The HybridPACK™ 2 offers two guidance holes marked on the Figure 2 with the colour blue.
These guidance holes offer assistance by mounting the PCB on the module and allow
automated assembly.
To avoid damage or splitting of the stand-off, straight insertion of the screw into the stand-off
has to be observed during assembly (Figure 3).

The recommended screws and torques are based on laboratory tests. Depending on screws
and tools used, it may be necessary to adapt the assembly process accordingly.
After mounting the PCB the solder process (manual soldering, selective soldering or wave
soldering) may begin. When adhering to this sequence of assembly, the mechanical strain to
the solder points can be minimised.
During the entire soldering process care needs to be taken that neither a too high soldering
temperature nor a too long process time at the auxiliary pins overheats the plastic case and
thus deforms it.
According to IEC 68 section 2, a maximum solder temperature of T=260°C for a maximum
process time of t
max
≤
10s has to be observed during the solder process.
Further information regarding solder processes can be referred to the application note
AN2005-06 “Soldering Econo und Easy modules”.
Instead of directly soldering, the PCB could also be mounted onto the module through
connectors. Such electrical connection between PCB and module can use every connector
which is designed for a pin cross-section of 0,64 x 0,64 mm, especially JST connector type
"09HVD6B-EMGF-NR". The module auxiliary terminals (pin connectors) are designed
especially for fitting to the JST connectors (surface and dimensions).
