Abstract:
A method for making a printed circuit board having jumper lines, comprising the steps of:a) determining a pre-estimated value of an effective dielectric constant; a1) determining a shortened size of a microwave circuit according to the pre-estimated value of the effective dielectric constant and a used working frequency; a2) making a printed circuit board containing the microwave circuit according to the shortened size that is determined; b) coating or printing a high dielectric value material on the printed circuit board to form an isolation layer; c) forming multiple pads in the isolation layer of the high dielectric value material, thereby exposing part of the printed circuit board not covered by the high dielectric value material; and d) coating or printing a high conductive material on the isolation layer of the high dielectric value material to connect the multiple pads, thereby forming a planar jumper layer that is connected to the printed circuit board through the pads.
