JLCPCB offers High-precision Multilayer PCB with impedance control at no extra charge Learn about our PCB laminate material and controlled impedance. . The JLCPCB Impedance Calculator computes track width values and recommended stack-ups from user-input values of board thickness copper. A 2 layer board is all core A 4 layer board can either use 2 cores and one prepreg but typically 2 prepreg layers and one core. 02mm 787 mil is nominal thickness of 7628 prepreg Use 71 mil as the thickness when the controlled..
