full nitrogen tunnel

full nitrogen tunnel | 24 January, 2018


Could I ask for advice? We have new machines with a full nitrogen tunnel. Type of soldering nozzle: worthmann 5 rows and next nozzle (in this same machine) worthmann 7 rows. One person in my organization claims that the delta nozzle is not worth using in a full nitrogen tunnel but we have problems with the number of short circuits and processes and on old machines without a tunnel where there is only a local atmosphere and we have a delta nozzle the same products are soldering ok. What is your experience what about full tunnels? Are they actually not using the delta nozzle? Worthmann is turbulent and does not always work. I must seek advice.

Best regards
