6.3 Using Press-Fit Nuts for Mounting the Module
A press-fit nut is pressed into the PCB from the bottom side with a special press tool. M2 sized press-fit nuts are suitable for the modules
(see Figure 9 and Figure 10) and are manufactured by PEM Fastening Systems ( www.pemnet.com ), part no KFS2-M2 (see Figure 11).
Be careful with the distance between the nuts regarding alignment, see the Mounting Holes section.
Figure 11: KFS2-M2 press-fit nut.
Spacer-pipes are recommended to use between the PCBs when press-fit nuts are used.
6.4 Using the J6 PCB solder pads
6.4.1 Host Board
The host PCB footprint should not contain any traces or vias under the module except the pads interfacing the J6 pads to avoid contact
with traces/vias on the module. The host pads which are soldered to the J6 pads should reach 0.5-1.0mm under the PCB and some mm
outside the module. No other pads than the J6 should be soldered to the host PCB. See section J2, J3 and J6 Connectors for more info
about the J6 pads.
6.4.2 Mounting process
We strongly recommend the modules not being soldered more than 1 time after shipping from connectBlue and that the modules are
mounted just before the host product is being soldered the last time. Although, connectBlue devices will withstand up to two reflows to an
absolute maximum temperature of 250°C.
The PCB in our modules is made of FR4-type with Chemical Gold Pads.
