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.

MULTIFLEX TOOLING
The MultiFlex tooling plate hardware consists of a hollow box constructed from
four adjustable side plates. The side plates are secured to the MultiFlex tooling
plate using magnets. The tooling plate is located on the tooling table by means
of dowels.
Board support is provided by double ended steel pins on a 5mm matrix. One
end is 3mm tapering down to 1mm to allow for support of densely populated
boards.
Vacuum (option) is achieved using the Venturi effect on the mains air supply.
The vacuum is variable by adjustment of the speed controller. A gauge on the
Venturi vacuum pump indicates the amount of vacuum. The speed controller,
solenoid and Venturi vacuum pump are mounted on a bracket and located at
the rear on the lower left hand side of the machine.
The solenoid valve and hence the vacuum is controlled from MultiMove card
(X12) in the machine controller enclosure.
The MultiFlex tooling plate is 14 inches x 10 inches. The tooling height is the
same as a standard magnetic tooling pin, ie 81mm.
The 3mm diameter tooling pins are placed on the 5mm pitch matrix according
to the particular board configuration, to support the board, and yet miss any
components, or features present.

DEDICATED TOOLING SYSTEM
The dedicated tooling system is a 3-piece construction comprising a plate
assembly which locates on a tooling tower and magnetic support pins that
provide support under the plate assembly when accommodating wide boards.
The system is manufactured to provide board support at the standard tooling
height of 81mm. The plate assembly can be specifically machined to accom-
modate underside components on customers products.
The tooling tower has dowel pin registration and is held in position on the
manual tooling plate by two magnetic clamps located in the vacuum chamber
of the tooling tower. Additional board support can be utilized with the optional
vacuum facility.
