What is the role of the ion blower in the SMT industry and the principle of static elimination?
The ion blower in the SMT industry is a device used to eliminate static electricity. It can prevent static electricity from damaging electronic components during the SMT production process. The measurement of SMT ion blowers is usually carried out using an electrostatic eliminator performance test system. The system can measure the ion balance, ion current, ion density, ion wind speed and other parameters of the ion blower.
Ion balance refers to the equal number of positive ions and negative ions generated by the ion blower, which is an important indicator of the ion blower. Ion current refers to the flow speed of ions generated by the ion blower in the air, ion density refers to the concentration of ions in the air, and ion wind speed refers to the flow speed of ions in the air.
Principle of static elimination of ion blower
The principle of static elimination of ion blower is to achieve the purpose of eliminating static electricity by generating a large number of positive and negative ions and neutralizing the charge on the surface of the object. The ion blower is mainly composed of a high-voltage power supply, an ion emitter and a fan. The high-voltage power supply generates a high-voltage electric field, and the ion emitter generates a large number of positive and negative ions under the action of the high-voltage electric field. The fan blows the ions to the surface of the object to neutralize the charge on the surface of the object, thereby eliminating static electricity.
