NOTES
(1)
Specifications typical at Ta=+25C, resistive load, nominal input
voltage, rated output current unless otherwise noted.
(2)
Specifications subject to change without notice.
(3)
Water Washability - Calex DC/DC converters are designed to
withstand most solder/wash processes. Careful attention should
be used when assessing the applicability in your specific
manufacturing process. Converters are not hermetically sealed.

Figure 1.
The profile in Figure 1 should be used as a starting point for your own
experiments. Obviously your optimal profile will be a function of many
factors including, type of paste, paste thickness, board thickness,
number of conductive layers, copper weight, the density of surrounding
components, etc. It is recommended that the peak temperature
should not exceed +235C for an extended period of time.
