MASS-PCB, SV200WV, Abrasive Planarizations System

The grinding machine SV 200 WV serves to remove the excess plugging paste from
printed circuit boards and inner layers following the Via Hole Plugging process. That
allows getting a flat uniform surface of the copper surface.
The grinding disk is driven by a servo motor, the x-y movement is manual by

The basic frame is made up of a stable welded stainless steel rack. The outer jacket
is made up of canted stainless sheet metal sheets. All the sheets allow be opening
with ease by entering catch locks and removing for allowing access.
The grinding head is covered with a hood with aluminium glass profiles. The plant is
built up and designed such that all components are clearly arranged.

Cooling water is transported via pump to the grinding head. On the bottom of the
machine you can find the belt filter equipment, where the cooling water is filtered.

The inner- or outer-layer of the printed circuit board is fixed on the aluminium working
plate by vacuum.
The working area is protected by safety glass. The specific linear guides and the
adjustable grinding pressure result in an excellent grinding performance and prevent
the copper foil from possibly being ground through. The grinding head can be
lowered to the printed circuit board with an exactness of 0,22 μm (0,0056 mil).
One turn (100 digits) eaquals 22μm (0,56 mil).

MASS-PCB, VHF300, Vacuum Paste Applicator

5/2015 vintage.


Description of VHF300 Plugging Machine Series
- Max. panel size 24 x 30”
- Thickness range is 2mil to 250 mil thick
- The machines are available in various functional levels:
o VHF 20: Manual X/Y moving head
o VHF 200: Automatic Y axis control, but manual X axis positioning o VHF 300 / 300V: Automatic Y & X axis control with or without vacuum

Possible head sizes range from 1 to 9 inches, whereby the limit for the VHF 20 is 2 inches (due to manual movement of the head).
The to-be filled panel is placed on a flat surface with a backer board or material underneath. The backer material is needed in order to allow the air that is displaced by the paste in the holes to escape.
Different size via filling heads or heads with different paste can be exchanged within minutes. The entire head with paste delivery is removed or installed as one assembly. This allows the complete assembly to be stored in a refrigerator or as needed.
