① Connector, or CONNECTOR. Also called the connector, the connector. It is a kind of component that electronic engineering technicians often contact with. Also known as connector, plug and socket. Generally refers to the electrical connector. That is, a device connecting two active devices to transmit a current or a signal.
② Connection is a connecting electronic circuit positioning connector, is composed of two parts, namely plug, and connector, general state can be completely separated, the switch and the connector in the contact state change, realize the circuit conversion, and its essential difference is that the connector only insert the plug two states, the switch can realize circuit conversion on the body, the connector contact of a fixed corresponding relationship, therefore, the connector can also be called a connector.
③ Terminal terminal, English name Terminal (terminal). It is a kind of accessory product used to realize the electrical connection, and the industry is divided into the category of the connector. The terminal is used to facilitate the connection of the wire, it is actually a metal sheet sealed in the insulating plastic, with holes at both ends that can be inserted into the wire. Terminal terminal can be divided into WUK terminal, European terminal series, plug and plug terminal series, etc.
What are the characteristics of the SMT technology?
SMT is short for Surface Mounted Technology (Surface mount Technology), which is currently the most popular technology and process in the electronic assembly industry. It compress traditional electronic components into only one tenth of devices to achieve automatic assembly of electronic products with high density, high reliability, small size, low cost and production. This panel is called: SMY equipment (also known as SMC, chip equipment), the process of making the original suitable for printing is called SMT, and the related assembly equipment is called SMT equipment.
SMT characteristic:
1. High-density assembly, light weight, small volume of electronic products, after the general use of SMT, the volume of electronic products reduced by 40% -60%, weight reduced by 60% -80%;
2. High reliability, strong vibration resistance, low solder joint defect rate;
3. Good high frequency characteristics, reduce electromagnetic and radio frequency interference;
4. Easy to automation, improve production efficiency and reduce cost by up to 30% -50%. Save on material costs, energy, equipment, manpower, and time.
