Claim:
A system for filling holes in a printed circuit board with a fluid fill material, the system comprising: a main body for receiving a vertically placed printed circuit board within the main body; a dispensing head for selectively dispensing a fill material onto the vertically placed circuit board, the dispensing head having a plurality of holes; a feeding reservoir containing the fill material, the feeding reservoir having a first end and a second end; an outlet system connecting the first end of the feeding reservoir to the dispensing head, the outlet system comprising a flow line connected to the first end of the feeding reservoir, wherein the flow line provides smooth laminar flow for the fluid material from the first end of the feeding reservoir to the dispensing head; a plunger located at the second end of the feeding reservoir; and an air cylinder for pushing the plunger into the feeding reservoir, thereby forcing the fluid material out of the first end of the feeding reservoir and into the dispensing head.
