一种用于高可靠性楔焊劈刀的碳化钨材料，其成分以重量百分比计，由以下组分组成：WC 55‑74.5%、TiC 20‑35%、Co 2‑15%、Ni 2‑15%、Cr2C3 0.15‑1%、VC 0.15‑1%、Mo 0.5‑10%、K 0.5‑15%，所述K为钽的碳化物、铪的碳化物、铌的碳化物、铼的碳化物、碳化钽铌固溶体、碳化钨钛固溶体中的至少一种；其生产方法是采用变径内孔近净模压技术；该生产方法进一步突破了碳化钨材料的键合使用范围，大幅提升碳化钨材料的键合使用寿命，同时，实现了台阶式内孔碳化钨楔焊劈刀的一体成形，大大减少了劈刀加工工序，大幅降低碳化钨楔焊劈刀生产成本。
Description
技术领域
本发明属于集成电路工具材料领域，具体涉及一种用于高可靠性楔焊劈刀的碳化钨材料及其生产方法。
背景技术
电子装备（机载、舰载、星载等雷达和通讯系统）不断向微型化、轻量化、高频化、多功能、高可靠和低成本的方向发展，对集成电路芯片级组装和互连技术提出了更高要求，即对芯片级引线键合提出了极大挑战，而楔形劈刀成为高密度、小焊点、细间距和多腔深腔楔焊键合的关键工具。尤其是手动型楔焊键合过程中，稳定的引线送丝、引线出丝、引线断丝以及操作手法对键合可靠性影响显著，这也对楔焊劈刀的自身结构提出了新的要求，例如，典型的过渡垂直送丝引线孔结构，其包括喇叭入口、粗引线孔、过渡引线孔、细引线孔等部分，典型过渡引线孔是由直径0.4mm内孔过渡到直径0.15mm内孔，即垂直引线孔出口直径为0.15mm，其引线出丝的稳定性显著提升。
目前，采用激光加工、电加工等方式可以实现过渡性变径内孔的加工，但其加工难度大、加工成本高昂，因此，开发低成本制造技术势在必行。
发明内容
鉴于现有技术存在的问题，本发明针对熔点相对较低的碳化钨材料，通过材料成分设计与调控，开发出变径内孔近净模压技术，不仅拓宽碳化钨劈刀的键合适用性，而且大幅降低碳化钨劈刀制造成本。由此，本发明提出一种用于高可靠性楔焊劈刀的碳化钨材料及其生产方法，为进一步提高楔形劈刀的结构设计和使用性能，本发明提供一种用于高可靠性楔焊劈刀的碳化钨材料及其生产方法。
本发明的第一方面，是提供一种用于高可靠性楔焊劈刀的碳化钨材料，其成分以重量百分比计，由以下组分组成：WC 55-74.5%、TiC 20-35%、Co 2-15%、Ni 2-15%、Cr2C30.15-1%、VC 0.15-1%、Mo 0.5-10%、K 0.5-15%，所述K为钽的碳化物、铪的碳化物、铌的碳化物、铼的碳化物、碳化钽铌固溶体、碳化钨钛固溶体中的至少一种。
优选方案，本发明的碳化钨材料，其成分以重量百分比计，由以下组分组成：WC55-65%、TiC 25-30%、Co 2-6%、Ni 2-6%、Cr2C3 0.15-0.75%、VC 0.15-0.75%、Mo 0.5-7.5%、K 1.5-7.5%，所述K为（Ta、Nb）C、（W、TiC）C。
优选地，碳化钨材料硬度为80.5-95.5HRA、抗弯强度>1300MPa；所述碳化钨材料制备成的手动型楔焊劈刀的键合次数大于10万次。
