Advanced wafer processing, chip packaging, lithography inspection, and precision semiconductor workstations have stringent requirements for wiping, dust removal, and static control; ordinary lint-free wipes cannot meet the wiping standards of high-end production lines. Many semiconductor and optoelectronics companies have adopted Li Jieqing anti-static lint-free wipes as standard consumables for their production lines. Below, we break down the five key advantages of these lint-free wipes to understand how they safeguard the quality of precision semiconductor manufacturing.
01
Class 1,000 Cleanroom Weaving Process for Strict Control of Lint and Fiber Shedding
In Class 1,000 cleanroom wiping stations, fibers and microparticles shed from the cloth can adhere to chip leads and wafer surfaces, causing short circuits and cosmetic defects.
1. High-Temperature Setting Process to Lock Fibers in Place
Woven from polyester filaments and set through high-temperature pressing, the fibers are firmly locked in place. The cut edges undergo ultrasonic sealing, significantly reducing lint and debris shedding.
2. Dust-Free Washing and Purification
Finished products undergo multiple rinses with ultrapure water, followed by purification and drying, to remove weaving oils, dust, and sizing residues, resulting in low ionic residue on the cloth surface.
3. Purified, Individually Packaged
After washing and drying, the cloths are individually packaged and sealed in a cleanroom. They can be used directly in cleanrooms upon unboxing, without the need for secondary cleaning.
Ordinary household wipes and economy-grade dust-free cloths lack sealed edges and are not washed with ultra-pure water. They generate significant debris during wiping and are suitable only for cleaning standard enclosures; they must not be used on the precision surfaces of chips or wafers.
02
Stable ESD Protection
Memory chips, bare PCBs, and wafer probe stations are all electrostatic-sensitive components. Wiping and friction generate static electricity, which can easily cause hidden breakdowns. Li Jieqing anti-static lint-free wipes are embedded with long-lasting conductive fibers, with a surface resistance ranging from 10⁶ to 10⁹ Ω. They do not easily accumulate static electricity during friction, and wiping operations pose no risk of electrostatic discharge, meeting semiconductor ESD control standards.
03
High Liquid Absorption and Retention Capability for Efficient Removal of IPA and Cleaning Agent Residues
Production line wiping often involves the use of isopropyl alcohol and high-purity cleaning agents. Li Jieqing’s anti-static lint-free wipes feature a dense filament structure that offers rapid liquid absorption and strong retention capabilities, minimizing dripping and preventing secondary liquid runoff that could contaminate wafers during wiping. The wipes are soft with low friction, ensuring they do not scratch plated or polished surfaces during use.
04
Low ionic leaching, preventing corrosion and discoloration of metal leads
Through deionized water washing and quality control, the content of leachable ions such as sodium, potassium, and calcium is kept low. Long-term wiping of gold- and silver-plated leads reduces delayed oxidation and corrosion issues, making it suitable for chip testing and packaging cleaning processes.
05
Multiple specifications available to meet wiping needs across the entire production line
Offers multiple mainstream grammages and sizes, including 1009, 3109C, and 4009, with options for laser-sealed or ultrasonic-sealed edges. Suitable for wiping at photolithography stations, cleaning wafer cassettes, wiping fixtures, and wiping optical lenses—a single set of consumables accommodates a wide range of semiconductor wiping scenarios.
