Classification of circuit boards
According to the number of layers, single-sided, double-sided and multilayer circuit boards are divided according to the circuit layer inside.
The first is the single-sided circuit board. On the general circuit board, the components are on one side of the board and the lines are on the other side. Because there are lines on only one side, we call this kind of circuit board single panel. Generally, the production of single panel is very simple and low-cost, but it can only be used in simple electronic products, and single panel can not be used in more complex electrical appliances.
Then there is the double-sided board. Of course, it is called double-sided board because it has two-sided circuits. When only one circuit of a product cannot meet the normal use, it needs this kind of circuit board with more than two or more sides to meet it. Double sided lines connect the lines on both sides through copper holes, so that different lines can be divided into different network connections to meet the needs of products.
Zui is followed by multilayer circuit board. Multilayer circuit board refers to the circuit with more than three layers in the board. Each side of the conductive graphic layer is separated by insulating materials and then pressed together. Multilayer board is widely used in complex electronic products, which provides products with the advantages of high capacity, high speed, multi-function and so on.
Distinguish according to the properties of circuit board materials
It can be divided into soft board and hard board. There are also soft and hard combination boards. Soft board is made of tough material, just like plastic shell. Hard board is made of hard material, which is difficult to break or fold. Soft hard combination board is a kind of soft and hard material, which is the combination of soft board and hard board.
You can also shine the board against the strong light. There will be no light through the multilayer board, while the light from the single and double-sided board will pass through the board. Then single panel, because there is only one line. All vias are copper free. On the contrary, for double panel and multilayer board, vias can be made with copper.
Zui's essential distinction is the number of layers of the line.
Distinction of hole attributes of circuit board
The single panel has only one circuit, and the holes inside are non-metallic holes. Electroplating is not required in the process of making the board.
For double-sided and multilayer boards, the holes inside are divided into metallized holes and non-metallic holes. Electroplating is required in the production of boards.
Application of circuit board
What kind of things will use the circuit board? General household and common electronic products and appliances, such as mobile phones, televisions and computers, induction cooker, electric rice cooker and range hood for kitchen, some chargers, remote controls and high-end products. Sophisticated aircraft, missiles, automotive equipment, medical equipment, military equipment and so on. Circuit board is normally used in products to adjust speed, control time, display and other functions. Not all electrical appliances need to use circuit boards. For example, ordinary hot kettles only boil water through electric heating, so circuit boards are not needed.
Normally, when we use the circuit board, how to choose whether to use a simple single-sided board or multi-layer board, which should take into account the functions and requirements of the product. The higher the product requirements, the higher the cost of the circuit board. The design of the circuit board will involve many required functions such as signal anti-interference, circuit layout, EMC and so on. Hangzhou jiepei focuses on the production of 1-6 laminates.
With the development of science and technology, the requirements of electronic products are higher and higher. Because the application scope of single and double-sided board is small, it is only used for simple products and can not meet the needs of the times. Therefore, it will be considered to use multi-layer circuit board to meet the functionality of products. Because of its strong economic performance and stable circuit performance, multilayer board is now widely used in a wide range of electronic products. Briefly describe the distinguishing methods and applications of circuit board layers, some of which may not be complete and specific, but I still hope to let you know and help.
