Traffic LED lights are installed along roadsides or on bridges and are susceptible to vibrations from passing vehicles, typhoons, earthquakes, and other impacts. Customers require PCBs with strong vibration and shock resistance, meeting automotive PCBA vibration standards (such as the ISO 16750 automotive electronics vibration standard). PCB processing optimization: Component fixation: Components weighing ≥0.5g (such as inductors and large capacitors) are fixed using epoxy glue (with a bonding strength of ≥5N) to prevent component detachment due to vibration (detachment rate ≤0.01% @ 10G vibration).

Wiring design: PCB wiring utilizes curved routing (avoiding right-angle routing), with a trace width ≥0.2mm and a copper thickness ≥35μm, to enhance wiring resistance to vibration fracture (fracture rate ≤0.001% after vibration testing). Structural reinforcement: PCB edges are reinforced with ribs (e.g., FR-4 reinforcement plates with a thickness of ≥1mm) to enhance overall shock resistance (passing IEC 60068-2-27 shock testing, 100G half-sine shock, with no structural damage). Customers will require a vibration and shock test report (e.g., 10-500Hz vibration, 10G acceleration, 2 hours duration; 100G shock, 11ms duration). After testing, the PCB board must demonstrate normal function, with no loose components or abnormal performance, ensuring it can withstand vibration and shock during installation and use.

In the context of overseas transportation infrastructure upgrades (such as smart traffic lights and road warning lights), traffic LED light PCBs, as core hardware carriers, undertake key functions such as LED driving, signal control, and environmental adaptability. Their performance directly determines the brightness stability, service life, and intelligence level of traffic LED lights. Furthermore, this product requires deep integration with network switches (intelligent traffic data transmission), PCB processing (hardware quality assurance), and automotive PCB assembly (high-reliability technology benchmarking) to meet the core requirements of international customers for transportation equipment: high stability, strong environmental adaptability, and intelligent compatibility. When purchasing, international customers (such as transportation equipment manufacturers, municipal engineering contractors, and intelligent transportation solution providers) prioritize product technical details and application suitability based on five key criteria: optical performance and drive stability, environmental adaptability and durability, intelligent compatibility and data interaction, PCB manufacturing quality, and compliance certification and cost. The following article comprehensively analyzes these key concerns, drawing on the specifics of international transportation scenarios. This will provide targeted content support for Google website promotion and help expand our product into the overseas transportation LED equipment market.
