Comprehensive analysis of common anti-static measures

1. Prevent the generation of static electricity

⑴ Manipulate the static electricity generation environment

① Humidity control. Increase the temperature as much as possible without causing corrosion or other harm to equipment or products

② Temperature control. Reduce the temperature as much as possible under possible conditions, including ambient temperature and object contact temperature

③ Dust control. This is an important measure to prevent attachment (adsorption) charging

④ Floors, table and chair fabrics and workbench mats should be made of anti-static materials and properly grounded

⑤ Electrostatic protection measures should be taken when transporting, storing, and unpacking electrostatically sensitive products

⑥ The speed of injection, flow, transportation, winding and separation should be controlled. In the transportation of liquid, powder and other materials

Use a buffer in the pipeline

⑵ Prevent the human body from being charged

① Wear anti-static wristband

② Wear anti-static work clothes, clothes and hats

③ Wear anti-static shoes, socks and anklets

④ Wear anti-static gloves and finger cots

⑤ Physical activities unrelated to work (such as doing exercises, playing around, combing hair, eating, etc.) are strictly prohibited

⑥ Take an ion air bath

⑶ Material selection requirements

① Any materials that must or are likely to undergo contact separation should be considered to have their positions on the charged sequence list as close as possible

② The surface of the material should be smooth, flat, clean and pollution-free

③ Use static conductor materials and static dissipative materials

⑷ Process control measures

2. Reduce and remove static charges

⑴ Ground

① The floor and work tables, chairs, countertops, and table mats are properly grounded

② Human body grounding

③ Tools (soldering iron, soldering iron, stand, transport trolley, etc.) are grounded

④ Equipment and instrument grounding

⑤ Grounding of pipelines, transportation and transmission facilities, canning equipment, and storage facilities (equipment)

⑵ Humidification

① Use various appropriate humidifiers and spray devices

② Use a wet mop to mop the floor or sprinkle water to increase the temperature near the charged object or the environment

③ Use hygroscopic materials in full quantity with consent

⑶ Neutralization

According to the shape and characteristics of the place and charged objects, select an appropriate type of static remover to remove static charges on appliances, equipment, products, places, equipment and human bodies

⑷ Doping

① In AfricaA layer of substance is added to the surface of solid materials and appliances by spraying, coating, plating, applying, printing, pasting, etc. to increase surface conductivity and accelerate the leakage and release of charges

② Adding metal powder, conductive fiber, carbon black powder and other substances to non-conductive materials such as plastics, rubber, and anti-corrosion coatings

③ Mix conductive synthetic fibers or metal wires into cloth, carpets and other fabrics to improve the antistatic properties of the fabric

④ Add chemicals as antistatic additives to liquids that are prone to static electricity (such as gasoline, aviation kerosene, etc.) to improve the conductivity of the liquid material

3. Reduce static electricity hazard

⑴ Improve the anti-static ability of the product itself

① Adopt input and output protection circuit design for CMOS and other static-sensitive integrated circuits

② For static-sensitive electronic components and electronic equipment, adopt anti-static protection design (set up output and input protection circuits and networks, use isolation resistors, set up boundary protection rings, and use all non-sensitive components etc.)

③ Carry out electrostatic protection design for sensitive components (set up series current-limiting resistors, set up clamping discharge gaps, reduce transient energy density, avoid lead overlap and the formation of parasitic MOS capacitance, etc.)

⑵ Adopt electrostatic shielding and grounding design

① Adopt electrostatic shielding measures such as protective covers, covers, and sheets for sensitive parts and sensitive components to reduce the mechanical, induction and discharge hazards of static electricity

② The existence of isolated conductors should be avoided

③ Set up testing wells with shielding functions in liquid storage tanks and other facilities to ensure the safety of sampling and testing

⑶ Ensure the static electricity safety of equipment, facilities and workplaces

① Manipulate flammable and explosive liquids or powders so that the concentration of explosive compounds is below the limit concentration of combustion and explosion

② Keep various grounding facilities and systems in the workplace (lightning protection, fault protection, signal reference, earth electrode, static removal operations, etc.) correctly and effectively grounded

③ The electrostatic potential of each point in the operating area is within the range approved by the standard

④ Install partial dischargers, discharge brushes, etc. to continuously release electrostatic energy through corona discharge to keep the accumulated energy within a safe range

⑤ Strict electrostatic safety operating procedures

4. Strictly remove static electricity

⑴ Improve the responsibility system and rules and regulations for website construction

① Build a website to improve the electrostatic safety protection and management responsibilities of various personnel (technical and management personnel, operators), and have an inspection system in place

② Website building static electricity safety accident analysis system

③ Prepare specific and detailed anti-static operation procedures

④ Establish a regular testing system for the antistatic performance requirements of equipment, devices, equipment, utensils, tools, etc.

⑤ Analysis system for electrostatic damage mechanism of website building products

⑵ Training and Education

① Implement education on anti-static awareness, knowledge, technology and safety requirements for personnel at different levels and positions such as management, management, technical personnel, and operators

② Provide operational skills training and assessment for operators in different positions

⑶ Use of warning devices, signs, and symbols

① Warning marks or symbols should be placed on electrostatically sensitive products and on internal and external packaging

② Static-sensitive components and parts in devices and equipment should be marked or warned with warning symbols in accordance with the requirements of the standard

③ Special exception markings should be made for the static electricity removal workplace (work area)

④ Alarm devices should be installed on key control parts to remind people to handle them in time

⑷ Conduct testing according to standard regulations

① Tools, appliances, work clothes, shoes and socks, floors, tables, chairs and workbench mats that require anti-static performance should be tested regularly to ensure that they remain qualified

② Environmental parameters with clear index requirements (such as humidity, temperature, concentration, electrostatic potential, etc.) should be measured and monitored in accordance with regulations
