PROFLOW STENCIL SUPPORT
The ProFlow Stencil Support unit provides stencil support when printing with
ProFlow 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.

GRID-LOK TOOLING
Overview
Grid-Lok tooling is a fully automated tooling facility that conforms to any given
board profile, fully supporting the underside of a populated board and the
stencil.
The Grid-Lok tooling module is only available with a double row of tooling pins
with a 12mm pitch.
The tooling modules are available in two sizes:
The Grid-Lok tooling module is held magnetically to the manual tooling plate.

GRID-LOK TOOLING
29.8 Technical Reference Manual Chapter Issue 7, Jan 15
The Grid-Lok tooling system can be configured to handle the following board
sizes:
• Minimum board size - 38mm x 50mm
• Maximum board size - 254mm x 508mm
• Board thickness - 0.4mm - 5.0mm
With the board loaded and raised to print height, all the Grid-Lok pins are
extended using pneumatic pressure until they meet the underside of the board,
stencil or component. After a set period of time, the locking mechanisms of the
tooling modules are activated and the pins remain in this position until the
system is reset.
The Grid-Lok system incorporates two modes of operation, manual or auto-
matic.
In manual mode, the tooling pins conform to the board profile and remain in that
position until the reset button is pressed.
In automatic mode, the tooling pins conform to each board before it is printed.
