DuPont™ Pyralux® APR
Pyralux® APR is a copper clad laminate with an embedded resistance layer allowing designers to move resistors from the surface to within the PCB itself. APR embedded resistance is ideal for any market place, from mil-aero to commercial, when trying to embed passive surface resistors to decrease overall package thickness. APR derives its material robustness due to it’s base material being identical to that of Pyralux AP.
