The proposed masking dam protects ball grid array integrated circuit components from conformal coating overflow, preventing joint breakage and thermal mismatch. The masking dam includes a frame with an integrated seal, a cover, and a fastening mechanism. The frame is sealed to a circuit board surround a component, the cover is attached to the frame, and the masking dam is secured to protect the component.

BGA component masking dam and a method of manufacturing with the BGA component masking dam

A heater control structure for an ice protection system is disclosed that includes a first multi-role logic block having a first scheduler to schedule the operation of an array of heaters and a first controller to control a first group of heaters within the array of heaters, wherein the first scheduler communicates with a first private data bus and the first controller communicates with a second private data bus, and wherein the first scheduler and the first controller communicate with one another over a first pair of inter-channel data busses. The structure further includes a second multi-role logic block having a second controller to control a second group of heaters within the array of heaters and a second scheduler to schedule the operation of the array of heaters, wherein the second controller communicates with the first private data bus and the second scheduler communicates with the second private data bus, and wherein the second controller and the second scheduler communicate with one another over a second pair of inter-channel data busses.

Heater control architecture for an ice protection system

An ice protection system for a vehicle is disclosed which includes a plurality of de-ice power distribution units positioned proximate to a leading edge surface of the vehicle that is susceptible to ice accretion, at least two anti-ice power distribution units located within the vehicle, spaced from the de-ice power distribution units, and a point of power regulation located within the vehicle, spaced from the power distribution units, from which power is fed to the power distribution units through independent feeder wire bundles so as to distribute line current across the system in a manner that optimizes wire weight.
