Ultra-fine diameter superhard discharge machining electrode for semiconductor molds
Tungsten carbide electrode with a minimum diameter of φ0.01. For precision drilling of fine holes in mold processing.
In the semiconductor industry, high-precision micro-machining is required for mold processing. In particular, for molds that are essential for semiconductor manufacturing, the ability to process fine holes with high precision significantly affects product quality and yield. Conventional electrodes have limitations in terms of thinness and durability, leading to challenges in machining accuracy and efficiency. Sanwa Creation's ultra-small diameter carbide discharge machining electrodes address these issues. 【Application Scenarios】 - Micro hole processing for semiconductor molds - Electrical discharge machining of precision parts - Mold processing requiring high-precision drilling 【Benefits of Implementation】 - Achievement of high-precision micro hole processing - Improvement of mold lifespan - Reduction of processing time - Increase in yield

Applications/Examples of results
Compared to copper and copper alloys commonly used as electrode materials for conventional electrical discharge machining, cemented carbide does not have good electrical conductivity. However, leveraging the extremely high hardness of cemented carbide (around HRA90), we have developed electrical discharge machining electrodes for ultra-small diameter holes to meet the demand for drilling straighter and finer holes.
