资料介绍

选用微米级聚酰胺1212(PA1212)对聚酰亚胺树脂结合剂金刚石砂轮进行改性.通过磨削测试,对改性前后树脂砂轮的耐用度、寿命以及磨削PCB加工用刀具的表面质量等进行了研究.结果表明:PCB刀具磨削用金刚石砂轮经过PA1212改性,耐用度提升59.5%,寿命提升71.2%;使用该砂轮加工的刀具刃口崩口概率降低,表面纹路更加均匀.

Polyimide resin grinding wheel was improved by adding micron sized polyamide 1212 (PA1212). The durability, the lifetime and the surface quality of printed circuit board (PCB) tools before and after improving the wheel were studied by grinding tests. Results show that after adding PA1212, the durability of the grinding wheel for PCB tools is improved by 59.5%, lifetime increased by 71.2%. It is also found that the probability of collapse at tool edge during grinding is greatly reduced and that the surface texture of the tool is more uniform.
