Latest trends in connector plastics development

With the continuous development of science and technology, 3C products are constantly updated, major cell phone, computer manufacturers are launching new models every year, and the connector industry is also in the process of continuous updating with the 3C products are also constantly undergoing a huge challenge. The following is a small editorial by the Yinji network to introduce the latest trends in the development of connector plastics is how, next please see this article one by one.

High-flow high-temperature connector trend is: standard → high flow low warpage → ultra-high flow low warpage For the time being, foreign manufacturers are in the ultra-high flow. Low warpage material research, ordinary some grades of our domestic technology is also able to meet the requirements. With the product height, width and the distance between the terminals become smaller, it is also necessary to material with high fluidity. At the same time to improve the fluidity, naturally, there will be a corresponding loss of some of the strength and toughness of the material, but also for the needs of the product, but also as far as possible to maintain the strength and toughness of the material. As well as heat resistance. Low dielectric properties of electronic equipment transmission speed is very important (transmission speed is getting faster and faster). In order to improve transmission speed, high-frequency products are more and more (higher and higher frequency), the material's dielectric constant also has requirements, the current high-temperature materials seem to be only LCP to meet the requirements of the dielectric constant <3, followed by SPS can be used as an alternative, but the shortcomings are still many.

Color demand due to the LCP appearance is not glossy, easy to have flow marks, and the dyeing performance is not very good, so the development trend of LCP tends to have a glossy appearance, easy to match the color, and high temperature process does not change color. To meet customer demand for product color. Waterproof cell phones and other 3C products for waterproof requirements are becoming more and more high, for example, the recent iPhone X waterproof is also one of its highlights, in the future, the popularity of waterproof will certainly be more and more high. At present, the main use of dispensing glue and silicone combination to achieve the purpose of waterproof. Long-term temperature resistance is wear-resistant under high temperature (long-term use temperature 150~180℃), creep-resistant (125℃/72hrs under load), and meets ESD requirements (E6~E9).
