Supply non-woven brush roller, scouring pad roller, 3M scouring pad polishing roller

The non-woven brush roller adopts the first two production structures, namely, radial (Flaptype) and disc (Disktype). Due to the different combinations of materials, density and processing technology, it can meet the different needs of various customers. Non-woven brush rollers are divided into silicon carbide (SIC) abrasives, alumina (AO) abrasives and pure non-wovens according to the different abrasives contained in non-wovens. Whether it is silicon carbide (SIC) or alumina (AO) abrasives, their particle size distribution ranges are: 60#, 80#, 100#, 120#, 150#, 180#, 240#, 320#, 400#, 500# , 600#, 800#, 1000#, 1200#, 1500#. The non-woven fabric brush roller is characterized by fine grinding and uniform roughness of the processed surface, which can significantly improve the adhesion of the photosensitive film and the green oil film. It is especially suitable for line width/line spacing (L/S) ≤ 100um (u003d 4mil) ), the manufacture of PCB with copper foil thickness ≤35um. It has excellent performance in the fields of burr removal after drilling, photosensitive film pretreatment and green oil (anti-oxidation) pretreatment. Especially in the pretreatment process of green oil (anti-oxidation), the non-woven brush roller has a strong ability to remove the hard burrs and pollution on the board surface. The disadvantages are that the surface of the circuit board will be obvious when the surface defect of the non-woven brush roller due to some reasons is encountered. The traces that cannot be brushed often cause the entire brush roller to be scrapped. Secondly, if the circulating water treatment of the brushing machine is not good, and the water pressure for high-pressure cleaning is not high, the abrasives ground from the non-woven fabric will block the nozzles, and the high-pressure water washing will cause the circuit board to block the holes and cause the circuit board to be behind. Go to the process to be scrapped. But its fine grinding has proven to increase the yield or reduce short circuit, open circuit and electrical test test NG 10%-15% or more. In addition, the service life of the non-woven brush roller is shorter than that of the nylon brush roller, so the grinding cost is high, but it is worthwhile to calculate the improvement of the product yield.
