FR4 is a material made of glass fiber and epoxy resin, which has good insulation performance, mechanical strength and heat resistance. During the processing, the raw materials need to be processed and processed in a series of ways to understand the required shape and performance.

The first step in FR4 epoxy board processing is to prepare the raw materials. This includes steps such as mixing, stirring and etching of glass fiber and epoxy resin to ensure the quality and stability of the raw materials. During this process, parameters such as temperature, time and stirring speed need to be precisely controlled to ensure the uniformity and consistency of the material.

Next is the molding stage. At this stage, it is processed into the required shape and size. This usually involves a variety of processes such as hot press molding, cold press molding, and injection molding. During the molding process, it is necessary to ensure that parameters such as material density, thickness, and dimensional accuracy meet the requirements to ensure the performance and quality of the finished product.

In addition to molding, fr4 epoxy board processing also includes subsequent processing such as drilling, cutting, and grinding. These steps are essential to meet the needs of different applications. For example, drilling can provide channels for conducting circuits or installing electronic components; cutting can process large pieces of board into specific small pieces; grinding can improve the surface finish and flatness.

Finally, FR4 epoxy boards need to undergo a series of inspections and tests to ensure that their performance and quality meet the requirements. This includes electrical performance tests, mechanical performance tests, environmental adaptability tests, etc. Only FR4 epoxy boards that have been fully inspected and meet the requirements can be identified as qualified products and used in the manufacture of various electronic equipment and systems.
