What are the advantages of cleaning cotton swabs ?

The clean cotton swabs are also called dust-free wipe sticks, dust-free cotton swabs, which are produced and processed in the cleaner workshop with high-definition cleanliness. The biggest difference between clean cotton swabs and general cotton swabs is as follows: material, function and advantage.

Material: the dust-free cleaning cotton swabs / wipe rods are divided into sponge head and cloth head. They are treated without dust and packed in a clean room. Because the wiping consumables used in high-level dust-free environment must reach more than 100, only dust-free cotton swabs can meet the requirements. They are mainly used for HDD, PCB, FPD, lens, semiconductor and other work to wipe the attachment, dust dust wait.

Advantages:
a: Knitted nylon (super wear-resistant)
b: Knitting superfine fiber (wipe fine dust, wear resistance is general)
c: Woven microfiber (professional for fiber wipe)
d: Knitted polyester (the fabric surface is longitudinal, with deep gap, which can accommodate more dirt)
E: non woven cloth head (low grade, but relatively small processing difficulty and low price)
The above dust-free cotton swabs can be used in 100 grade clean room, suitable for electronic use. Sponge head cotton swabs can have the following two types according to the density and chip removal condition of sponge:
1: Open hole Pu sponge, 100ppi (PPI -- port per inch, refers to the number of holes per inch, the more the number, the more delicate the sponge, it is also less simple to remove the debris). The sponge has lower density and is easy to remove debris, but the water absorption rate is fast, and suitable for medical use;
2: The open Pu sponge, 400-500ppi, is more dense than that of 100ppi sponge, and it is more difficult to remove dust, and has high dust-free grade, and is suitable for electronic use.
