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

Hello all, We use pressurized air from a blower to blow off excess water from our pcb assemblies after wash. I'm concerned that this could potentially cause esd damage to sensitive assemblies. Is anyone aware of a device that can correctly ionize the

Hi, My company is using HEPA filter to improve air quality coming out of oven/wave solder. But the cost of such filter is quite high and we need to improve the consumption. Any suggestion from fellow experts out there? a. Anybody did a cost reduc

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

Grease filters work well. They're cheap, easy to clean and come in all sizes. Will not reduce your air flow by much either.

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?

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

I would also be concerned about spreading solder paste on the walls/floor/equipment downstream of the air. This would then get transfered to hands, clothing and shoes. In turn, tracked out to the rest of the floor/building or even to the home of em

This is not an HVAC unit. This is a small unit attached to a production machine to keep the solder paste from drying out prematurely or slumping. The volume of air being cooled and desicated would be less than 3 or 4 cubic meters.

Are you still facing this issue? Well, I am so late to get to know this. I think you first check your evaporator coil if your air conditioner is still freezing up. It has been seen that a dirty airflow coil stops the proper flow of air through it. It
