采用光固化树脂作为结合剂制作金刚石锯片是近年来快速制造领域里的一个新型制造工艺,针对各种材料进行的切割试验也验证该项技术的可行性和实用性。在使用过程中发现锯片的导电性是一个非常重要的性能要求。对高分子材料的导电性研究进行比较,分析几种不同的实现光固化树脂导电性的途径,找出适合光固化树脂结合剂锯片的有效方法。通过采用镀铜金刚石作为磨料并适量添加导电铜粉,利用试验手段调整配方,最终达到了在光固化树脂结合剂超薄锯片的制造中实现具有导电性的目的。
Recently the application of diamond dicing blade bonded with photopolymer resin has been developed. Having electrical conductivity is necessary for most of blades used in dicing saw. The electrical conductivity ofphotopolymer resin bond dicing blade is studied. The theoretic research is studied with the investigation and analysis of other's achievements for electrical conductivity in polymer or resin, and the experiments are done to verify the validity of the measures for making conductive photopolymer resin bond dicing blade. The copper coated diamond added with appropriate amount of copper powder is introduced to fulfill the electrical conductivity of the dicing blade. The experimental results are perfect, which demonstrates the theoretic research and experimental measures are of high reliability.
