| I have a severe problem with flux residue being drawn up the vent ducts of my reflow oven. This residue reaches a critical mass then begins to flow down the ducts and becomes very messy. I run a no-clean process and use IR oven. Has anyone else o

I get white residue on my PCBs after vapor degreasing. No comments on the vapor degreaser. Yes, I still use one of these. I use a vapor degreaser and a 1,1,1 replacement solvent due to the quick clean and quick dry times. Anyway, I only get white

| We've got a continous flow cooling problem from our wave solder process into ICT. Our current configuration is a flatbelt conveyor into a manual de-pallet process, operator then places on to an edge conveyor. We've tried muffin fans, look good bu

Upinder, Using IPA does not cause the residue, it simply exposes it. Given that all fluxes leave reisdues, it follows that these MUST be benign - but how do you know, and how do you control it. You are using flux to remove oxides and give you a go

Dave, The first step would be to learn to accept the residue. IPC class 2 has no problem with it. If that is not possible, I am not sure why a no clean is necessary- but I will take your work for it. Alcohols will dry out the residue, and turn it

Steve: I thought Kyzen products were "additives" to either aqueous or semiaqueous inline or batch machine cleaning processes. I'm trying to clean the no-clean residue from a few components that can not bear to see water. Can you use Kyzen products
