This is very true. Cascade has been used in very small quantities instead of a saponifier within the water wash (batch style) followed by a clean water rinse for more than one company that I know of, and it leaves little or no ionic residue. It cuts oils and other contaminants extremely well. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Jeffrey Bush Sent: Wednesday, July 05, 2006 1:46 PM To: [log in to unmask] Subject: Re: [TN] Rocha Laminate Voids.. Cascade also works very well for flux - leaves low ionics and never seemed to present an issue.

All, Recently we clean up residue on some boards with multipurpose Mr. Clean. Should I expect problems from it? Thanks. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Susan Mansilla Sent: Wednesday, January 04, 2006 5:16 PM To: [log in to unmask] Subject: Re: [TN] Rocha Laminate Voids.. If they are in the prepreg and are present as pressed, then there is a mismatch between the prepreg and pressing conditions. Are you able to do a flow test on some sheets of prepreg alone to see if the % flow is as expected? Can you determine if you are getting the predicted thickness of the prepreg layer? Are you able to determine if you are hitting the correct temp before you hit the higher pressure during the lamination cycle? Is the excess around the edges of the panel "frothy" in appearance? Just little thoughts that I would use to attack and "fix" the problem.
