Fuji IPII BGA

Electronics Forum | Thu Oct 28 23:04:34 EDT 1999 | Micah Newcomb

Has anyone out there tried placing BGA's with a Fuji IP2? Fuji says flat out no way but I think we can if we get them in T&R.

We have placed them before. You can only inspect the perimeter, but with the larger pitch in wasn't a problem. We also picked off matrix trays, but the BGA's we did had no center array. But if that type are on T&R it should work as well.

Can you please give me a pointer on where to find the component package orientation standard in the IPC? I think we'll work up a spec sheet for the folks in purchasing and let them handle the vendor side of this problem. Thanks for your help! JC

Chris: You can have more than "one question!!!" Anyhow, yes crappy solder paste can cause non-wetting, but before you go there understand why the paste is wetting some surfaces, but not others. Ta Dave F
