Glass Epoxy Substrate is a type of printed circuit board.
A printed circuit board is an insulator board with only wiring on its surface or inside, and is a basic component used to build electronic circuits by mounting electronic components on the board. There are two types of printed circuit boards: rigid boards made of inflexible rigid materials and flexible boards made of flexible thin materials.
Glass Epoxy Substrate is one type of rigid substrate. It is made of glass epoxy material in which glass fibers are layered in a cloth-like shape and impregnated with epoxy resin.
The most common printed circuit board is Glass Epoxy Substrate. With excellent electrical and mechanical properties, most printed circuit boards used as double-sided or multilayer substrates are Glass Epoxy Substrate.
Glass epoxy substrates have excellent durability, thermal insulation, flame retardance, and low conductivity. Therefore, they can be used in circuits that require high-frequency operation and high reliability, such as PCs, consumer electronics, OA equipment, IC cards, digital cameras, and motherboards.
Printed circuit boards are made from copper clad laminates (Copper Clad Laminate) as a base, copper foil to form circuit patterns, and ink to protect the board surface (solder resist ink).
Glass Epoxy Substrate is composed of glass epoxy material, which is epoxy resin added to glass fiber cloth as a copper clad laminate.
There are several types of printed circuit boards, such as Paper Phenolic Substrate, Paper Epoxy Substrate, Glass Composite Substrate, and Glass Epoxy Substrate, depending on the base material that makes up the copper-clad laminate. FR (Flame Retardant) grade is used to classify the heat resistance and flame resistance of printed circuit boards.
Common Glass Epoxy Substrate is classified as FR-4 and is called FR-4 Substrate. FR-4 Substrate has advantages such as good high-frequency and electrical characteristics, durability, moisture absorption, flame retardancy, and low dielectric constant, but also has disadvantages such as high moisture absorption and poor processability.
Furthermore, there is a type of Glass Epoxy Substrate classified as FR-5, which has higher heat resistance than FR-4, and FR-5 substrates can be applied to automotive applications that require high heat resistance.
Rigid substrates such as Glass Epoxy Substrate are made of paper or glass cloth, and the base resin can be epoxy resin or phenolic resin. The types of structures for each circuit layer of Glass Epoxy Substrate can be divided into single-sided substrates, double-sided substrates, and multilayered substrates.
In a single-sided substrate, the wiring pattern is formed on only one side and electronic components are mounted. In the case of Glass Epoxy Substrate, the structure is composed of solder resist, copper foil, and glass cloth in this order from the top.
In a double-sided substrate, wiring patterns are formed on both sides. The structure from the top is solder resist, copper foil, glass cloth, copper foil, and solder resist. The glass cloth, the base material, is located in the center, and the structure of a single-sided substrate is on both sides. In the case of a double-sided substrate, holes such as vias and through holes can be made to allow current to flow between layers and lead components to be inserted.
A multilayer board is a board with four or more layers of insulators and patterns. Basically, it has the same structure as a double-sided board. Copper foil, glass cloth, and copper foil are in the center, and as layers are stacked, more copper foil is added and covered with solder resist.
Since printed circuit boards have different moisture absorption and heat resistance temperatures depending on their materials, choosing an inexpensive printed circuit board to reduce cost may not be suitable for your application. Using a PCB that is not suitable for the application may result in unstable operation of electronic equipment or even combustion accidents.
It is important to compare the service life and heat resistance temperatures of materials and select the right material for the intended use. In the case of precision printed circuit boards, handling and storage methods during manufacturing and surface mounting should also be checked.
