Through-Hole Lead-Free Soldering
Information

The RoHS-compliant, Z version, through-hole products use
the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. The non-Z version products use lead-tin
(Pb/Sn) solder and RoHS-compliant components. Both
version modules are designed to be processed through
single or dual wave soldering machines. The pins have an
RoHS-compliant, pure tin 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.

Reflow Lead-Free Soldering Information

The RoHS-compliant through-hole products can be
processed with the following paste-through-hole Pb or Pb-
free reflow process.
Max. sustain temperature :
245

C (J-STD-020C Table 4-2: Packaging

Thickness>=2.5

mm

/ Volume > 2000

),

Peak temperature over 245

C is not suggested due to the

potential reliability risk of components under continuous
high-temperature.
Min. sustain duration above 217

C : 90 seconds

Min. sustain duration above 180

C : 150 seconds

Max. heat up rate: 3

C/sec

Max. cool down rate: 4

C/sec

In compliance with JEDEC J-STD-020C spec for 2 times
reflow requirement.

Pb-free Reflow Profile

BMP module 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. BMP will comply with JEDEC J-STD-020C
specification for 3 times reflow requirement. 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 23.

Sn/Ag/Cu solder.

MSL Rating

The EBVW017A0S14R0 modules have a MSL rating of 2a.

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-
025A). 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:
