A surface-mounted integrated circuit (IC) package is disclosed that has unwanted flux removed from surface-mounted IC. A bottom termination component (BTC) includes lands and a thermal pad. The lands provide an electrical connection from the BTC and the thermal pad provides heat transfer from the BTC. The thermal pad includes vias that are configured to remove flux generated from solder applied to the surface-mounted IC as the surface-mounted IC is assembled. A printed circuit board (PCB) is mourned to the BTC and is electrically connected to the BTC via the lands and receives heat transfer from the BTC via the thermal pad and includes a reservoir. The reservoir is configured to pull flux positioned between the lands into the reservoir as the flux is generated from the solder applied to the surface-mounted IC as the BTC is mounted to the PCB and as the surface-mounted IC is assembled.

Removing unwanted flux from an integrated circuit package

An electronic lock system including an access control device configured to provide system instructions, an interface module electrically coupled to the access control device and configured to transmit RF signals in response to system instructions received from the access control device, and a plurality of wireless electronic door locks each configured to wirelessly communicate with the interface module. Each of the wireless electronic door locks includes a controller and a wireless receiver operatively connected to the controller, the wireless receiver including a first antenna defined as a circuit board trace and a second antenna, spaced from the first antenna and defined as a circuit board trace. Each of the first antenna and the second antenna include one of a monopole antenna and a fractal antenna. The controller is configured to switch between the first antenna and the second antenna to receive a wireless signal having a greater signal strength.

Antenna diversity implementation for wireless locks

An apparatus and method is disclosed for electronic locks with a selectable power off function. The electronic lock includes an electronic controller disposed within a lock housing and operable to control a state of the lock between locked and unlocked positions. An electronic actuator electrically coupled to the controller is movable between first and second positions corresponding to a locked position and an unlocked position of the lock, respectively. The electronic lock further includes at least one electrical energy storage device and a selector switch coupled to the controller to define a desired state of the lock between one of an electrically locked (EL) and an electrically unlocked (EU) state in an electric power off condition.
