What is Package Substrate Prepreg?

Package substrate prepreg stands as a prominent material in the manufacturing of package substrates. The term “prepreg” is a contraction of “pre-impregnated,” denoting a substrate that undergoes resin impregnation as a preliminary step. Typically, it involves a layer of fiberglass cloth coated with resin that has not undergone full curing. The unique characteristics of this material designate it as a crucial element in the production of packaging substrates.

The role of Prepreg is to act as an interlayer insulating material for the packaging substrate. It is used in constructing multi-layer boards to ensure the reliability and stability of circuits by providing insulation between conductive layers. During the manufacturing process, Prepreg plays a key role in connecting the conductive layers and curing them into a strong material.

Package Substrate Prepreg has a wide range of applications in electronics manufacturing, particularly in printed circuit board (PCB) and packaging technology. In PCB manufacturing, Prepreg is used to build multilayer boards to ensure that electrical signals between different layers do not interfere with each other. Its high degree of insulation and heat resistance make it a common and critical material in electronic devices.

In packaging technology, Prepreg is used to prepare packaging substrates, such as Ball Grid Array (BGA) packaging. By stacking Prepregs together and allowing them to cure during a heat treatment process, a strong substrate is formed that supports chips and other packaged components. This application makes Prepreg play a key role in packaging and connections in modern electronic devices.

Overall, Package Substrate Prepreg, as an advanced electronic material, plays an indispensable role in electronic manufacturing due to its unique structure and characteristics.

Technology for preparing Package Substrate Prepreg

In the preparation process of Package Substrate Prepreg, key technical steps include resin impregnation and heat treatment. These two steps play a vital role in ensuring final product quality and performance.

The principle of resin impregnation

Resin impregnation is one of the core processes in Package Substrate Prepreg preparation. In this step, pre-cut substrates are combined with resin to create a uniformly saturated composite. The key to this process is to ensure that the resin is evenly distributed in the fiber gaps of the substrate to provide optimal electrical properties and mechanical strength.

Key steps in the preparation process

Substrate Preparation: Before impregnation begins, the substrate needs to be properly treated and pre-treated to ensure that its surface is clean, uniform, and able to effectively receive the resin.

Resin Selection: Selecting the appropriate type and properties of resin is key to successful impregnation. Properties such as resin viscosity, flow, and interaction with the substrate need to be carefully considered.

Impregnation process control: Real-time monitoring of parameters during the impregnation process, such as temperature, pressure and resin concentration, to ensure uniform impregnation and avoid over- or under-impregnation.

Application of Package Substrate Prepreg in Electronic Manufacturing

In the field of electronic manufacturing, Package Substrate Prepreg plays a vital role, and its key role profoundly affects the performance and reliability of the packaging substrate.

Prepreg’s criticality stems from its bonding role in the package substrate stackup. This special prepreg contains resin and fibers. During heat treatment, the resin saturates the fibers and hardens, forming a strong inter-layer connection. This laminated structure provides a high degree of mechanical strength and electrical performance, ensuring that electronic equipment can operate reliably in complex working environments.
