In the field of consumer electronics, connectors are indispensable parts. With the acceleration of 5G technology, the need for high-frequency and high-speed transmission, as well as the lightness, miniaturization and high-speed of consumer electronics products, connectors are also developing in this direction.
1、 mechanical properties (1) sufficient strength and rigidity (i.e., terminal holding force) (2) excellent toughness, Including terminal assembly, swing test and drop impact. 2. Thermal performance (1) lead-free SMT soldering process (plastics require direct high temperature resistance) (2) lead-free wave soldering process (plastics require indirect high temperature resistance) (3) temperature and humidity cycle resistance and long-term use temperature (RTI index). 3. Electrical performance (1) thermal insulation resistance (voltage resistance test, Electronic industry is mostly weak current) ② Dielectric constant and loss factor (high frequency products require low dielectric and low loss) ③ After environmental testing, it can still meet the requirements of electrical performance testing 4. Fireproof and environmental protection performance ① UL94V0 ② Compliance with RoHS and other environmental regulations ③ Consistent with halogen-free trend 5. Physical and chemical properties ① Chemical corrosion resistance (solder paste, Salt spray test, etc.) ② UV light resistance (appearance or outdoor product requirements) ③ Water absorption capacity (MSL-humidity sensitive level) ④ Good dimensional stability, thermal expansion coefficient in line with the general, LCP materials can reach level 1, some long-chain nylon, such as PA9T, PA10T can reach level 1, most high-temperature nylon is level 2. PA46, on the other hand, has a lower MSL rating because of its stronger water absorption capacity. Appearance and coloring of 6、 ① Good dyeing performance, in line with customization requirements ② High temperature SMT color stability 7. Processability ① Wide cutting window, low rust, low corrosion ② Some products require high flatness (low warping characteristics) ③ High flow rate (future products lighter)
