የ COF ቁሳቁስ

The COF scheme mainly uses polyimide (PI film) mixture materials, with a thickness of only 50-100um, and line width and line spacing below 20um. COF packaging is produced using automated roll-to-roll equipment, which is continuously heated to 400 degrees Celsius during the production process. Since the COF roll-to-roll production process requires heating, and the thermal expansion coefficient of PI film is 16um/m/C, compared to the chip's 2.49um/m/C, the thermal stability is poor, so equipment accuracy and process requirements are required Very high.

FPC: ንዑስ እና ሽፋን ቁሳቁስ

የ FPC አጠቃቀም በአጠቃላይ ተጣጣፊ የመዳብ ፎይል ንጣፍ (ኤፍ.ሲ.ሲ.ኤል) ፣ የሽፋን ፊልም (Coverlayer) ፣ የማጠናከሪያ ሰሌዳ እና ፀረ-የማይንቀሳቀስ ሽፋን እና ሌሎች ቁሳቁሶች እንዲሰሩ ለማድረግ ከመዳብ ፎይል እና ከፒአይ ፊልም ቁሳቁሶች የተሠራ ነው ፡፡

The thickness of PI film can be divided into 0.5 mil, 1 mil, 2 mil, 3 mil and thick film (even products above 10 mil). Advanced or high-end soft boards need to be thinner (0.3 mil) and have more stable dimensional stability. PI film. The general cover film mainly uses PI film with a thickness of 0.5 mil, while the thicker PI film is mainly used for reinforcing plates and other purposes.

In recent years, the increasing demand for applications such as smart phones, tablet computers, liquid crystal displays, and LED backlight modules has driven the demand for PI films. As the proportion of mid-to-high-end mobile phone market shipments has increased year by year, coupled with the surge in demand for smartphones in emerging countries and regions such as Southeast Asia, FPC demand is expected to maintain considerable growth in the next 3-5 years

Semiconductor packaging

Modern electronic packaging technology requires a combination of interconnection technology, power, cooling technology, and device passivation protection technology to ensure that the device has the best performance and reliability.

Polyimide meets the requirements of high purity, high heat resistance, high mechanical properties, high insulation properties, high frequency stability, low dielectric constant and dielectric loss, low moisture absorption, and low internal stress to a large extent. Requirements, low thermal expansion coefficient and low molding process temperature requirements have become the core materials of advanced packaging.
