Sounds like your flux to me. Since you cannot change the board or the machine, changing flux would be one question mark you could take away with a phone call and a sample. You will really be surprised how different fluxes can affect your final prod

5 Steps to Eliminate Bridges: 1. Establish (wave) Parallelism First and foremost, you must establish board-to-wave parallelism. This is the prerequisite to any wave solder process control. For an understanding of the power of this approach go to ht

Here is a nugget from the Data Sheet... Wave Soldering: Excess moisture on the PCB during soldering may lead to random solder balling and poor wetting of some solder joints. IT IS IMPORTANT that the flux solvent carrier (water) is fully evaporated a

..and he can put the flux in and keep it a secret too from his customer.. RSS profile on wave?? I never heard of a soak zone for wave preheat...you may be burning off your activator..hence, the beads. For wave preheat, your main goal is to ramp up

Likely causes of this are: -Preheat temp. too low -too much dross -uncured epoxy -PCB contamination ...also varify the solder flow over the wave is smooth.

I made my own wave measuring device using KIC2000 system. KIC2000 has automatic wave detection, so now I have a profiler for both reflow ovens and wave solder. The delmat carrier only cost $500. A guy, Samir, from this forum gave me the idea, actu

Is the flux rated for lead free? These higher temps will cause most lead rated fluxes to burn off prior to the wave. Jerry

This is funny. Poeple giving answers to a question that isn't specific. What if the shorts he is having are on the top of his board, caused by flooding or Omega wave too high?

Sounds like possibly too little preheat. Russ
