In the ever-evolving landscape of electronics, miniaturization stands as one of the most prominent trends. From smartphones to medical devices, the demand for smaller, lighter, and more powerful gadgets continues to drive innovation. Among the myriad technologies enabling this trend, Chip Scale Packaging (CSP) substrates emerge as unsung heroes, facilitating the miniaturization process while maintaining functionality and reliability.


CSP substrate represents a pivotal advancement in electronic packaging, offering a compact solution that integrates semiconductor chips into a single package. This technology has significantly contributed to the reduction in the size of electronic devices, enabling the development of sleeker designs without compromising performance.


CSP Substrates


At its core, a CSP substrate serves as a foundation for mounting and interconnecting semiconductor chips within electronic devices. Unlike traditional packaging methods that leave considerable space around the chip, CSP substrates minimize the footprint by closely wrapping the chip with minimal extra ...
