The implementation of USB4 v2.0 and 240W fast charging technology in the Type-C interface field.
The EU has mandated a unified charging interface, passing legislation that requires all consumer electronics (including smartphones, tablets, headphones, etc.) to adopt the Type-C interface by the end of 2024. Apple has confirmed that the iPhone 15 series will fully switch to Type-C, triggering a wave of adjustments in the supply chain. The USB-IF association has released the USB4 2.0 standard, supporting ultra-high bandwidth up to 80 Gbps, and simultaneously with Type-C...
USB AM Puncture Connector - Expanding Applications in Industrial Automation Scenarios
The industrial automation scenario application extension USB AM piercing connector, due to its non-soldering and rapid assembly characteristics, has seen an increase in penetration rate in industrial control equipment (PLCs, sensors). Molex and JAE have launched waterproof and dustproof products with IP67 protection level. The cost advantage promotes the replacement of traditional interfaces in low complexity devices (such as smart home appliances and POS machines), where USB AM piercing connectors gradually replace Micro USB, mainly due to their assembly efficiency and yield advantages.
Production and Quality Improvement - Dongguan Factory Earns Zero Carbon Factory Certification
Dongguan factory has been certified as a zero-carbon factory by introducing photovoltaic power generation and bio-based plastic materials (reducing carbon footprint by 30%), making Dongguan production base the first connector factory in the industry to pass TÜV Rheinland carbon neutrality certification. The full automatic testing line has been put into operation with an investment of 20 million yuan to introduce AI visual inspection equipment, achieving 100% automated testing for contact resistance and insertion/removal life of Type-C interfaces, reducing customer complaint rate by 67%.
DP (DisplayPort) Series - DP Alt Mode and Type-C Integration Acceleration
The DP 2.1 standard and the 8K display ecosystem: VESA has released the DP 2.1 standard, supporting UHBR20 (80 Gbps) transmission rates. Combined with AMD's RX 7000 series graphics cards, this pushes the commercialization of 8K/120Hz gaming monitors. The integration of DP Alt Mode with Type-C accelerates the functionality of DP Alt Mode through Type-C interfaces, allowing lightweight laptops and tablets to directly output 4K/8K video. Dell, Lenovo, and other manufacturers are adopting this technology.
Market and Customer Breakthrough - Data Center Business Achieves a Year-on-Year Growth of 120%
Successfully penetrated the European automotive supply chain and signed a strategic agreement with Y Company, a German Tier 1 manufacturer, to provide LCP plastic cases + gold-plated Type-C connectors resistant to 180°C for its 800V high-voltage platform, with a contract value exceeding 200 million yuan. Data center business grew by 120% year-on-year, SATA Express hybrid connectors won orders from ByteDance and Alibaba Cloud data center projects, with monthly shipments exceeding 800,000 units.
The Employee Honor and Corporate Culture Construction Skills Competition has come to a successful conclusion.
The R&D team won the Annual Innovation Award. The high-speed connector group led by Engineer Long Tao was commended by the company for its breakthrough in DP 2.1 interface technology and awarded a team with overseas technical inspection slots. The Skills Competition concluded successfully, with the Production Department holding its first Precision Stamping Craftsman Competition. Yan Gong (with five years of seniority) took the championship with a tolerance control result of ±0.002 mm, breaking the company's record.
Technical Trends in Plastic Enclosures and Hardware - Accelerated Application of Environmental Materials
The application of environmentally friendly materials accelerates the tightening of EU RoHS 3.0 regulations, leading to a shift in connector housing materials towards bio-based plastics (such as PBT/PA66 with 30% plant fiber modification), which have been adopted in large quantities by Foxconn and Luxshare Precision. In the competition for hardware terminal manufacturing between precision stamping and MIM processes, Metal Injection Molding (MIM) technology is gradually replacing traditional stamping in small size and complex structure components (like Type-C tongue pieces), achieving an accuracy of ±0.01mm. High temperature resistance and EMI shielding..
Highlights of electronica 2025 in Munich
Highlights of electronica 2025 include TE Connectivity showcasing a 48V Type-C power module for automotive use, supporting large currents up to 15A. Amphenol introduced an ultra-thin board-to-board connector with a 0.5mm pitch, targeting the foldable smartphone market. Domestic manufacturer CCS made a technological breakthrough by launching its proprietary dual-row pierce USB AM connector, which is 30% cheaper than foreign brands.
