Temperature management is of paramount importance when it comes to ensuring the reliability of electronic devices. Various materials exhibit distinct thermal conductivity properties, which profoundly influence temperature distribution within the device. Rigid substrates typically boast high thermal conductivity, facilitating heat dissipation and effective temperature control. Consequently, material selection must diligently factor in the imperative of temperature management to uphold device stability and reliability.

Sustainability considerations: highlighting the impact of material selection on sustainability

In today’s electronics world, sustainability is increasingly valued. Material selection has a significant impact on sustainability. Selecting recyclable or reusable materials, reducing waste generation, and adopting environmentally friendly manufacturing processes are crucial to protecting the environment and resources. Rigid substrates often present sustainability challenges, while flexible substrates and high-performance polymers offer additional sustainability advantages. Therefore, sustainability factors must be actively considered when selecting materials to meet environmental protection requirements and ensure the sustainable development of electronic products.
