How to prevent the insulation material from generating static electricity
Manufacturers of electronics and semiconductor plants can accept the fact that some insulating materials appear in their EPA. What kind of static elimination equipment can be used to prevent static electricity from generating insulation materials? Ion blower systems are used to continuously neutralize any charge buildup that may occur on insulators, so they are a reasonable investment for any ESD program.
There are two basic forms of ion fan equipment in standard electronic assembly: The most effective way to neutralize assembly equipment and surfaces that can generate electrostatic charges is to use an ion fan (also called an ionizer)-a device that blows out ionized air Flow in the work area to neutralize any charge accumulated on the insulating material. There are also indoor ion fans, but now they are mainly used in clean rooms for electronics. The choice depends on the size of the area to be protected. The desktop ion fan will cover a single working surface. If the hanging ion fan will cover two or three stations. Another advantage is that the ion fan can also prevent dust from electrostatically attaching to the product, which may degrade the appearance. However, without proper testing and monitoring of the effectiveness of ESD equipment, no protection plan is complete. Good ESD control and ionizer experts report examples of manufacturers who use failed (and therefore useless) ESD equipment without knowing its failure. To prevent this, in addition to standard ESD equipment, ESD suppliers also offer a variety of constant monitors that automatically alert if an item exceeds its specifications. The monitor can be used as a stand-alone unit or connected together in a network. There is also network software for automatic data acquisition, which displays the system performance of operators and workstations in real time.
The air inlet and outlet air cleaning nets and ionization outlet nets of the ion fan should be kept clean to prevent obstructing the airflow. They can be cleaned with a soft brush or compressed air. Ion balance test, use plate load monitor to measure, or use ion tester to measure ion balance (residual voltage). Static elimination time test, use static analyzer or load monitoring board to measure static elimination time. The ion fan is calibrated, and the output design of the ion amount is stable and fixed. It may be affected by factors such as voltage fluctuations, ambient air dryness and humidity, etc., and a shift in ion balance (residual voltage) is formed. Offset standard: 0V ± 1
