Plugging of pcb´s, via hole filling

Main applications:
This machine is designed to fill holes in printed circuit boards with conductive or non conductive paste. The hole filling can be applied in via and in blind holes. The filling from blind holes is possible in a double side mode in one step. The machine is equipped with a glass cover for visual quality control on both panel sides.

The Function:
AftOnce the printed circuit board in vertical position has been hanged upon pins, the door is closed and the vacuum process started. The vacuum has built up after about 30 seconds. The filling process begins with the paste by piston being pressed out of a cartridge into the bores whilst the squeegee being moved over the printed circuit board. Both the kiss pressure of the filling heads to the printed circuit board and filling pressure are adjustable. The vertical motion is realized by an adjustable servomotor. 
If there are still some hole voids, the operator can replug the same printed circuit board. That’s the great advantage when “plugging under vacuum”.
The paste is kept in refillable cartridges. Subject to the printed circuit format, different squeegee sizes are available.

Automatic Scavenger System: ES

Automatic Scavenger System 
This machine is designed for doctoring excess plugging paste from the surface of the printed circuit board. For doing so, the plugged panel is placed into the Automatic Scavenger System by hanging it on tooling pins and then the automatic process of squeegee blades wiping off the excess paste material on both sides of the panel is conducted.
