Abstract: A zone heater assembly of a reflow solder tool includes a gas deflector having a single-layer structure. The single-layer structure may include one or more gas-permeating patterns through which a process gas is to flow from one or more gas outlets to a gas exhaust of the zone heater assembly. The one or more gas-permeating patterns in the single-layer structure promote uniformity of gas flow through the gas exhaust and into a heating zone of the reflow solder tool. The uniformity of the gas flow of the process gas enables convection heat provided by the process gas to be uniformly distributed across the heating zone. In this way, the gas deflector described herein may decrease hot spots and/or cold spots in the heating zone, which enables greater flexibility in placement of semiconductor package substrates on a conveyor device of the reflow solder tool.
