THROUGH-HOLE SOLDERING INFORMATION
To ensure module performance and reliability,
adherence to IPC-A-610D standards for solder joint
acceptability is recommended.
The NDM1-12 module is designed for RoHS compliant
plated through hole mounting by wave or manual
soldering. The recommended pot temperature is a
maximum 270ºC with a maximum dwell time of 10
seconds. A maximum preheat temperature of 150ºC
with a preheat rate of 3ºC/s is suggested.

To prevent damage to the module during manual
soldering, special attention should be taken to avoid
direct contact between the hot soldering iron tip and
the pins for longer than 3 seconds.
