Hello 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 wor

Thanks Jim, that should help. And yes, there is light at the end of the tunnel.... now : ) -Sasu-

Hi, Is it necessary to have a tunnel nitrogen? Is it a very common practise amongst contract manufacturers ?

Hello davide, the biggest advantage you'll find with a complete N2 tunnel is the minimization of oxidation during board preheating. Using only an inerted solder pot allows the oxidation to build up throughout the preheat stages and introduces contami

Hello Kris, No, it's not necessary to have a nitrogen tunnel setup. A nitrogen tunnel allows a process to go the extra step in providing higher quality through less defects. I can't really speculate on it's use in contract manufacturers mainly becaus

We are looking for a way to cure conductive adhesive. I heard about curing times from 2 hours and more. But I also received information that curing can be done in 10 minutes at 120 C. Of course it also depends from the type of glue. But the question

We intend to use VOC free fluxe in our nytro machine. Does anybody know if there can be problems with water ie. solvent residues in the tunnel. Perhaps there are some white papers available on that issue.

| Can anyone tell me any posible ways to help cut down on solder dross in an inert environment wave???? Any suggestions would be helpful. It depends on how the environment is inerted. Is it a hood, tunnel, or boundary (Electrovert Contour) system?

I want to know the advantage of using complete inert soldering wave machine (with Nitrogen, Tunnel concept) in comparison to use just a soldering machine withe inerted solder pot. Thanks

Metallization failure. A defect such as voids, cracks, separations, depressions, notches or tunnels or any combination in the cross sectional reduction that is a basis for rejection.
