  • Patent number: 9659889
    Abstract: This disclosure relates generally to generating a solder-on-die using a water-soluble resist, system, and method. Heat may be applied to solder as applied to a hole formed in a water-soluble resist coating, the water-soluble resist coating being on a surface of an initial assembly. The initial assembly may include an electronic component. The surface may be formed, at least in part, by an electrical terminal of the electronic component, the hole being aligned, at least in part, with the electrical terminal. The solder may be reflowed, wherein the solder couples, at least in part, with the electrical terminal.

  • Publication number: 20050069063
    Abstract: A method and apparatus are provided for broadband cancellation of interference signals. A signal transmitted on one communication path acts as an interference signal to a receiver on a second communication path in the system. In an embodiment, a signal transmitted from an antenna using one wireless standard, or protocol, acts as an interference signal for another antenna, co-located in the same system, using another wireless standard, or protocol, and operating in the same or nearby frequency bands. A time delay is applied to a signal sampled from the interference signal to provide substantially broadband cancellation of the interference signal. The sampled signal may be attenuated to match the amplitude of the interference signal on the second communication path. Coupling of the sampled signal from one communication path to the other communication path can provide an 180° phase shift to the sampled signal.
