With the continuous development of science and technology, 3C products are constantly updated, major mobile phones, computer manufacturers are launching new models every year, and the connector industry is also in the process of continuous update of 3C products is also constantly undergoing great challenges. Let's introduce you to the latest trend of the development of connector plastics, and then see the introduction of this article.
High flow
The trend of high temperature connectors is: standard → high flow low warpage → ultra-high flow low warpage
For now, foreign manufacturers are carrying out ultra-high mobility. The research of low warpage materials, some ordinary grades of our domestic technology is also able to meet the requirements.
As the product height, width and distance between terminals become smaller, high mobility of the material is also required.
At the same time as improving the fluidity, it will naturally lose some of the strength and toughness of the material, but also to maintain the strength and toughness of the material as much as possible for the needs of the product. And heat resistance.
Low dielectric characteristic
The speed at which electronic devices are transmitted is important (and getting faster and faster). In order to improve the transmission speed, more and more high-frequency products (higher and higher frequency), the dielectric constant of the material also has requirements, at present, it seems that only LCP can meet the dielectric constant<3 requirements, followed by SPS can be used as an alternative, but there are still many disadvantages.
Color requirement
Because the appearance of LCP is dull, easy to have flow marks, and the dyeing performance is not very good, the development trend of LCP tends to be glossy in appearance, easy to match color, and does not change color during high temperature process. To meet customer demand for product color.
Waterproof
At present, mobile phones and other 3C products have higher and higher requirements for waterproof, such as the recently released iPhone X waterproof is also one of its highlights, in the future, the popularity of waterproof will definitely be higher and higher. At present, it mainly uses the combination of dispensing and silica gel to achieve waterproof purposes.
Long-term temperature resistance
Wear resistance at high temperature (long-term use temperature 150~180℃), creep resistance (125℃/72hrs under load), meet ESD requirements (E6~E9).
