Patent ID: 8444770

Claim:
A method for cleaning components of a system for filling holes in a printed circuit board with a fluid fill material, the method comprising the steps of: removing the components being a dispensing head and a manifold connected to the dispensing head, the removal being to separate the components from the filling system; coupling a supply line for air to the manifold and placing the dispensing head and manifold in a first container; firstly evacuating excess fill material from the dispensing head and manifold by passing air through the dispensing head and manifold while in the first container; placing the dispensing head and manifold in a cleaning tub, the cleaning tub being different to the first container; attaching the manifold to a solvent pump line through a nipple attached to the cleaning tub; secondly flushing the dispensing head and manifold with a flow of solvent from the solvent pump line; removing the manifold and dispensing head from the cleaning tub; re-coupling the supply line for air to the manifold and re-locating the dispensing head and manifold in the first container; and thirdly evacuating excess solvent from the dispensing head and manifold by passing air through the dispensing head and manifold.
