9.1.1 Press-in tool
Make sure the press-in tool is larger than the driver PCB.
The recommended diameter of holes/ cutouts for the pins is 1.7 to 4 mm, depending on
positioning accuracy, as shown on Figure 12. Allow for at least 2 mm supporting space
around the pin (see
Figure 13
). An elongated cutout for several pins may be made if the
pins are close together. The PCB and module must also be positioned. The size and
position of holes and cutouts will be determined by the components on the PCB.
Cutouts for pins are to be 6 mm deep.
Figure 12: Recommended dimensions for the press-in tool
Recommended material for the press-in tool:
Tempered aluminum alloy grade 7075-T6 with 430 Mpa yield strength and 160 HB
hardness or
Steel-grade 21 MnCr 5 with 660 Mpa yield strength and 330 HB or better hardness
9.1.2 Support plate
The support plate positions and supports the module during press-fitting.
The recommended material for the support plate is:
o
ESD-proof POM (polyoxymethylene) or any metal alloy
9.2 Press-fitting parameters
Press-in force: 90 N / pin
– 150 N / pin
Press-in speed: 5 mm/s
– 10 mm/sThe total press-in force depends on the number of
pins, hole diameter and plating (type/quality) of the PCB.
