This document describes how to safely mount and use press fit type of EconoPIMTM and
EconoPACKTM products for the following part numbers shown in Table 1.
Press fit type : Products that can be mounted solder less to printed circuit board (PCB)
Press fit terminals have the characteristic shape shown in Fig.1(a). When the press fit terminal is
pressed into the PCB, contact pressure is applied from both sides of the terminals, and they were
deformed and inserted as shown in Fig.1(b). The deformation pressure makes it possible to mount the
product on the PCB solderless.
When handling the product, in addition to the contents described in this document, please check the
Warning and Caution in the product specification too.

2-1. Requirements for printed circuit board
Table 2 and Fig.2 show the recommended specifications of a printed circuit board (PCB).
The recommended specifications in Table 2 is evaluated based on IEC60352-5. When using a PCB
other than the recommended specifications, evaluation is required.
< Requirements for the PCB material >
Double-sided PCB in accordance with IEC 60249-2-4 or IEC 60249-2-5.
Multilayer PCB in accordance with IEC 60249-2-11 or IEC 60249-2-12.
For example, the through hole diameter should be in the range of 2.14mm to 2.29mm with properly
Sn/Cu plated sidewall. If the diameter is too small, problems such as damage to the terminals and
PCBs may occur during the press-in process. On the other hand, if the diameter is too large, a gap
will be created between the terminal and the PCB, causing problems such as vibration and shock,
resulting in reduced reliability.
In addition when mounting the module to the heatsink after mounting the PCB, holes for module
mounting are required on the PCB. (Fig. 2 (b)) These holes for mounting can be used as a guide pin
hole for the module fixing tool when inserting the module into the PCB.

2-2. Notes when mounting components on a printed circuit board
For press fit products, it is recommended that components be mounted in an area at least 5mm
away from the center of the press-fit terminals because the PCB near the press-fit terminals may be
deformed during the press-in process. Also, design the press-in/press-out tool to be used in such a
way that it does not affect the components.

2-3. The press-in and press-out process of printed circuit board
This section describes the procedure of the press-in and press-out process of PCB.
Table 3 shows the recommended press speed and load (average per terminal) during the press-in
and press-out process for the minimum and maximum PCB through-hole diameters.
If the press-in force is too low, there will be issues with the contact between PCB and the module
terminals. On the other hand, if the press-in force is too high, it can damage the PCB and other
mounted components.
Therefore, it is recommended to use dedicated machine and tools for the press-in and press-out
process. Fig.3 shows a photo of the press machine (example).

2-3-1. Press-in / press-out tool
During press-in/press-out of the PCB, use a tool for press-in/press-out to ensure that the press-fit
terminals and through holes are not misaligned. Examples of a press-in tool is shown in Fig.4 and a
press-out tool is shown in Fig.5.(example for M722 and M648)
Please refer to the appendix for the actual tool dimensions.
During the press-in process, pass the lower tool guide pins through the hole for the guide pins of the
PCB.
In the example of Fig.4, the module mounting holes are used as guide pin holes.

2-4. Soldering the module to the printed circuit board after press-out
It is possible to reuse a module after press-out. Remove the PCB carefully. However, since the
press-fit terminals after press-out is deformed compared with the unmounted state, please solder the
contact part of the press-fit terminals and PCB when remounting.
The recommended conditions for soldering the module to the PCB are shown below.
Terminal temperature : 245±5ºC
Time : 5±0.5sec
The recommended soldering temperature is defined as “terminal temperature”. This is different from
the preset temperature of the soldering equipment. Please set the temperature of the soldering
equipment according to the heat capacity of your PCB. Also, make sure that the resin temperature
below the module terminal during soldering does not exceed 260ºC.

2-5. Screw tightening to printed circuit board
This section describes the screwing method when mounting the PCB to the product.
1. Use M2.5 self-tapping screws to fix the product to PCB.
2. To fix the module with even force, first perform temporary tightening. Fig.8 shows the tightening
torque and sequence.
3. Perform final tightening in the same sequence as temporary tightening. The final tightening
torque should be within the range shown in Fig.8.

MT5F22233b
4. As shown in Fig.9, use screws with a diameter of 2.4 to 2.6 mm and a length of 7.0 to 10.0 mm
from the underside of the PCB.
5. Manual screwing is recommended. When using an electric screwdriver, optimize the parameters
such as tightening conditions to avoid mechanical damage. Check that the product is not
damaged after tightening. Also, the screwing speed should not exceed 300 rpm. It may result in
mechanical damage as shown in Fig.10.
