ENIG HASL Thick Copper PCB Assembly 3-20 oz/ft² for Automotive & Power Electronics
Heavy copper PCBs (also known as thick copper or power PCBs) feature significantly thicker copper layers ranging from 3 oz/ft² to 20 oz/ft² or more, compared to standard PCBs with less than 2 oz/ft² copper thickness. This enhanced current-carrying capacity makes them ideal for high-power applications in demanding industries.
Minimizes signal loss and distortion, ensuring clear and accurate data transmission even at elevated frequencies for telecommunications and data applications.
Utilizes materials with low dielectric constants and loss tangents to reduce energy loss during signal transmission.
Withstands elevated temperatures without degradation, maintaining integrity and reliability in heat-generating applications.
Enables accurate impedance management critical for maintaining signal quality in RF and microwave applications.
Exhibits superior electromagnetic compatibility with minimized EMI and enhanced signal integrity.
