Decreasing the risk of fire in USB-C Connectors
USB-C connectors are becoming the consumer electronics industry’s most widely used data and power interface. As their usage grows, so do the risks of premature failures or fire hazards if manufacturers choose the wrong materials.
Modern consumer electronic devices, such as notebooks and docking stations, are designed to process more power faster. While standard USB 2.0 or 3.0 connectors process 10W of power, USB-C cables process 27W
The smaller pitch in USB-C connectors creates insulating walls between connector pins of only 0.2mm (thinner than those in previous generations). Thin-walled insulating materials need to demonstrate superior resistance to electrical tracking in high voltage environments to prevent potentially serious fire hazards. Consequently, tracking resistance of insulator plastic becomes key for product reliability.
