Cross: IPC nor anyone else calls out recommended pressures for washers used to clean circuit boards. IPC and the other standards setting folk are in the business of defining the expected results or outputs of processes or acceptance criterion. They

Of course there are solvents which are less harmful to the environment than others. The operative phrase is �less harmful�. As a rule, water-based chemistries are �greener� than solvents. There are some solvent blends designed for aqueous-based eq

I know there must be a specification for this but I don't know what it is. What is the maximum psi setting for an air line that is used to dry assemblies off an aqueous cleaner? The assemblies are fixed but predominately SMT with many 0602/QFP/BGA co

The style of US standards has been moving away from such specifications for some time. So, the approach has become ... Here�s what I want ... Functioning, built to print, clean, undamaged boards. Here�s how I want you to do it ... I don�t care, jus

This is not a common method of defluxing. Vapor degreasers were the top choice pre-1989 but have given way to spray-in-air defluxing technology. Here come of the vapor degreaser manufacturers: Detrex http://www.detrex.com/ Baron Blakeslee http://

Well i guess you would not have to dry the boards but let me ask this, Are you hand cleaning water soluble flux in a sink? Never seen a cleaner without a dryer. Anyway temp and time for drying is easy to figure out. When boards are dry you have i

It depends on the flux type. If it's water soluble, it should be cleaned soon after reflow because OA flux remains active after reflow. If it's rosin or no-clean (low-residue), then the only concern is the longer wait time, the more difficult it will

Flashback time� Vapor degreasers, although still used in limited applications, no longer represent the conventional wisdom (due to multiple environmental issues). Aqueous-based technologies are the most common method of defluxing. Unlike most va
