  • Patent number: 11406024
    Abstract: A multi-layer circuit board is formed multiple layers of a catalytic layer, each catalytic layer having an exclusion depth below a surface, where the cataltic particles are of sufficient density to provide electroless deposition in channels formed in the surface. A first catalytic layer has channels formed which are plated with electroless copper. Each subsequent catalytic layer is bonded or laminated to an underlying catalytic layer, a channel is formed which extends through the catalytic layer to an underlying electroless copper trace, and electroless copper is deposited into the channel to electrically connect with the underlying electroless copper trace. In this manner, traces may be formed which have a thickness greater than the thickness of a single catalytic layer.

  • Patent number: 11392251
    Abstract: A method includes driving, by the master controller, transmitter electrodes with a first transmitter signal having a first sensing frequency while transmitting a first trigger signal to slave controllers, obtaining a location of an input object determined from first capacitive measurements determined by the slave controllers using the first trigger signal, and performing a resonant frequency scan. The performing the resonant frequency scan is by performing for each possible resonant frequency of resonant frequencies: driving, by the master controller, only a subset of the transmitter electrodes with a second transmitter signal having the possible resonant frequency while transmitting a second trigger signal to the slave controllers, wherein the subset corresponds to the location of the input object. The slave controllers demodulate a resulting signal according to the second trigger signal to obtain a second capacitive measurements for the possible resonant frequency.
