Three Characteristics of Thick Copper Board
The circuit board is made of copper clad laminate with a layer of copper foil on both sides of the copper clad laminate. When the thickness of the copper foil is greater than or equal to 2OZ, it is defined as a thick copper board , so why do we make such thick copper, and what are the characteristics of the thick copper board? 1. C arry H igh C urrent In the case of a certain line width, increasing the copper thickness is equivalent to increasing the cross-sectional area of the circuit, so the thickening of the copper foil can make the circuit board carry a larger current. 2. R educe T hermal S train The conductivity of copper foil is small (conductivity is resistivity; metal conductors are divided into: silver → copper → gold → aluminum → tungsten → nickel → iron.). In the case of passing a large cu...
