Diamond Wire Cutting Systems for High-Precision Component Slicing
Microelectronic components and precision substrates experience extreme stress during high-speed slicing. To ensure ultra-high precision, minimal sub-surface damage and avoid chip cracking that lead to performance loss, device manufacturers require stable cutting dynamics and precise process control. This is the only way to achieve reliable, high-yield production of microelectronic components.
Microelectronic processing involves high material and production costs. Around 30% of total manufacturing cost is attributed to inefficient cutting, excessive kerf loss and low yield. The application-specific selection of ewirexon diamond wire cutting systems can therefore make a decisive contribution to reducing production costs.
High-precision wire saws are used to slice hard, brittle components into thin wafers with stable tension control. Their operating parameters typically lie in the optimal process window, which is characterized by consistent tension, low vibration and narrow cutting width.
The new Microelectronic Component Precision Cutting diamond wire saws from ewirexon are specially developed for high-precision slicing of microelectronic components and brittle-hard substrates, where ultra-high cutting accuracy and minimal material loss are required. The new Microelectronics Series achieves significantly higher cutting precision and material yield than competitor products in this application area. The use of our cutting systems enables savings in production costs for microelectronic manufacturers. Another positive side effect is the reduction of material waste and surface damage.
