Traffic Led Light Pcb Board Assembly

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…
