Integral Planar Resistors Save Circuit Board Space

摘要

Planar resistors fabricated as part of a printed-circuit-board (PCB) laminate material provide circuit designers the means of saving board space and assembly costs at the same time. The resistors are formed on special resistive layers that are bound to a PCB dielectric material, such as polytetrafluoro-ethylene (PTFE). The PCB dielectric is also laminated with electro-deposited copper for forming transmission lines and other circuit features in stripline and microstrip technologies, in addition to the embedded resistors.
