摘要：
Apparatus and methods for a system and process for applying a flux coating to a circuit board by pulsing an airless spray gun on and off to achieve excellent circuit board through-hole penetration and uniform film thickness. An overspray collection system is provided which reduces overspray and increases material utilization and transfer efficiency. A gun positioning mechanism, which can be automated, accurately locates the gun relative to the circuit board.
