Base Unit; Soldering Head; Placement Head - Weller WQB 3000 Mode D'emploi

Because the adhesive strip is recessed, the placement of the component is not hindered. The component
that is to be soldered is placed on the template. The inner series of perforations (small openings) makes it
possible to centre the component precisely on the template.
The vacuum on the placement head will now be switched on. Lowering the placement head will cause the
component to be taken up and lifted from the metal template.
