The circuit board plays a very important role in the entire electronic product, so what exactly is it? Simply put, it is designed to meet the requirements of high density and compressed space. Many conductive lines are gathered and pressed onto a single board, and various components are assembled and soldered onto this board. It can be seen that it integrates all electronic components. When electronic products show functional problems, the first thing to be questioned is the circuit board. So how is the circuit board made? Today in Jiangmencircuit board manufacturerLet me give you a detailed introduction.

1. Prepare copper-clad board, epoxy resin board is one of the commonly used boards. Drill holes on the copper-clad board and manufacture it according to the orientation of the circuit board specification diagram.

2. Electroplating involves using chemical copper to conduct the holes, so that the circuits on both sides can be connected as a whole.

3. Make a circuit on the copper plate. This process is also known as graphic transfer, which involves removing excess copper according to the planned route and making copper wires on the copper surface.

4. The next step is to do solder mask, also known as solder mask, which has the effect of protecting the board and circuit.

5. Regarding characters, also known as text, they are the identification of components assembled on a circuit board. When dismantling one's desktop computer, one can see such a board with text, which is the circuit board we need, also known as PCB.

6. After the circuit board is made, the dimensions need to be defined. Now we enter the cutting process, also known as molding. It was cut into small pieces and its electrical performance was tested to see if it could conduct and if it was useful after being powered on.

After completing the above process, the circuit board is basically manufactured. After the circuit board is tested, its appearance needs to be inspected to see if there are any defects, and then packaged, boxed and loaded onto the vehicle.
