Rev. 2.0
5.9.5 Vacuum level
Vacuum levels lower than 0.4 bar shall not be applied on sensor component. Fast pressure
changes of over 0.5 bar/min should be avoided.
5.9.6 Air blowing
Heavy compressed air blowing directly onto sensor component shall be avoided.
5.9.7 ESD
Sensor components are electrical devices. Sensor components should be handled under good
ESD practices and ESD discharges should be avoided. The following numbers are absolute
maximum ratings:
±500 V charged device model
±2 kV human body model
5.9.8 Moisture
Sensor components are moisture sensitive devices, classified as MSL3 level. Guidelines defined
by IPC/JEDEC J-STD-020D shall be followed.

Hand Soldering Guidelines
For hand soldering of the DIL component, Murata recommends eutectic tin-lead solder due to the
lower melting point compared to lead-free solders. Key thing is that as soon as the solder flows the
soldering iron must be removed from the board. The package maximum temperature should be
kept under 245ºC and all mechanical stresses in the pin should be minimized. It should be noted,
that also PCB material might damage if too much heat or force is used.
Generally the hand soldering of the DIL component can be done in two different ways:
Method A
: Soldering of components with tin wire and soldering iron
Method B
: Soldering by applying solder paste onto PCB land pads and
then
using reflow heating
or soldering iron to melt the paste and achieve the soldered joint.
6.1 METHOD A: Soldering of components with soldering iron
Use the tin wire and soldering iron to solder the component onto PCB. Do not touch the package
plastic body with the soldering iron, soldering iron should touch only the PCB pad and through that
the heat should be conducted to the tin wire and component lead. Murata has used 315ºC setting
temperature for component soldering. The temperature on the tip of the tool is 270...275ºC.
Soldering process takes only few seconds for each pin. For leaded soldering we have used
Multicore Sn60Pb40 and for lead-free soldering Almit KR-19SHrma flux-cored solder wire.
