Layout Considerations
The JNCW016A0R power module series are constructed
using a single PWB with integral base plate; as such,
component clearance between the bottom of the power
module and the mounting (Host) board is limited. Avoid
placing copper areas on the outer layer directly underneath
the power module.
Post Solder Cleaning and Drying Considerations
Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The result
of inadequate cleaning and drying can affect both the
reliability of a power module and the testability of the
finished circuit-board assembly. For guidance on
appropriate soldering, cleaning and drying procedures, refer
to GE Board Mounted Power Modules: Soldering and
Cleaning Application Note.
Through-Hole Lead-Free Soldering
Information
The RoHS-compliant through-hole products use the SAC
(Sn/Ag/Cu) Pb-free solder and RoHS-compliant components.
They are designed to be processed through single or dual
wave soldering machines. The pins have an RoHS-
compliant finish that is compatible with both Pb and Pb-free
wave soldering processes. A maximum preheat rate of 3C/s
is suggested. The wave preheat process should be such
that the temperature of the power module board is kept
below 210C. For Pb solder, the recommended pot
temperature is 260C, while the Pb-free solder pot is 270C
max. The JNCW016A0R cannot be processed with paste-
through-hole Pb or Pb-free reflow process. If additional
information is needed, please consult with your GE
representative for more details.
