How to choose high frequency circuit board?

High frequency circuit board is mainly used for the accessories used in precision instruments. In the process of production and manufacturing, it has high requirements on its physical properties, precision and technical parameters. It can not only achieve high-speed signal with high requirements, but also improve the operation speed of relevant transmission devices. At the same time, different materials for circuit board are also required It will affect the performance of the product. So, how should people choose economical high frequency circuit board?

1、 Manufacturability. In order to make the high-frequency circuit board give full play to its performance, it is necessary to test the bonding performance and temperature performance of the high-frequency circuit board for many times in the manufacturing process, as well as its heat resistance, mechanical toughness and fire rating and other factors.

2. Various properties matching with products. When selecting high-frequency circuit boards, we should choose the products with low loss, low dispersion and stable Dk / DF parameters, and select the high-frequency circuit boards with small coefficient of variation with frequency and environment and small tolerance of material thickness and glue content, so as to better play its performance characteristics when using other products.

Third, the timely availability of materials. As high-frequency circuit board involves higher requirements of production technology, it has a longer production and procurement cycle. If people need to purchase, they should communicate with the manufacturer in advance and prepare materials as soon as possible, so as to obtain circuit boards on schedule and put them into other production activities.

Fourth, cost factors. When selecting high-frequency circuit boards, we should refer to the price sensitivity of the products. Because there are price differences in different fields such as communication, medical treatment or military industry, we should choose the circuit board with appropriate price and performance according to the range of the fields used.
