Tool Operation:
1. Position the Memory Module with the printed circuit board in the correct orientation as shown in Figure 1.
Make sure that the Memory Module is seated correctly in the PCB/Connector support fixture. (Supplied by the
customer. See Page 3.)
Note:
For the 284 circuit assemblies, remove two knockout pins from each end of the tool (See knock out pin
replacement).

2. With the Memory Module supported with the customer supplied fixture, the Extraction Tool can now be placed
on the back side of the printed circuit board. See Figure 2.
3. The printed circuit board thickness will determine the method of location for the terminal knockout pins (the
stock tool supplied has all terminal knockout pins extended thru the Pin Hold Down Plate). This is used when
the terminals tips are recessed inside the circuit board board.

Note:
When the printed circuit board thickness is thinner and the terminals are protruding through the printed
circuit board, remove the Terminal Spacer (4) one at a time by removing the shoulder screw and sliding the
spacer off. Replace the shoulder screw one at a time and tighten. (The Terminal Spacers can now be stored
on the Pin Hold Down Plate using the (2) M4 holes with M4 button head screws.)

4. Place Extraction Tool flatly on the backside of printed circuit board allowing all pins to enter the correct related
terminal holes. All knock-out pins should enter the matching holes. If all pins are not in the terminal holes,
slide the Extraction Tool slightly in a circular motion until all pins fall into the holes.
5. When the printed circuit board is thinner (see note above) the knockout pins will be retracted in the Pin Holder
Plate. Place Extraction Tool flatly on backside of printed circuit board allowing the terminals to enter the holes
in the Pin Holder Plate. All terminals should enter the matching holes in the Pin Holder Plate. If all terminals
are not in the plate holes, slide the Extraction Tool slightly in a circular motion until all terminals fall into the
holes.
6. The Memory Module Terminals are now ready for

removal from the printed circuit board. Apply an
equal force across the length of the Pin Hold-

Down Plate. The Pin Hold-Down Plate will push

all the knockout pins downward all at once and will
push all the terminals out in one motion. The

Plate contacts the Pin Plate.
CUT-OUT
7. When all terminals have been pushed out of the
SHORT

printed circuit board the force on the Pin Hold-
Down Plate can be removed. The knockout pins
will retract back.
8. Lift the printed circuit board off from the Support
PIN

Fixture. If the Memory Module is still on the
KNOCK

the housing. See Figure 3.
9. With the Memory Module removed, inspect the
PIN
area. Use long pliers to remove any remaining
PLATE
terminals that are still in the printed circuit board
and remove any additional debris if present.
Figure 4
Printed Circuit Board (PCB) Support
The DDR4 DIMM Memory Module connector requires a PCB/Connector support fixture when removing the
connector from a PCB. To prevent printed circuit board damage a support fixture should be located directly
beneath the connector being removed. This also will prevent any possible damage to adjacent connectors.
Due to the custom nature of every application, Molex does not offer any PCB/Connector support fixtures. The
customer must supply their own support fixture.
When designing the support fixture, clearance must be provided for the connector and terminals being removed
and to all adjacent connectors.
CAUTION:
To prevent injury, never operate any press without the guards in place. Refer to the press
manufacturer’s instruction manual.
CAUTION:
Molex application tooling specifications are valid only when used with Molex connectors and tooling.

Knock Out Pin Replacement
To replace a broken or damaged knock out pin:
1. Remove the (4) M3 SHCS holding the pin hold down plate to the pin holder plate.
2. Remove the (4) shoulder screws.
Caution:
The pin hold down plate has springs below it that will release as the last shoulder screw is removed.
3. Move the pin hold down plate aside and identify the pin(s) to be replaced.
4. Using a tweezers or small pliers, grip the head of the pin and pull it out of the pin holder plate.
5. Install the replacement pin, making sure it goes through the pin holder plate and the pin plate. If any
obstruction is felt, remove the pin and inspect the holes for debris.
6. Place the pin hold down plate and the (2) springs on the pin holder plate; the long cut-out on the pin holder
plate is located over the larger group of pins.
7. Reinstall the (4) shoulder screws and the terminal spacers, (if used).
8. Re-install the (4) M3 SHCS.
