The relationship between PCB copper thickness and current is an important factor in the use of heavy copper PCB. As the copper concentration increases, the total cross-sectional area of copper also increases, which reduces the resistance in the circuit. As we know, losses are devastating to any design, and copper concentration enables these PCB to reduce power budgets.
Current conductivity is an important factor, especially when processing low-power signals, and the current conductivity of heavy copper PCB is improved due to its extremely low resistance.
The connector is necessary for jumper connection. However, connectors are often difficult to maintain on traditional PCB. Due to the low strength of occasional PCB, the connector parts are usually affected by mechanical stress, but heavy copper PCB provide higher strength and ensure higher reliability.
The advantages of heavy copper PCB
The advantages of heavy copper PCB make it the top priority for the development of high-power circuits. The heavy copper concentration can handle high power and high heat, which is why high-power circuits have been developed using this technology. Such circuits cannot be developed with low-copper concentration PCB because they cannot withstand the huge thermal stresses caused by high currents and flowing currents. Heavy copper PCB are generally considered high current PCB because of their significant heat dissipation capabilities.
