摘要
钼铜钨铜材料的载体,由于孔隙率极低,在热沉制作和电子封装领域应用越来越广泛,但由于载体材料硬度高、厚度尺寸小等特点,传统机械加工方法无法对其进行有效加工。电火花线切割类非接触式特种加工方法为该类材料的顺利加工提供了解决方案。电火花线切割加工技术是一种通过在工具电极与工件之间施加电压,利用两者之间的脉冲性火花放电能量来蚀除工件表面多余的金属,从而使工件得到所需的形状、尺寸精度、表面质量的技术。分析钼铜钨铜材料特性,针对性寻求相应的线切割方案,设计相关加工实验,探究整体工艺方案和工艺参数,加工出符合技术要求的产品。这种加工方式为后续开展钼铜钨铜载体更高效、更高精度的加工提供了宝贵的参考。
The carrier of molybdenum-copper and tungsten-copper material was more and more widely used in the field of heat sink production and electronic packaging because of its extremely low porosity.However,due to the characteristics of high hardness and thin thickness of the carrier material,the traditional mechanical processing method could not effectively process it.Wire Electrical Discharge Machining(WEDM),a non-contact special processing method,provided a solution for the smooth processing of this material.WEDM was a kind of technology,which provided voltage between the tool electrode and the workpiece,and used the pulse spark discharge energy between the two to remove the excess metal on the workpiece surface,so that the workpiece got the required shape,size precision,surface quality.We analyzed the characteristics of molybdenum-copper and tungsten-copper materials,found out the corresponding WEDM scheme,and designed relevant processing experiments,so as to explore the overall process scheme and process parameters,and process the products that met the technical requirements.This processing method provided a valuable reference for the subsequent development of more efficient and higher precision processing of molybdenum-copper and tungsten-copper carriers.
