MOUNTING
Dip or wave soldering
The module should preferably be mounted on a
double-sided printed-circuit board, see Fig.3.
Input and output should be connected to 75 Ω tracks.
The connection to the common pins should be as close to
the seating plane as possible.
The maximum permissible temperature for the solder is
260 °C. It must not be in contact with the joint for more than
5 s.
The total contact time of successive solder waves must not
exceed 5 s.
The device may be mounted against the printed-circuit
board, but the temperature of the device must not exceed
125 °C.
SOLDERING
Hand soldering
If the printed-circuit board has been pre-heated, forced
cooling may be necessary immediately after soldering to
keep the temperature below the allowable limit.
The maximum contact time for a soldering iron
temperature of 260 °C up to the seating plane is 5 s.
