Surface Mount Assembly
Soldering:
The following instructions must be observed when
soldering
instructions may result in failure or significant
degradation of the modules performance. Power-One
will not honor any warranty claims arising from failure
to observe these instructions.
This product is approved for forced convection reflow
soldering only.
The curves below define the maximum peak reflow
temperature permissible measured on Pins 1 and 10
of the converter.
The

diallyl ortho-phthalate moulding compound commonly
used for packaging of electronics components.
passes NASA outgassing tests and is certified to MIL-
M-14. It’s coefficient of thermal expansion is
equivalent to FR4.
The gull wing leads are formed to ensure optimal
solder joint strength and structure. Furthermore they
facilitate visual inspection (manual or automatic). The
leads are formed from a 97% Cu alloy plated with Cu
and Sn 90. This material is commonly used in the
manufacture of integrated circuits. It has good
corrosion resistance and exhibits the nobility inherent
to all high copper alloys. Unlike brasses, this material
is essentially immune to stress corrosion cracking. It
also exhibits excellent solderability. It is readily
wetted by solders and performs well in standard
solderability tests. (Dip of Class II or better).
The product is manufactured with a patented
process, which is fully automated, and ‘in-line’. This
ensures that there is no contamination or mechanical
stress on the lead-frame so that the co planarity and
solderability are maintained.
The product is shipped in JEDEC style trays to
ensure preservation of the co-planarity and enable
fully automated assembly in the final application (co-
planarity within 0.1mm).

Pick & Place Assembly:
The product is designed to have a large flat area in
the center of the top surface to serve as a pick up
point
equipment. The ‘open board’ construction of the unit
ensures that weight is kept to a minimum. However
due to the relatively large size of the component, a
large nozzle (> 8mm, depending on vacuum pressure)
is recommended for picking and placing.
The unit may also be automatically handled using
‘odd-form’ placement equipment, with mechanical
grippers. For this type of equipment the end edges of
the device, which have no leads and also feature the
greatest dimensional accuracy, should be used as
pick-up points.
