Anti-static Ion Fan
Actual action and monitoring of anti-static ion fan
Due to the use of ion fans, manufacturers can accept the fact that some insulating materials appear in their EPA. Because the ion fan system continuously neutralizes any charge buildup that may occur on the insulator, 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 generate electrostatic charge is to use an ion blower (also known as an ionizer)—a device that blows out an ionized air stream in the work area to neutralize any buildup on the insulating material. Charge.
There are also indoor ion fans, but now they are mainly used in the clean room environment.
The choice depends on the size of the area that needs to be protected. The desktop ion fan will cover a single working surface, while the over-the-top ion fan will cover two or three. Another advantage is that the ion fan also prevents dust from electrostatically attaching to the product and may degrade the appearance.
However, without proper testing and monitoring of the effectiveness of ESD equipment, no protection plan is perfect. State-of-the-art ESD control and ionizer experts report examples of manufacturers that use failed (and therefore useless) ESD devices without knowing their failure.
To prevent this, in addition to standard ESD equipment, ESD suppliers offer a variety of constant monitors that automatically alert if a performance is out of specification. The monitor can be used as a stand-alone unit or connected together in a network. There is also network software for automatic data collection that displays system performance for operators and workstations in real time.
The monitor simplifies the ESD program by eliminating many daily tasks, such as ensuring proper measurement of the wristband every day, balancing and proper maintenance of the ion fan, and no damage to the workbench grounding point.
In ESD protection, the time and money invested in the right equipment and improved safety procedures will be rewarded by an increase in the corresponding pass rate.
