors, integrated circuits, etc.). Wires are printed, etched or added to achieve circuit connections.
