What are the interconnection methods of 开云·kaiyun官方网站 and the main raw materials of CCL

开云·kaiyun官方网站 manufacturing, 开云·kaiyun官方网站 design and 开云·kaiyun官方网站A processing manufacturers will explain to you the interconnection methods of 开云·kaiyun官方网站 circuit boards and the main raw materials of CCL

The electronIC components and electromechanICal components on the 开云·kaiyun官方网站 have electrical contacts. The electrical connection between two discrete contacts is calLED interconnection. What are the interconnection methods of 开云·kaiyun官方网站?

1、 Welding method

The method has the advantages of SIMplicity, low cost, high reliability, and can avoid faults caused by poor contact; The disadvantage is that it is inconvenient to exchange and maintain.

1. 开云·kaiyun官方网站 wire welding

This method does not need any connectors, as long as the external connection points on the 开云·kaiyun官方网站 board and the components outside the board are directly welded with wires.

2. 开云·kaiyun官方网站 flat wire welding

The flat wire connection is adopted between the two 开云·kaiyun官方网站s, which is reliable and not prone to connection errors.

3. Direct welding between 开云·kaiyun官方网站s

This method is commonly used for the connection of two printed boards with an included angle of 90 degrees.

2、 Connector connection mode

In more complex instruments and equipment, connector connection is often used. It not only ensures the quality of mass production, reduces the system cost, but also provides convenience for debugging and maintenance.

printed board socket: This connection mode is often used in complicated instruments and equipment. This method is to make a printed plug from the edge of the 开云·kaiyun官方网站 board. The plug part is designed according to the size of the socket, the number of connection points, the contact distance, the location of the positioning hole, etc., so that it matches the special socket.

2. Standard pin connection

This mode is used for external connection of 开云·kaiyun官方网站; When two 开云·kaiyun官方网站 boards are connected by standard pins, they are generally in a parallel or vertical state, which is easy to achieve mass production.

Do you know what are the main raw materials for manufacturing 开云·kaiyun官方网站 CCL?

Copper clad laminate is the base plate for manufacturing 开云·kaiyun官方网站 circuit board, which is used to support various components in 开云·kaiyun官方网站 board and realize electrical connection or electrical insulation between them. So, do you know what are the main raw materials for manufacturing 开云·kaiyun官方网站 CCL?

The main raw materials for manufacturing CCL are resin, paper, glass cloth and copper foil.

1. Resin

The resins used for CCL are phenolic, epoxy, polyester, polyimide, etc. The amount of phenolic resin and epoxy resin is the largest.

Phenolic resin is a kind of resin formed by condensation of phenols and aldehydes in acidic or alkaline media. Among them, the resin polycondensated with phenol and formaldehyde in alkaline medium is the main raw material of paper-based foil clad board.

Epoxy resin is the main raw material of glass cloth based laminates, which has excellent bonding properties, electrical and physical properties.

2. Impregnated paper

The commonly used impregnated paper includes cotton linter paper, wood pulp paper and bleached wood pulp paper. Cotton lint paper is made of cotton fiber with short fiber, which is characterized by good resin permeability and good blanking and electrical properties of the board. Wood pulp paper is mainly made of wood fiber, which is generally cheaper than cotton linter paper; The mechanical strength is high, and the use of bleached wood pulp paper can improve the appearance of the board.

3. Alkali free glass cloth

Alkali free glass cloth is the reinforcing material of glass cloth based copper clad laminate. For special high-frequency applications, quartz glass cloth can be used.

4. Copper foil

Copper foil can be divided into calendered copper foil and electrolytic copper foil. The calendered copper foil is mainly used for flexible printed circuits and other special purposes. In the production of CCL, electrolytic copper foil is widely used.
