Challenge 2: Signal Integrity and Electromagnetic Interference (EMI)

The components within the SiP module can lead to signal interference and degradation, affecting the performance of smart cockpit features. Additionally, Electromagnetic Interference (EMI) may arise due to the compact layout, potentially impacting the module's stability. 

Solution: EMI Shielding and Signal Routing Techniques

Engineers use EMI shielding materials and advanced signal routing techniques to ensure optimal signal integrity and minimize EMI. Considering the layout carefully and using ground planes and signal traces helps reduce signal interference and provides smooth data exchange between different components.

Challenge 3: Cost Optimization

While SiP modules offer numerous benefits, their complex design and manufacturing can result in higher production costs. Striking a balance between the advantages of SiP technology and cost-effectiveness becomes a crucial concern while conducting a SiP module project.

Solution: Design Optimization and Material Selection

To address cost optimization, manufacturers streamline the SiP module's design and carefully select cost-effective yet reliable materials. Collaborating with semiconductor suppliers and optimizing the supply chain also reduces production costs.

USI collaborates closely with automotive SoC solution providers to advance smart cockpit systems. By leveraging the solutions above, USI has reduced automotive compute module size while ensuring high DDR operational speed. The modular design minimizes mainboard footprint, enhancing computational performance and smart cockpit system quality and efficiency.

Embracing automotive compute modules streamlines carmakers' focus on mainboard development, saving on research and development costs. This approach reduces mainboard costs for manufacturers and facilitates high-density PCB designs within smaller module areas.

Our approach includes advanced underfill, BGA (Ball Grid Array) mounting, embedded passive components, and high-density SMT (Surface Mount Technology) in module development. Modules feature critical control components like System-on-Chips (SoCs), dynamic random-access memory (DDR), and power management integrated circuits (PMICs), operating independently of the mainboard.
