Description
The various tooling support options are described separately in this chapter.
The specifications for the options are tabulated below.
CAUTION
CAMERA DAMAGE.
Do not leave any unused tooling on the rising table in
the area behind the rear rail. If any object is left on the rising table outside
the board printing area, it could collide with the camera carriage as the
rising table moves to print height.

MAGNETIC SUPPORT PILLARS
The magnetic support pillars are positioned on the manual tooling plate by the
operator. These pillars can be positioned anywhere under the board to provide
board support.
Two types of support pillar are provided:
• Standard flat-top pillars (19mm) for supporting boards which are not
populated on the underside.
• Pin-top pillars (4mm) for supporting boards which are populated on the
underside. The pins are positioned so that they fit between the compo-
nents on the underside of the board.

VACUUM BOX TOOLING
The vacuum box is manufactured to the same height as the magnetic pins, ie
81mm, irrespective of the thickness of the board being printed. The vacuum
boxes can be constructed without top or bottom plates to allow for additional pin
support of the board. Provision for machining of top plates to accommodate
underside components is available. The box is located on the table by means
of dowels.
