first I am personally not a fan of dross reducers. We have enough issues with contaminants on boards (high impedance analog) so i do not want to introduce more contaminants into the process. Second I have not had much luck with any dross reducers. We

Make sure you are providing an adequate moisture bake out prior to wave soldering. It sounds moisture related since is so random. I would suggest perhaps 120C for a minimum of 8 hours to drive the moisture out, and then complete your wave soldering

I wonder if the wave was the proper place to work for someone with thought processes like that!!! Although burning plastic is sometimes and nice change from flux fumes!!! Then again, our hiring rep states that she will never work at a place that em

Also, what about the gap spacing on your machine between the top of the second wave baffle to the bottom of the finger? Ours is at 5.7mm. Thx.

We use Datum Dynamics for selective wave pallets and have been very happy with their work and fast turn around. We also get all our press fit fixtures from them. Check out their web site www.datumdynamics.com

Question: Do you run your pallets hot or cold thru the wave? I ask this because if you run your pallets cold the board will never preheat to the correct temp. thus, your flux won't activate properly. James

I had confused by same problem, the reason I found is the interval between wave soldering and cleaning is too long and did not set the temp. of D.I water at 120F~150F. Kester flux is good. Rgs, Wister

Sounds like you are running your conveyor too fast. Check your profile and see if your board is getting hot enough "max 125c on topside prior to hitting the wave. If so then slow it down, if not then increase your preheats and slow it down.

Are they visibly "popped" after wave but not before? Remember that many BGAs, especially plastic (PBGA) are very moisture sensitive and even 24 hours or less out of a controlled environment violates exposure rules.

What approach do you you use to reducing wave solder dross? What is your experience with Klennox? Dave F
