There is a ISO Standard 14644-1 Class Limits, but I don't know if if this is applicable in the "so callled" SMT standard production scenaraio and if so, what class would it be? I hope that some other nice guys will correct me, or have i totally lost

Good Morning, I had looked into this several years ago. The Swiffer dust mops use static to capture and contain dust particles. That would make this a huge ESD concern. Electrical SMT equipment is grounded so any charge potential generated would be

It's rough on tooling and not much you can do about it. Your best bet is to get it into a CNC mill with coolant if you can. Keeps the dust down too as dust particles from durostone are very irritating in the air in case you didn't notice already.

Thanks for your answer, contamination in form of fine dust particles. I don't know why but i need to clean this rings one per shift. I will post some pictures tonight. This contamination is affecting the solder wave on the nozles, when i clean the ri

I had a similar problem a few years ago when glue printing. Our production environment wasn't to clean room standards and there was a bit of air born contamination floating around which would gather on the PCB surface (also our rough board edges wou

I have had OSHA strap accumulative "sniffers" onto wave operators and maint. tech's. THe sniffers collect air bound particulates and trap them into a filter. Later the filter is analyzed and an operator exposure rate is determined. They also will la

Obviously a totally clean floor is the best. So what if you have 1 particle of dust on your entire production floor? Is that 1 part per million (1 PPM)? or is that 1 part per billion? or 1 part per ???? How do you measure dust and come up with a

There are different options for de-paneling routers. There are two basic types, in-line and stand-alone. Do you need in-line for high volume? The stand-alone systems have manual insertion trays, one or two trays. Also, after de-paneling or laser ma

Hi, Use nitrile or latex gloves for handling your product from your pre-coating cleaning step onward. In my opinion, conformal coating should be isolated from the rest of the factory floor. I'm not saying you need a clean room or even a white room.
