How to solve the problem of substrate size changes during the production of circuit boards?
Reasons for changes in the size of the substrate during the circuit board production process:   The difference in the warp and weft directions causes the size of the substrate to change; due to the lack of attention to the fiber direction during shearing, the shear stress remains in the substrate. O
