Through-Hole Lead-Free Soldering Infor-
mation
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-compli-
ant 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 addi-
tional information is needed, please consult with your Lineage
Power representative for more details.
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).
Solder Ball and Cleanliness Requirements
The open frame (no case or potting) power module will meet
the solder ball requirements per J-STD-001B. These require-
ments state that solder balls must neither be loose nor violate
the power module minimum electrical spacing.
The cleanliness designator of the open frame power module
is C00 (per J specification).
