Why is 1.6mm the default “standard” PCB thickness?

1.6mm PCB thickness balances rigidity, cost & SMT reliability. Thinner boards risk warping; thicker add bulk. Choose based on mechanical stress, layers & thermal needs. Simulate early to prevent failures.
What is the standard PCB thickness?

PCB thickness impacts reliability & cost. Default is 1.57mm for compatibility. Choose 1mm for wearables or 2.36mm+ for high-power/industrial. Mind layers, signals & heat.
