• Embedded resistors in printed circuit boards (PCBs) are fabricated to provide high integration, improved electrical performance, and reduced parasitic capacitance and inductance in the high-frequency and high-speed environment. At present, the embedded resistance errors caused by etching metal film accuracy are generally more than 20%. In this work, real-time monitoring technology is developed to precisely control the resistance of electroless-plated embedded resistors. During the deposition process, the resistances of embedded resistors are monitored until reaching the targeted resistance, realizing the very ideal resistance error lower than 10%. Arbitrary shapes including serpentine and zigzag structures of embedded resistors are attempted to validate the practical capability of this approach. Reliability Characterization experiments such as high-temperature and high-pressure lamination, thermal shock and thermal cycles confirm the thermal and mechanical stability. It is demonstrated that the embedded resistors through real-time monitored electroless plating have tremendous potential in the manufacture of high-frequency and high-speed PCBs.
