Values & Tolerances Schematic

Spectrum Microwave knows that critical attention to artwork dimensions and tolerances is a paramount importance during a design packet transfer. To assist with this critical step in the design process, we provide as illustration as seen below, which includes suggested values and tolerances that should be followed in order to facilitate a complete and comprehensive design packet.
