- 【权利要求8】如权利要求7所述的电路板制作方法,其特征在于,所述陶瓷磨刷轮的磨刷精度为700~900目。
- 【权利要求9】如权利要求7所述的电路板制作方法,其特征在于,所述第二磨刷工序采用不织布或尼龙磨刷轮进行磨刷。
- 【权利要求10】如权利要求9所述的电路板制作方法,其特征在于,所述不织布或尼龙磨刷轮的磨刷精度为1100~1300目。
- 【权利要求11】一种电路板,其包括至少一个导孔,所述导孔中填充有填孔材料,填孔材料的表面和与导孔的导电层相连的铜层的表面位于同一平面。
- 【权利要求12】如权利要求11所述的电路板,其特征在于,所述填孔材料的表面和与导孔的导电层相连的铜层的表面位于同一平面是采用磨刷方法。
- 【权利要求13】如权利要求12所述的电路板,其特征在于,所述磨刷方法包括第一磨刷工序以及第二磨刷工序,所述第二磨刷工序的磨刷精度大于第一磨刷工序的磨刷精度。
- 【权利要求14】如权利要求13所述的电路板,其特征在于,所述第一磨刷工序采用陶瓷磨刷轮进行磨刷。
- 【权利要求15】如权利要求14所述的电路板,其特征在于,所述陶瓷磨刷轮的磨刷精度为700~900目。
- 【权利要求16】如权利要求14所述的电路板,其特征在于,所述第二磨刷工序采用不织布或尼龙磨刷轮进行磨刷。
- 【权利要求17】如权利要求16所述的电路板,其特征在于,所述不织布或尼龙磨刷轮的磨刷精度为1100~1300目。
