Has anyone in the industry had even a fair amount of success inspecting reflowed solder joints to IPC class 3 standards? I am not interested in hearing from system reps or people who work for an AOI manufacturer. Thanks,

90% of the assemblies our company produces are class 3 and we have no problem at all inspecting or getting class 3 quality through reflow. Rarely do we have touch up because of insufficient or poorly reflowed solder joints. What are the problems you

We are not having a problem, we have a customer that would like us to use post reflow AOI to inspect the solder joints to class three. I would like to see if anyone is having sucess doing this.

I'm running intrusive reflow. What happened was when the board went thru' the first reflow ( which is secondary side ), at Post reflow, I can see the solder joint quality is very good smooth and shiny. But when we proceed with the 2nd reflow, at Post

We had the data at the time and it was quite high. More false calls then anything. I do not have the data anymore it since has been archived. When the system was introduced we had 1 engineer and 2 operators trained for programming and running the

I need teoretical info for theme "Matted surface vs solder ball". Is it right that some solder pastes decrease solder balling but give matted surface after reflow? That diference between these pastes and others? Are the matted surface worse solder b

About 2 years ago our company tried to go with a post reflow AOI inspection. This AOI was suppose to be able to inspect to a level class 3 product. **It is impossible** You cannot inspect for a heel fillet and inspecting for poor wetting is a very

It's easy to reject everything is it? IPC offers excellent training courses for inspectors in interpreting A-610.

Yes we are using "silicones", but to find this contaminant we were looking for "silicon" the element by SEM/EDS. We use Dow materials and my contact there is checking to see if they have any info.

Paul, do you have any kind of false failure data for the application you struggled with? Also what amount of manpower did you use to operate the system(s).
