What are the requirements for the selection of PCB substrate materials? Today we will explain to you in detail:
1. Meet the characteristics of the circuit and the requirements of the printed board environment
The selection of substrates must first consider the characteristics of the circuit and the requirements of the environment in which the printed board is used. The working characteristics of the circuit on the printed board are closely related to the performance of the base material. When selecting the base material, the matching between the performance of the base material and the circuit must be considered. Otherwise, no matter how good the quality of printed board processing is, it is difficult to guarantee good working performance of the circuit.
The use environment of printed boards is a factor that must be considered in the selection of substrates. The performance degradation of printed boards under the use of environmental conditions cannot affect the quality of electronic products.
2. Meet the reliability requirements of the product
Product reliability is the ability of a product, device or system to perform specified functions under specified conditions and within a specified period of time. Printed boards are the basic components of electronic complete products, and their reliability requirements should be higher than those of complete products. The higher the requirements for the reliability of printed boards, the more stable and reliable the required substrate performance is. .
3. Consider the manufacturability requirements of the product
Considering the manufacturability of the product should include the manufacturability of the manufacture and installation of the printed board. The performance of the substrate should be able to meet the manufacturing and installation process requirements of the printed board.
4. Consider cost requirements
The principle of the lowest cost must be considered in the design of any product, and the same is true for the selection of substrates for printed boards. On the premise of meeting performance and use requirements, try to consider low cost. There are many types of substrates, and the cost varies greatly. When selecting, it is necessary to optimize the cost performance of the substrate and choose the substrate with the best cost performance.
5. Environmental requirements
Considering environmental protection is an inevitable trend in the development of technology in the world today. In the process of product design, it should be considered that the product has the lowest impact on the environment throughout its life cycle. Therefore, when selecting substrates, renewable, recycled or environmentally friendly materials should be used to the greatest extent. Material.
