PCB Layout
When laying out the QPI-6 EMI filter it is important for the
designer to be aware of the radiated EMI field that all
converters emit and to place the QPI-6 outside of this field
area. It is also recommended that the bus lines feeding into
the QPI filter are not routed such that they lie between the
QPI and the converter, or that their copper planes over-lap on
inner layers. This can cause EMI noise to be coupled from
input to output via the parasitic capacitance between the
planes.
In Figure 24, the QPI-6 is located ~1.5 inches from the
converter’s input pins, and the BUS voltage pins are located
on the side farthest away from the converter, to keep the
radiated EMI from by-passing the filter and coupling directly
to the BUS feeds.
Post Solder Cleaning
Picor’s LZ version QP SIPs are not hermetically sealed and
must not be exposed to liquid, including but not limited to
cleaning solvents, aqueous washing solutions or pressurized
sprays. When soldering, it is recommended that no-clean flux
solder be used, as this will ensure that potentially corrosive
mobile ions will not remain on, around, or under the module
following the soldering process. For applications where the
end product must be cleaned in a liquid solvent, Picor
recommends using the QPI-6LZ-01, open-frame version of the
EMI filter.
