Importance of PCB

It is an important electronic component that supports electronic components.

Printed circuit boards are not general end products and are slightly confusing in the definition of names.

For example, the motherboard used in personal computers is called a motherboard, but not directly called a circuit board. Although there are circuit boards in motherboards, they are not the same, so when evaluating the industry, the two are related, but cannot be said to be the same.

Another example: because there are integrated circuit parts loaded on the circuit board, so the news media called him IC board, but in essence he is not the same as the printed circuit board. What we usually refer to as a printed circuit board is a bare board - that is, a board with no components on it.

Common FR substrate materials.

FR-2 is made of multi-layer fiber paper impregnated with flame retardant phenolic resin. It has good resistance to stamping and is relatively low cost. It is often used for simple applications such as radios, calculators, or toys that do not require high dimensional stability and performance. FR-3 is also paper-based, but impregnated with an epoxy resin system.

With CEM-1, the core reinforcement is wood pulp paper and the fabric reinforcement is glass fiber cloth, both impregnated with epoxy resin. This material is easy to press and has good electrical and physical properties. CEM-1 has been used in a wide range of consumer and industrial electronics applications.

CEM-3 is different in that the core reinforcing material is glass fiber paper (non-woven glass cloth) impregnated with epoxy resin, and the fabric is reinforced with glass cloth and impregnated with epoxy resin. It is more costly than CEM-1, but is better suited for processing plated holes.CEM-3 has been used in early home computers, automobiles, and home entertainment products.

FR-4 is by far the most commonly used PCB substrate, made of glass cloth impregnated with epoxy resin or a hybrid epoxy resin. FR-4 substrates have excellent electrical, mechanical, and thermal properties, and are widely used in computers and peripherals, servers and storage networks, communications, aerospace, industrial controls, and automotive applications, making it the ideal substrate.
