Introduction to IC chip scale packaging

Chip-scale packaging is a method of processing chips and packaging materials together to form chip packaging, including gluing, bonding, hot pressing, hot melting, welding and other processing technologies. It has the characteristics of low cost, high reliability and fast packaging speed. Chip-scale packaging is widely used in chip manufacturing due to its high performance, low cost and ease of reliability testing.

Selection of chip operating temperature

Chip operating temperature is one of the important factors that determine the quality of chip-level packaging. Excessive chip operating temperature will cause chip aging to accelerate, thus affecting the performance and life of the chip. At the same time, if the chip operating temperature is too low, the electrical performance of the chip will deteriorate, thereby reducing the reliability of the chip.

Generally speaking, the selection of chip operating temperature should be comprehensively considered based on factors such as chip materials, manufacturing processes, and application scenarios. Generally, the operating temperature of chip-scale packaging should be within the chip temperature range.

The following aspects need to be considered during the specific selection process:

1. Determine the nominal temperature of the chip and the temperature range of the chip.

2. Determine the temperature range of the chip-scale package, which is generally slightly larger than the temperature range of the chip.

3. Consider the peripheral equipment such as power supply and heat dissipation required for the chip’s operating temperature to ensure the normal operation of the chip.

4. If the chip works in extreme environments, such as high temperature, low temperature, etc., the package needs to be specially designed to ensure the normal operation of the chip.

In the actual application process, the working temperature of the chip will also be affected by other factors, such as application scenarios, working conditions, usage environment, etc. Therefore, the operating temperature selection of chip-scale packaging must take into account various factors to ensure the normal operation and long-term stability of the chip.

Summarize

Chip-scale packaging is an advanced technology, and the choice of chip operating temperature is one of the important factors affecting packaging quality. When selecting the chip operating temperature, factors such as chip materials, manufacturing processes, application scenarios, and working conditions must be comprehensively considered to ensure the normal operation and long-term stability of the chip.
