Lead Free Soldering
The –Z version SMT modules of the HW/HC series
are lead-free (Pb-free) and RoHS compliant and are
compatible in a Pb-free soldering process. Failure to
observe the instructions below may result in the
failure of or cause damage to the modules and can
adversely affect long-term reliability.
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for
Nonhermetic Solid State Surface Mount Devices) for
both Pb-free solder profiles and MSL classification
procedures. This standard provides a recommended
forced-air-convection reflow profile based on the
volume and thickness of the package (table 4-2). The
suggested Pb-free solder paste is Sn/Ag/Cu (SAC).
The recommended linear reflow profile using
Sn/Ag/Cu solder is shown in Figure. 74.
MSL Rating
The HW/HC series SMT modules have a MSL rating
of 1.
Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensitive surface mount
packages is detailed in J-STD-033 Rev. A (Handling,
Packing, Shipping and Use of Moisture/Reflow
Sensitive Surface Mount Devices). Moisture barrier
bags (MBB) with desiccant are required for MSL
ratings of 2 or greater. These sealed packages
should not be broken until time of use. Once the
original package is broken, the floor life of the product
at conditions of ≤ 30°C and 60% relative humidity
varies according to the MSL rating (see J-STD-033A).

HW/HC004/005/006 Series DC-DC Power Module:
The shelf life for dry packed SMT packages will be a
minimum of 12 months from the bag seal date, when
stored at the following conditions: < 40° C, < 90%
relative humidity.
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 requirements 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).
