System in Package (SiP) combines multiple dies and passive components within a compact package through heterogeneous packaging techniques, such as wafer-level packaging (WLP) and 3D stacking, enabling modular functionality and rapid prototyping. SoC fabrication demands high initial costs and complex process optimizations, while SiP manufacturing emphasizes flexible assembly and testing processes to accommodate diverse components and improve time-to-market.
Cost Considerations and Scalability
SoC designs generally offer lower unit costs at high volumes due to integrated components on a single chip, reducing manufacturing complexity and material expenses. SiP provides greater scalability and flexibility for varied applications by allowing customization of multiple heterogeneous dies in one package, but this often results in higher per-unit costs and increased assembly complexity. Cost-effectiveness depends on production scale, with SoC favoring large-scale deployment and SiP suitable for niche markets requiring rapid design iterations and integration of diverse technologies.
