Diamond Wire Cutting Systems for Package Substrate Slicing & Precision Component Cutting
Chip carrier and package material precision cutting systems can make the difference between yield and scrap in high-volume semiconductor packaging. They provide a reliable processing solution by cutting brittle, multi-layer packaging substrates and lead frames with ultra-high accuracy. Especially for packaging manufacturers, many factors have to be kept in mind in order to be able to guarantee the dimensional accuracy and structural integrity of the components.
In order to process multi-layer packaging materials with complex structures and high hardness, a stable cutting process must be achieved with minimal kerf loss and sub-surface damage. To ensure that the increasing precision requirements of advanced packaging do not lead to component defects or yield loss, the performance of the cutting systems used must be guaranteed at all times. In order to be able to guarantee this performance, diamond wire cutting systems must be tested in accordance with semiconductor industry standards at accredited testing laboratories.
Industry-standard certified cutting systems are subject to defined guidelines with regard to process modifications. ewirexon uses a special production and process optimization process to help you ensure that the high qualitative requirements of advanced packaging are met.
ewirexon diamond wire cutting systems for package material processing are characterized by an optimum price/performance ratio and are particularly suitable for precision cutting of chip carriers, lead frames and multi-layer packaging substrates. The systems generate ultra-high cutting accuracy with minimal kerf loss in limited production space. With rigid machine frames that can meet the strict precision requirements of advanced packaging, ewirexon offers an efficient and reliable option for fabs that handle both R&D prototyping and high-volume production at the same time. Thanks to a wide range of performance and customized process parameters, manufacturers of semiconductor packaging can reduce their component diversity with ewirexon’s Package Material Cutting solution.
