OVERVIEW

FormFlex 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 standard Formflex tooling system configuration of six tooling modules 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
FormFlex tooling array consists of 6 tooling modules, each module containing
44 pins in two rows. The FormFlex array is held magnetically to the manual
tooling plate. 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. The pins remain in this position supported by the
reservoir of hydraulic fluid until the system is reset.
Once the tooling has conformed to the board profile, any force exerted on the
pins, in a tooling module, is caused by differences in board profile. Variations

in board layout, component tolerances or board misalignment can cause the
pins to displace. The resultant force on the pins is spread across all unaffected
pins in the tooling module raising them proportionally to the downward force.
The system therefore self compensates for any anomalies in board profile
without detriment to overall board or component support, figure below refers.
Figure 1-3 FormFlex Pin Displacement
Three of the solenoid valves on the FormFlex sequencer are used to control up
to 15 tooling modules. The solenoid valves are controlled by the M34 control
pod, mounted on the FormFlex sequencer assembly, which operates each
solenoid valve in turn with a 20 second delay allowing all the FormFlex pins on
one set of tooling modules to be raised before the next set is activated.
