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

Dave Try Transair Legris, They have a pretty slick system which will compare in cost to your black pipe but offers many advantages and it is clean.

Copper is best! I've seen troubles with black pipe - the pipe is not always clean on the inside and debris or mill scale makes it into your equip. eventually. We've also used PVC to get by/quick fix and we always ended up blowing a fitting or even

We encounter this kind of issue. We use stencil clean in the stencil printer and also use air to blow aperture after cleaning. We are having some luck !!

The smallest particle sixe for type 3 paste in 25 microns. This is far to big to remain airborne.Therefore I would suggest to continue to use air to clean stencils as it does clean the apertures effectively.What solvent is used to clean the stencils?

1.- Clean bottom and top stencil with a cloth/alcohol at same time.Pay special attention to fine pitch locations. 2.- Clean again bottom stencil side .To prevent any residual of solder 3.- Blow air with a air gun under the stencil to remove the solde

I need a second opinion. My operators us an air hose to clean out the aperatures in our stencils. It is my contention that this puts solder into the air, and could be harmful to us. It is the operators contention that I am crazy, and cite as proof

I agree with the others - I just don't see the danger. We've been using air to help clean stencils for decades.

Sorry fellas -disagree. We only clean our stencils in the ultrasonic machine at the end of the run. If the same pcb is up the next day we clean them by hand. We use Electrolube SSS and the used rolls from the in line under stencil cleaner. Wipe the
