The necessity of purchasing anti-static products needs to be judged in combination with specific usage scenarios and needs.
The following is a summary of its core value and application scenarios:
I. Hazards of static electricity
Damage to electronic equipment
Electrostatic discharge (ESD) may directly break down electronic components (such as CMOS chips, capacitors), causing potential equipment failure or shortened life, especially for precision instruments, semiconductor devices, etc. Significant threats.
Industrial production risks
In industries such as electronic manufacturing, pharmaceutical biology, and semiconductors, static electricity may cause batch product defects or experimental errors, directly affecting production yield.
Human discomfort and safety hazards
Although daily electrostatic discharge is not fatal, repeated electric shocks may cause anxiety and even lead to operational errors (such as static electricity igniting oil and gas when refueling).
II. Applicable scenarios and product selection
1. Professional field rigid demand
Electronic maintenance/manufacturing : Anti-static wristbands need to be used with a grounding system, which can stably control the human body voltage below 50 volts and reduce the electrostatic accident rate by more than 90%;
Clean room/laboratory : It must comply with ISO or ESD standards and combine anti-static clothing, ion blowers, etc. to form a complete electrostatic protection system.
2. The practicality of daily protection
High-value equipment operation: When replacing a mobile phone screen or assembling a computer, a properly grounded wired bracelet can provide basic protection;
Dry environment to relieve static electricity: Anti-static spray, conductive fiber clothing, etc. can be used to reduce static electricity accumulation in winter, but wireless bracelets will have limited effect if they are not effectively grounded.
3. Identification of IQ tax products
Invalid type: Wireless bracelets that claim to release static electricity through the "ionization principle" have an elimination efficiency of less than 30% when the humidity is less than 40%, and the actual effect is no different from that of ordinary metal bracelets;
Effective product standards: It must contain a 1 megohm resistor grounding wire and be correctly connected to the water pipe or socket ground wire. The material must be highly conductive silicone or metal fiber.
3. Comprehensive suggestions
Anti-static products are not "necessities", but they are irreplaceable for specific groups of people and scenarios:
Three types of necessary users: electronic engineers, semiconductor practitioners, and those who frequently operate highly sensitive equipment need to be equipped with professional-grade equipment;
Cautious consumers: daily users should give priority to anti-static through physical means such as increasing environmental humidity and wearing cotton clothes. If you need to buy, you need to verify the grounding performance of the product.
In short, the value of anti-static products depends on the scene adaptability and product quality. Reasonable selection can avoid the "IQ tax" trap.
