Case Studies of Our Metal Clad PCB Project

Case Name: Metal Clad PCB Solution for High-Power LED Street Light Cooling System

Client Background:

A European urban lighting equipment manufacturer plans to upgrade traditional high-pressure sodium street lights to high-brightness LED street lights to reduce energy consumption and extend service life. The original design used FR-4 substrate, which caused severe LED chip overheating and significant light degradation during prolonged full-power operation, leading to high maintenance frequency and substandard lifespan.

Core Issues:

• LED junction temperature exceeded 105°C, causing approximately 20% reduction in light efficiency;
• FR-4 substrate insufficient cooling in ambient temperature range of -20°C to 50°C, resulting in street light lifespan of only approximately 20,000 hours;
• High urban maintenance costs due to frequent lamp replacements.

Solution:

Material Selection

• Aluminum substrate with thermal conductivity of 2.0 W/(m·K) replaces traditional FR-4 (approximately 0.3 W/(m·K));
• Dielectric layer thickness of 0.1 mm ensures electrical isolation strength >2 kV while maintaining efficient thermal conduction.

Thermal Design Optimization

• Dense thermal vias placed beneath LED solder pads rapidly transfer heat from chips to aluminum substrate;
• Aluminum substrate back directly contacts heat sink housing, forming an integrated cooling path.

Manufacturing Process

• High-reflectivity white solder mask applied to enhance light output efficiency;
• Surface finish with ENIG (Electroless Nickel Immersion Gold) ensures solder joint reliability and environmental durability.

Implementation Results

• Thermal Performance Improvement: LED junction temperature reduced to below 85°C, light degradation decreased from 20% to less than 5%;
• Lifespan Extension: Average street light lifespan increased to 50,000 hours, meeting urban lighting needs for over 10 years;
• Cost Savings: System energy efficiency improved by approximately 15%, maintenance cycle extended from 2 years to over 7 years, saving approximately 30% in total lifecycle costs.
