Data Sheet  
JHC/JHW350 Power Module; dc-dc Converter  
March 26, 2008  
18 – 36Vdc or 36 – 75Vdc Input; 28Vdc Output; 350W  
Layout Considerations  
The JHC/JHW power module series are encapsulated  
aluminum case packaged style, 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. Also avoid placing via  
interconnects underneath the power module.  
For additional layout guide-lines, refer to  
FLTR100V20 data sheet.  
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 Lineage Power Board  
Mounted Power Modules: Soldering and Cleaning  
Application Note (AP01-056EPS).  
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. Not all RoHS-compliant through-hole  
products can be processed with paste-through-hole  
Pb or Pb-free reflow process. If additional information  
is needed, please consult with your Lineage Power  
representative for more details.
