Awwww, man. I was looking for something a little less on the anecdotal side for our local municipality's environmental stewards.

Just wondering if anyone knows this off the top of there head. I might be able to figure out the math based on surface tension (this is 63/37 so the data is out there) but I REALLY do not want to put that kind of effort into this. :/ Editing to clar

Yep. What I'm really looking for is the minimum radius of curvature for 63/37, which is a function of it's surface tension. It's physical properties issue, not an agency issue. I've seen some references that I have interpreted to mean that it's some

Has any anyone established / published quality standards for BGA solder joints? Is IPC-A-610 in process of adding standards for BGAs?

Sorry that I'm so late responding. Your new additon probably has 'backee stains on the floor already. Assuming we're talking about a fairly standard board assembly area, you don't need to specify air quality. 1 We specify * Particulate: Level to b

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

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