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.

PROFLOW STENCIL SUPPORT
The ProFlow Stencil Support unit provides stencil support when printing in the
ProFlow option and helps to avoid smearing paste onto the top of the stencil.
These are used mainly when printing boards that are narrower than the ProFlow
transfer head (300mm minimum).
The ProFlow Stencil Support is compatible with all tooling options. The stand-
ard height (when the adjustable tooling top is in the closed position) is 81mm.

Changeable Gauge
Plate
The Changeable Gauge Plate, standard thickness 3/16" (4.77mm), may be
changed in order to support larger stencil areas. These are easily removed and
held in position by fixed magnetic supports.
Tooling Bottom The Tooling Bottom is the fixed base for the stencil support with magnetic feet
attached for easy position on the tooling table.
Adjustable Tooling
Top
The Adjustable Tooling Top can be moved by releasing the 7mm hexagonal nut
securing it to the tooling bottom. The unit can be slid upwards, raising the height
of the support unit, to the desired height.

FORMFLEX TOOLING
Purpose FormFlex tooling is a fully automated tooling facility that conforms to any given
board profile, fully supporting the underside of a populated board and stencil.
FormFlex tooling array consists of 6 tooling modules with pin up/down control,
and each module contains 44 pins in two rows. The FormFlex array is held
magnetically to the manual tooling plate with the front unit being dowel located.
The FormFlex tooling height is 81mm standard tooling height, with a maximum
component under board clearance of 15mm.
With the board loaded and raised to print height, all the FormFlex pins are
extended using hydraulic fluid pressure until they meet the underside of the
board, stencil or component. Once all the pins are in contact, the fluid supply to
the pins is cut-off, automatically locking the pins in position. Variations in the
board layout can be accommodated as the force necessary to vary the height
of a single pin is small enough not to damage a component.
