2.1
Printed Circuit Board Support
The GbX ? tooling requires up to 10 lb. per pin of
force to press the connectors into the printed circuit
10. Press the connector into the P.C. board and
observe for any deflection of the board when the
ram is at the bottom of its stroke.
boards. Therefore, a backup or support is required
to prevent damage to the P.C. board. The support
fixture should have clearance for the connector
terminals when they protrude through the underside
of the P.C. board. It is also recommended that the
support fixture have locating pins. Due to the
custom nature of each application, Molex does not
supply support and locating fixtures, the customer
normally supplies them.
The following is one simple way of making a P.C.
board support and locating fixture:
1. Locate a suitable piece of material for the
backup. It should be approximately 3/4 inch
thick and same size or a little larger than the
printed circuit board to be used. While
aluminum could be used, a rigid nonconductive
material such as a phenolic is preferred. (A
stack of scrap P.C. boards of suitable size could
be fastened together and used.)
2. Obtain a scrap P.C. board like the ones to be
assembled. Attach this board to the material
from step 1.
3. Using an oversize drill bit, drill through each
hole where a pin from the connector will go.
Drill deep enough into the lower material to be
certain the pins do not bottom out when inserted
(at least 5mm [0.20in] deep).
4. Locate two (2) holes on the P.C. board to use as
locating points. Drill for and mount suitably
sized dowel pins in these two locations on the
support fixture.
5. Clear out the support for any components
mounted on the underside of the printed circuit
board.

Press Stroke Adjustment
Most presses have some means of adjusting the
stroke; please refer to the appropriate manual (for
the press being used) for press stroke adjustments.
The stroke should be adjusted so that when the
press ram stops in the down position, the bottom of
the connector is flush to .25mm (.010 in.) above the
surface of the P.C. board. See Figure 2-1.

Installation
The only installation required is when you need to
install insertion modules into a tooling holder. To
do this, use the following procedure:
1. Along the lower edge of the tooling holder is a
row of M3 set screws, (See Figure 2-2), back
these out so that they do not protrude into the
inside of the holder.
KEYWAY
6 Place a P.C. board on top of the support,
located by the two pins, and check that the
holes for the connector pins are aligned.

7. Pre-insert a connector in the P.C. board in the
correct position.
8. Insert the press-in tool of proper size into the
connector.
9. Place the support with the P.C. board under the
press ram.
2. Slide the insertion modules into the tooling
holder in the proper order. See Figure 2-3.
The modules are keyed so that they cannot be
put in backwards.
