Mass Via Hole Filling Function
The PCB is placed horizontally onto the filling surface and clamped by the clamping system. The door is closed and the vacuum process starts.
The vacuum has built up after about 20 seconds. The plunger (air pressure controlled) is pressing the paste into the holes of the panel. The paste is stored in reusable cartridges. We supply different head´s for different panel sizes. The movements of the X- and Y-axis are controlled by servo motors. The touch panel display allows up to 50 recipes to be stored. All process parameters are part of the recipe. Max. 5 tracks and 4 steps are possible for each recipe.

Paste Delivery
As with the VCP vertical filling machines, the paste delivery is from a standard 12oz or 6oz or smaller cartridge. The paste is pressed into the via fill head via pneumatic pressure on the back of the plunger in the cartridge. Different head sizes can be used. If, however, a head size larger than 6” is required, then the pressure bar assembly must be exchanged against one that allows the capability of pressing a long head up to 24” long evenly across the entire width of the fill area. Also, as with the vertical VCP machines, face plates with different opening sizes can be used with a given head size.
