Inert gas air horn distribution device

摘要

An inert gas air horn distribution device employs a labyrinth (46) with a baffle to clean the nitrogen gas used to deposit flux on circuit boards (12) before wave soldering operations. The baffle (62) diverts the gas flow causing heavier flux particles to collect in the labyrinth (46) while the lighter gas exits for use in depositing flux on the circuit boards. The labyrinth cleans the gas thereby keeping the knife clean which produces more uniform results with less maintenance. <IMAGE>
