Analysis of RF Connector Manufacturers' Choice of Engineering Thermoplastic Materials

According to Liu engineers, engineering plastics have such key characteristics as good toughness, dimensional stability, high impedance, chemical resistance to corrosion, short-term thermal stability, and long-term anti-aging properties. These advantages cannot be achieved by other materials. He also mentioned that the choice of this material is not only because it has these advantages, but also from another perspective, it is also an inevitable result of technological development.

In recent years, the connector's production and development technology trends have dramatically changed the connector market. With the prevalence of high sealing and micronization trends, today's connector designs require higher performance in a smaller space, and therefore a thinner wall thickness. The plastic raw material should be able to meet the design of filling a thin wall on a longer connector body and maintain the original performance while also meeting the cost and production man hours requirements.

People are now developing more fluid plastic materials to meet thin requirements and allow for faster production cycle times. Today, plastics have been exposed to high temperatures during the manufacturing cycle and subsequent molding cycles. For example, installing smaller components on high-density circuit boards, surface-adhesion technology has gradually been adopted, and a more reliable integrated circuit board can be provided at a lower price. This apparent trend in the connector industry requires connector materials to have better high temperature performance, lower voltage withstand performance, and lower cost.

Due to the continuous updating of connection technologies, connector designs are constantly changing. Along with this, the requirements for the performance of plastic raw materials for connectors have also changed dramatically. In fact, for connector plastics, designers, manufacturers, and end users of connectors are constantly introducing new features and higher performance requirements, that is, good temperature and physical properties at the same time in these critical places.

Liu engineer concluded that the performance of the connector body largely depends on the engineering physics used. The connector body must have good physical properties and manufacturing properties. The polymer must provide good toughness and dimensional stability while having electrical properties such as high impedance and insulation. When designing raw materials, designers are combining various aspects of the actual situation. After strict comparison tests, the materials are selected. Only in this way can the connectors work more stably.
