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

I have a similar question. What are the major differences between J-std-001 and IPC 610 class 3 ?

Can I manually tin them with solder specially the BGA's. Will that improve the solderability? What about corrosion of the copper? will it be prevented with the above process considering that after tinning of solder the solderability became acceptable

Um...I would reject those boards. skip plating is a process indicator...a bad indicator. IF your building to class 3...I would get the rep in ASAP and reject the lot.

I'm not a world class factory, but imo equipement wise, 3D paste inspection might be a thing for you to look into. grtz, Loco.

You're talking equipment classification. We're not sure what your component supplier means. What do they say?

Your IPC-610 workmanship manual will have the answer for you (I don't have the latest at my fingertips). Depends on what class you are building too, 1, 2 or 3 and the application of this connector on the product- which you must determine.

What do the heel fillets look like and what level of IPC-610 (class 1,2, or 3) are you working to? Do the joints on all 4 sides look bad or just the one side? Do other parts on the board look OK?
