Start of Mass Production for Sumilight® CSL-Z7304 High-Speed Sealing Cover Tape

Sumitomo Bakelite Co., Ltd. (headquartered in Shinagawa, Tokyo; President: Shinichi Kajiya) has officially commenced mass production of their high-speed sealing cover tape, Sumilight® CSL-Z7304. This innovative tape has been engineered to achieve adequate peel strength even with significantly reduced sealing times, catering to the small electronic components that require greater efficiency in production.

Development Background

The rapid advancement and increasing performance of smart devices have led to miniaturization in the electronic components used. As part of this trend, manufacturers are facing the growing demand for more efficient production processes. This includes the need for cover tapes that can accommodate ultraminiature components and that also offer high-speed sealing capabilities for encapsulating items into carrier tapes within shorter timeframes.

Features of Sumilight® CSL-Z7304

The new Sumilight® CSL-Z7304 features an optimized sealant layer design that ensures sufficient peel strength is attained even with short adhesive times. This enhancement not only streamlines customers' production processes but also boosts overall productivity. The tape is constructed from robust materials, meeting the JIS standard (C0806-3) with a break strength requirement of 10N or more, making it less prone to tearing. Moreover, the product possesses excellent transparency, allowing for easy identification of packaged electronic components or semiconductors, and minimizing any hindrance during camera inspection processes.
