| I am trying to find information for one of our engineers on spray fluxing equipment. Years ago, I investigated these somewhat and now remember two suppliers -- Sonotek and AT&T. | | I was able to find information on Sonotek (http://www.sono-tek.c

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

Since you are mostly concerned about the flux and suspect an application issue, you need to do a few things to validate whats going on. 1. Forget about speed of processing, length of time to do the job. Focus on accuracy first, then speed. with that

Peterson: Ionic flux residues when combined with moisture and a voltage differential can plate conductive �fingers� on the surface of a PCB, but that doesn�t sound like what�s going on here. Your NC flux should not be particularly conductive. For
