I. Product Introduction
1. It can support the grinding of all printed circuit boards, especially for the whole surface treatment of the dry film laminates used in printing, it is widely praised.
2. The brush wheel is developed for the process of filling holes, overflowing glue and removing holes. EC radiation brush selected high shear force of grinding ore, and special glue will be fixed on the ore firmly non-woven fabric fiber, to strengthen the effect.
3. Non-resin immersion, so has superior flexibility, with different surface height fluctuations suitable for a variety of cleaning and micro-grinding purposes. The excellent results are obtained by removing the oxide layer, refining the lines on the surface, nickel plating on the gold finger and research treatment before gold plating.
4. As a general-purpose brush wheel, stable quality, good durability.
5. Inner tube type: BK (bakelite tube)
