Option M

Surface mount version.

Note: Precautions should be taken when reflow soldering

the SMD version, option M. The reflow soldering instruc-

tions below should be strictly adhered to. An inadequate

soldering process may permanently damage the converter

or degrade its performance and Melcher will not honour any

guarantee/warranty claims resulting from damage caused

by ignoring the soldering instructions.

Infrared soldering is not permitted.

The surface mountable version of this product is assem-

bled with high melting point solder (227 C) to ensure that

the solder joints of of the internal components do not de-

grade in the end users SMD soldering process.

This product is only specified for "Forced Convection

Reflow Soldering" (Hot Air). Any conventional soldering

profile is acceptable provided that the restriction curve be-

low is not exceeded at any time during the reflow process.
