Anti-static ballpoint pens are EPA area materials
Anti-static ballpoint pens are EPA zone materials. The criterion is whether static-sensitive items are present in the area. As long as static-sensitive items may appear and the static-sensitive items are not in an electrostatic shielding state, it should be defined as an anti-static area. Otherwise, it can be defined as non-anti-static. district. The boundary range of the anti-static area is determined jointly by the regional leader and the ESD responsible person. All equipment, instruments, test environment equipment, tools, and human bodies in the EPA area should be safely and reliably grounded to ensure that electrostatically sensitive items, staff, and all other conductors are in an equipotential state, so that electrostatically sensitive items are protected from ESD damage.
Surfaces where static-sensitive products are directly placed should be made of static-dissipative materials and reliably grounded. Its surface resistance and grounding resistance should be maintained at 1.0*104Ω≤R<1.0*109Ω.
Common static sources in the EPA, such as anti-static stationery, pens, scanner guns, tape holders, monitors, scissors, alcohol bottles, keyboards, mice, folders, card holders, power strips, trash cans, etc., should be subject to effective static control. Requirements Prioritize the use of anti-static materials, and alternatively use anti-static tape to wrap or place them at a distance of more than 30cm from the operating area of electrostatic-sensitive products and place them in a fixed position. High-static power sources such as plastic trash cans are required to be at least 1m away from the operating area of electrostatic-sensitive products. The use of aluminum foil tape for wrapping is prohibited.
