Thanks a lot guys, is there a way to measure air quality? Like ppm of airborne particulates? Thanks again

Will there be any issue if soder paste of SnPbAg is used for airborne application (PCB)

Use a cartridge that's approved [conform to OSHA 42 CFR 84] to provide respiratory protection against organic vapors, chlorine, hydrogen chloride, sulfur dioxide, chlorine dioxide, and hydrogen fluoride with a P100 particulate filter which is effecti

It would depend on the solder paste but the stuff we use is heavy enough that it wont go airborne. and theres really no other way to clean the apertures on a 0402 or similar part.

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?

What about trying to clean these stencils with a proper stencil cleaner? This way you wouldn't have to worry about sending anything airborne.

What do you mean by "airborne"? We have been using SnPbAg for 15+ years to build assemblies to IPC class II standards although with most assemblies going to Pb free, we are not using it near as much as we used to.

The hazards of a wave solder machine are: * High temperature * Airborne metal oxides * Flux fumes

and one more thought about your original question, if the flux does look really strange and out of place, then inspect the reflow oven. A great amount of flux condensation in the reflow oven's cooling zone can cause crystalized flux to become airbor

I do not have a answer for you, but it sounds like electro-static charge is making air-borne particles stick to the machine. What are the air handling conditions? Could be you need a better filtration system. I use a HEPA filter system. I've always w
