I have seen it done exactly the way you do it and I think spraying will be better than dipping. However the best way is still to have your fluxer fixed and working.

If you move to the spray bottle, be sure to label it so there is no mistake as to the contents, you wouldn't want unlableled materials on the production floor, for a couple of reasons...

Good advices. What do you think of using a gravity paint spray gun? somebody recommend it to me, it will still depend on the operator but at least it would be more constant.. make sense? Saludos

1.Weight the paste 2.reflow the paste 3.clean the residue from the reflow ingot 4.weight the ingot By using simple calculation we can extract the percentage of metal or flux loading from the solder paste.

Walter: The things I'd look at first are: * Temperature of the water wash. I expect the solution to be in the 140-150*F range [Check with your flux supplier for recommended temperatures] * Temperature of the boards when entering the cleaning process.

So that is common when the temp on the wash is high? The temp was adjusted for a flux that required a higher temp. How much of an issue is this tin oxide?

Dear All, can please tell specifications of heat resistant glass plate which is used to flux application and process control of wave soldering. can you tell the suppliers of the same in India. BR, Gupta.

3-6 months, say, depending on the environment), I might consider a ramp-soak-spike profile to allow sufficient time for the flux to clean any potential contaminants. Cheers, ..rob

Armando, Is the problem in the same spot on the board with every run? If so, there might be something about that particular location that is part of the cause (ie. ground or power plane connection). It sounds like you're seeing blow holes, or insu

Dave is correct. You are running out of flux due to such a small solder deposit. Try shortening your overall time in the oven. Less than 4 minutes to peak is where I'd start.
