What material is used in CPU Package Substrates?

CPU packaging substrate is a vital part of modern electronic equipment, and the materials used play a vital role in its performance and stability. Typically, the CPU packaging substrate is made of materials such as fiberglass reinforced epoxy resin (FR4). FR4 is a common substrate material with good insulation properties, mechanical strength and heat resistance, and is suitable for most application scenarios.

However, as technology develops and application requirements continue to change, CPU packaging substrates are gradually using other materials to meet specific requirements. For example, for some applications that require high mechanical strength and high temperature resistance, such as automotive electronic systems or aerospace equipment, ceramic materials may be selected. Ceramic substrates have excellent high temperature resistance and mechanical strength and can work stably in extreme environments.

In addition, for some scenarios that have strict requirements on size and weight, polyimide materials may become the first choice. Polyimide substrates are lightweight, high-strength and have excellent electrical properties, making them suitable for high-density circuit design and miniaturization application scenarios.

In addition, some applications with special requirements may choose metal core substrates as the material of the CPU packaging substrate.

For small electronics such as mobile phones and wearable devices, the size of the CPU packaging substrate is often very delicate. Due to the high volume and weight requirements of these devices, the substrates are often very compact and small in size to accommodate the miniaturized design of the device. For example, the CPU packaging substrate of a smartphone may be only a few square centimeters in size, while the substrate size of wearable devices such as smart watches is even smaller.

In contrast, CPU packaging substrates used in large systems such as industrial equipment and telecommunications infrastructure require larger dimensions. These devices often need to process more data and complex tasks, so the substrate requires more space to accommodate more electronic components and complex circuit layouts. For example, a CPU packaging substrate for a factory automation control system may be several times larger than that of a smartphone, or even larger.

Not only that, but some specific applications may require very specific substrate dimensions. For example, some specially shaped substrates may be used in specifically shaped electronic devices or systems to maximize the use of available space. In some cases, the substrate may require custom design to meet specific size and performance requirements.
